Win 10 Group policies:
Microsoft introduced with Windows 10 build 1803 „Camera Privacy Settings”. There is the possibility todisable/enable the usage of UVC cameras. Please ensure when using DVM6, ICC50 W, S9i, or EZ4
W/E that “Let apps use my camera” is enabled.

USB3 cameras:
Leica USB3 cameras are tested with USB3 PCIe cards from DeLock. These cards have a
Renesas PD720202 chipset. Leica strongly recommends to use these cards. The majority of
the Leica USB3 cameras are delivered with this USB3 PCIe card.
If you plan to use a different card or an onboard-USB port with a different chipset, please makesure you have the latest drivers from the card manufacturer and the latest Windows updates
installed. Leica does not assume any liability when not using the recommended USB3 PCIe
card.
Please also branch the internal power supply when using a card.
Due to the high power demands of some cameras, and the large amounts of data they deliver,
Leica recommends to use each camera on a separate card. Leica recommends not to use
other instruments with high power requirements, such as external hard drives, on the same
USB socket.
Some computers have a USB3 charging port (USB3 with a flash sign). We do not recommend
to use this port, since the camera will never power off and can prevent the computer fromrebooting.

Warnings
Warning!! LAS X 3.7.3 is a Widefield Research release only. Do notinstall on Confocal systems nor Applied Microscopy systems.

Warning!! LAS X 3.7.3 is not released for EM Cryo CLEM

Warning!! LAS X 3.7.3 is not released for Windows 7

Operating System
LAS X 3.7.3 is a genuine 64 bit program and runs on Windows 10.

2.1
LMD

Compatibility to LAS, LAS AF, former LAS X versions and2.1.1 Compatibility to former LAS X versions
Former LAS X versions on widefield research systems can be upgraded with LAS X
3.7.3.
Former LAS X versions on EM Cryo CLEM systems can be upgraded with LAS X 3.7.3,
but the performance of the PC might be not good enough to have a smooth software
process.

2.1.2 Compatibility to LAS
LAS X 3.7.3 can read and process single images generated with LAS versions.
However, image series generated with LAS need to be imported with the LAS X fileimporter by entering the metadata manually.
LAS versions cannot read data acquired with LAS AF or LAS X software versions.

2.1.3 Compatibility to LAS AF versions
All LAS AF 4 versions can be upgraded with LAS X 3.7.3

LAS X 3.7.3 and LAS AF 2.x cannot be installed on the same computer, unless it isconfigured with a dual boot option. Before installation of LAS X 3.7.3 on an offline
workstation running LAS AF 2.x, it is necessary to uninstall LAS AF 2.x.
LAS X 3.7.3 does not accept the LAS AF 2.x license dongle and vice versa. Please
make sure that the correct dongle is inserted in the workstation. LAS X dongles havea Leica logo engraved and a shiny surface to distinguish them from LAS AF 2.x
dongles.
LAS X 3.7.3 can read and process files generated with LAS AF 2.x versions and LAS
AF 4.x versions. LAS AF 2.x versions however cannot read all data acquired with LAS
AF 4 or LAS X software versions.

2.1.4 Compatibility to Leica LMD Laser Microdissection
LAS X is fully compatible to Leica LMD application software and can be installed on
the same workstation.
Important note: Use only one software at a time. The LMD application software and
LAS X software cannot be used simultaneously.
LMD application software V8.1 and higher support Win10.

3. Product Security Fix
Update of license component to a new secure version
Please see the official communication for detailed information
https://www.leica-microsystems.com/company/product-security/product-security-updates/

4. Important Information
Fluo-DIC and Fluo-Ph Combi Mode on DM6 and DM4: Combi Illumination within the
Illumination Settings panel needs to be switched to TL before activating a live image.
Otherwise the TL illumination will be missing in the Combi Mode. The missing TL
illumination only affects the live image but not image acquisition.

Quantum stage (LMT200): after restart of the stage, speed and acceleration settings arereset to default even though LAS X displays the speed and acceleration settings prior torestart.
Workaround: Configuration->Microscope->XY stage ->define speed and acceleration
again. Alternatively keep the stage switched ON.

Shading correction: when switching between channels during live image, the shadingreference is not changed accordingly.
Workaround: switch live image off and on again.

When acquiring multiple channels via Capture Image, only one shading reference isapplied to the captured images. During a timelapse experiment the shading correction isapplied properly.



EDOF processing does not work for .lof files.
Workaround: use .xlef or .lif files for EDOF processing.



M205 FCA multichannel timelapse experiment with shutter control modes optimized andafter each image: all images are acquired properly but light shortly switches on and off
again after each cycle.



M205 FCA multichannel experiment with Lambda then Z acquisition: all images are
acquired properly but light switches on too early.
Workaround: use Z then Lambda for acquisition.

Navigator: although the live button shows that live image is OFF, the live image and lightstay ON after creating a focus map with the “Find all by Autofocus” function.

LAS X 3.7.3 Release Notes for Widefield Systems

14

Workaround: switch live image ON and OFF again.
Auto exposure doesn't regulate the exposure of images with low brightness values.



If SVI Huygens software is opened from LAS X by function “send to Huygens essential”
the GPU processing capabilities of the Huygens license can’t be used. However, if
Huygens is launched independently the GPU is used for processing.

High-speed triggered sCMOS cameras or high-speed Navigator experiments require thetemp file being located on a SSD RAID NVMe hard disk. Temp file on a normal SSD disk
may cause the experiment to stop without being completed.

"Data handling in folders" requires more space on the temp drive compared to working in
projects. For large experiments it is recommended to use "Data handling in projects".

Experiments with high-speed autofocus and camera in global reset require theexperiment to start with a selected acquisition channel. Starting the experiment with aselected autofocus channel can lead to underexposed images.



THUNDER Imager EM Cryo CLEM: DFC9000 GT is the tested and approved camera for
the THUNDER Imager EM Cryo CLEM. No other camera should be used.

When installing LAS X from USB-Stick, Trend Micro blocks the AUTORUN.inf.
Workaround: start setup.exe manually.

When using USB cameras: please disable "USB selective suspend setting" in Windows
advanced power settings. LAS X workstations have these settings already preset.



HDR acquisition with camera: only 8 bit, high-speed acquisition not supported

LAS X 3.7.3 Release Notes for Widefield Systems



If you use a multicolor lightsource on your system, you've to set the IL shutter mode in
the hardware configurator to “Always open after changing contrasting method”.
Otherwise the hardware shutter of the fluo axis stays closed.



LAS X Navigator is not available within the Easy Operation mode.



Use Do not use Navigator in combination with data handling "Work in Folders". Navigator
experiments require data handling "Work in Projects” (Configuration tab -> User
Configuration -> Data handling -> "Work in Projects")

Stopping a running mark and find experiment may cause loss in data.
Workaround: wait till mark and find experiment is finished.

Do not stop an experiment with remaining manipulation steps in the Scan Sequencer. If
stopped, the remaining manipulation steps cannot be deleted from the Infinity Scanners
memory. All subsequent manipulations will trigger the remaining manipulations andnot the actual definition.



The scan sequencer works with AFC in continuous mode but not with the image based
autofocus (HSAF).



Z-stack acquisition with finefocus in combination with "AFC on demand" is not supported.



Do not change hold position during AFC on demand while AFC is activated.

When performing THUNDER Mark and Find experiments on the fly, the timestamps are
written into the raw data but not into the thunder processed files.

Best focus will not work if limits of capture range are too close to the image focus.
Workaround: increase capture range.

In high speed multi-channel T-series with shutter always open light intensity might differ
between live image and acquired image.
Workaround: use shutter mode “after each image”.

When zooming into an image with measurement lines the measurement lines are notzooming accordingly.
Workaround: perform measurements after zooming.



If LAS X is to be installed on the same workstation as the LMD application software,
install first the LMD application software and then the LAS X Software afterwards.
Important note: Use only one software at a time. The LMD application software and LAS
X software cannot be used simultaneously.



If an objective is changed via LAS X Inplace Configuration it can happen that in the AFC
Panel the AFC cannot be set to “HOLD FOCUS POSITION” or “USE AFC”. The
checkbox might be grayed out.

Workaround: Close LAS X and use the HW configurator to teach in the objectives again
followed by power cycle the microscope. Then start the LAS X again.
After acquiring an image with FLUO-PH or FLUO-DIC the illumination panel disappears.
Workaround: switch to a different contrasting method (not FLUO-PH or FLUO-DIC).

The Leica Lamphouse for TL illumination works only in highspeed with I2C connection.
BNC Connection is not supported for highspeed.



XLED light source in combination with sequencer advanced and t-series with image
streaming and high-speed autofocus: if acquisition channel and HS-AF channel both use
the 365nm or 460 nm line, the HS-AF images are illuminated properly, but there is nolight on the sample for the acquisition channels.

When using DFC9000 GT with exposure time < 1,5ms and light source X-LED with
460nm, some images in an external triggered time series may not be illuminatedcorrectly.

Image export: Do not delete experiment data during export of the experiment. Otherwise
the exported data will be corrupted.

Image export: Do not close LASX from Process tab during image export - this may leadto data loss.



3D Surface Viewer is not supportedHardware Configurator: TIRF cube alignment: After power up of the microscope - the firststart of the TIRF cube alignment can accidently terminate the Hardware Configurator
application. In this case a restart Hardware Configurator application and a rerun of the
TIRF cube alignment procedure is recommended.

Hardware Configurator: If you teach in a new TIRF cube or replace an existing one withanother type in the Hardware Configurator, please do not forget to fine-tune afterwards.
Otherwise, the software may use incorrect TIRF fine-tune information.

Restriction for DMI series with manual transmitted light arm: the light intensity of atransmitted light channel can drop to ZERO when changing between channels in the lightpath settings interface. This restriction does not apply to DMi8.
Workaround: keep live image always on when changing between channels

Stereomicroscopes: Measurement function in live mode works incorrectly after an
objective change. Please leave and re-enter the live mode to readjust the measurement
function.



Mobile Connection: iPads require iOS10 to connect with LAS X.

LAS X is released for use with Windows Defender Antivirus and TendMicro Antivirus.
