AvaSpec-ULS2048XL-EVO SensLine High UV and NIR
Sensitivity Back-thinned CCD Spectrometer
AvaSpec-ULS2048XL-EVO

Combining exceptional quantum efficiency
with high-speed is the value proposition of
the AvaSpec-ULS2048XL-EVO spectrometer.
Unlike many back-thinned CCD spectrometers, which have two dimensional arrays,
the ULS2048XL-EVO has large monolithic
pixels of 14x500 microns with exceptional
efficiency in the UV, from 200-400 nm, andthe NIR, from 950-1160 nm. The instrument
also has an electronic shutter, which enables
integration times as low as 2 microseconds.
To further enhance sensitivity, a detector
collection lens is available which improves
sensitivity up to 60% when combined withlarger core fibers.

The AvaSpec-ULS2048XL-EVO uses theAS7010 electronics board offering USB3 (10times faster than USB2), Gigabit Ethernet andbetter signal processing.
Connection to your PC is handled via a USB3connection or Ethernet, delivering a scan
every 2 milliseconds. The instrument comescomplete with AvaSoft-basic software, USB
cable and an extensive manual.

Options include order-sorting filter, to reduce
2nd order effects and purge ports for deepUV measurements. The AvaSpec-ULS2048XLEVO comes with a wide range of slit sizes,
gratings and may be configured with SMA or
FC/PC fiber-optic entrance connectors.

AvaSpec-ULS2048x64-EVO SensLine
High UV and NIR Sensitivity Spectrometer
Alongside the cooled AvaSpecULS2048x64TEC-EVO with low-noise
detector, Avantes also offers the more costeffective, uncooled AvaSpec-ULS2048x64EVO. With its standard 2048x64 backthinned
detector, thisspectrometer is perfect for less demanding
applications in the UV and NIR range.
For applications that require integration
times lower than 2 seconds, the cooling
option is often not needed. For example,
this uncooled AvaSpec-ULS2048x64-EVO has
an established track record in various DOAS
applications all over the world because of
its high UV response and 0.9 mm detector
height that enables detecting the
wavelengths of interest.

Options include an order-sorting filter, toreduce second-order effects and purge ports
for deep-UV measurements. The AvaSpecULS2048x64-EVO comes with a wide rangeof slit sizes, gratings and can be configured
with SMA or FC/PC fiber-optic entrance connectors.

AvaSpec-ULS2048x64-EVO

The AvaSpec-ULS2048x64-EVO uses theAS7010 electronics board offering USB3 (10times faster than USB2), Gigabit Ethernet andbetter signal processing.

AvaSpec-ULS2048x64TEC-EVO SensLine
Thermoelectrically Cooled Fiber-Optic Spectrometer
AvaSpec-ULS2048x64TEC-EVO

The AvaSpec-ULS2048x64TEC-EVO
is an updated version of our AvaSpecULS2048x64TEC spectrometer, withimproved electronics and cooling.

The AvaSpec-ULS2048x64TEC-EVO uses a
special low-noise version of the 2048x64
detector with integrated cooling.

This instrument enhances the Sensline series
with its cooled, back-thinned
detector. The back-thinned detecor has goodsensitivity in the UV and IR region.
The 64 pixelheight (0.89 mm) enables catching as many photons as possible while thecooling enables long integration times up to
120 seconds with low-noise levels.
The instrument features Peltier coolingdevice integrated into our exclusive ultra-low
stray light optical bench, which can reduce
the temperature of the CCD chip to -30°C
against ambient, improving the dark baseline and PRNU level significantly. The detector cooling also reduces the dark noise by afactor of 2-3.

All the features mentioned above make this
instrument ideally suited formeasuring low-light applications, such as
fluorescence or low-light Raman measurements.
Optimal flexibility is guaranteed with thereplaceable slit, making the instrument
suitable for various kinds of applications.
The above mentioned qualities make the
AvaSpec-ULS2048x64TEC-EVO an excellent
choice for low light-level applications, suchas fluorescence and Raman measurements,
where integration times of more than 5 seconds may be needed.
