Dhyana95 V2ROI

Dhyana95 V2 adds a STD high speed readout mode,of which the frame rate is up to 48fps@4.2MP whichis twice as the normal mode. It can be achieved
grogressively by using ROI function for applications
demanding special frame rate.

Superior background with accurate calibration
Dhyana95 V2 now can provide a superior backgroundfor quantitative analysis applications. The DSNU/PRNU
have reached the international optimum of 0.2e- andDSNU

0.3% respectively, as the problems from sensor
production process, such as edge glow, dead pixels aswell as pixel non-uniformity, all have been calibrated
accurately.

Key Features

95% quantum efficiency, and excellent SNR
The Dhyana95 V2 uses backside-illuminated sCMOS thinned chip technology to avoid light interference from the wiringlayer. It has excellent response capabilities in the ultraviolet, visible and near-infrared bands, with a peak quantum efficiencyof up to 95%@560nm, and when the number of incident photons are more than 3 , it can have a better SNR
performance than the typical EMCCD camera of 97% peak QE .

Thanks to the 11um large pixel , Dhyana95V2's full-wellcapacity can be up to 100,000 electrons. Advanced HighDynamic (HDR) mode, through dual-channel gain conbined,
it can present high-quality images with rich details of dark

2" area, large field of view
The 2" array can not only adapt to more opticalinterfaces and deliver a greater field of view, but also
results in fewer lens switches to find the area ofinterest on the sample.

Soft X-ray Detection
The distinctive features of Dhyana95 make it an excellent alternative to back-illuminated CCDs which are commonly
applied in soft X-ray applications of previous-generation synchrotrons, such as coherent scatter experiments. They would
greatly benefit fully from the Dhyana95's high frame rates.
