Pixel correction, DSNU/PRNU calibration, more accurate quantitative analysis
To improve the overall performance of the camera, the Dhyana 400BSI (V2.0) was calibrated in DSNU (dark signal nonuniformity) and PRNU (photo response non-uniformity) characteristically. After calibration, the DSNU value reduced from 0.3e- to 0.2e-, the PRNU value reduced from 1.6% to 0.3%. Thus the new upgraded camera has a more sophisticated capabilities, making it more suitable for quantitative analysis applications.
-15°C lower temperature to reduce the impact of noise
The dark current is closely related to the operating temperature. When the camera is at a low and stable temperature, the generation of dark current will greatly reduce, thereby it reduces the influence of noise on the imaging and brings benefits to SNR for long exposure low-light applications.
Wide spectral response range, high sensitivity
With its ultra-low noise, the advantage of the quantum efficiency in Dhyana 400BSI (V2.0) is very significant. This is a huge breakthrough for scien-tific applications, not only in the visible region, but also in the ultraviolet and near-infrared.
74fps using CameraLink, 40fps using USB3.0, faster data capture
In addition to the signal to noise ratio advantage, the Dhyana 400BSI (V2.0) has enhanced transmission speed, on one hand though the new CameraLink interface to meet the needs of high-end imaging research for higher frame rates, on the other hand through hardware improvements that increase the USB 3.0 throughput. These have achieved the ultimate transfer rate of 74fps with CameraLink and 40fps with USB3.0 at 4.2 MP full resolution.
