Photometrics Evolve™ 128 EMCCD Camera
128 x 128 imaging array
24 x 24-μm pixels
Evolve™ 128擁有優異的性能，能供提供業界最低的 read noise，dark current，再加上electron multiplication (EM) gain，在低亮度的情況下，像是小動物活體成像到單分子螢光，都可以提供最好的Frames Rate，且透過eXcelon技術，可以進一步消除波紋，提高靈敏度。

A measurement of the camera stability when no light hits the sensor.
A slope of zero would be ideal. See footnote #1.
A measurement of the stability of the electron multiplication applied to images. Ideal value would be 0. The stability of the EM gain applied can be quantified by measuring the slope of a sequence of images with known amount of light and EM Gain applied. See footnote #2.
|≤0.3 ADU/Frame (@ 10MHz, 350X, Gain State 2, 20K ADU)|
The image quality of the EMCCD is assessed for gradients. A complete lack of any gradient (i.e a flat image) would provide a numerical value of 1.00 See footnote #3.

|Baseline bias value||500ADU but can be varied|
|Cooling temperature||Air cooled (@ ambient air 20˚C) -85˚C|
|Dark current||0.0069 e-/pixel/sec (See footnote #4.)|
(10 MHz, 1000X EM gain) Standard operation
|Relative charge transfer efficiency
Photometrics is able to measure this on each camera and optimize this parameter.
|Optimized on each camera (See footnote #6.)|
|Charge transfer efficiency||As specified by CCD manufacturer’s data sheet (See footnote #7.)|
|Dark signal non-uniformity (DSNU)||As specified by CCD manufacturer’s data sheet (See footnote #7.)|
|Photoresponse non-uniformity (PRNU)||As specified by CCD manufacturer’s data sheet (See footnote #7.)|
|Parallel shift rate||100 ns. This is optimized with Charge Transfer Efficiency (CTE) and CIC. Test results demonstrate that increasing parallel shift rate further can decrease CTE and increase CIC, adversely affecting image quality and sensitivity.|
