[Discotinued] Evolve® 512 > Photometrics

 Features

 Quant-View®

 Maximizes quantitiave measurements by converting intensities to the number of
 photo-electrons measured at the sensor.

 Background Event Reduction Technology®

 Improves image quality by removing spurious single-pixel events. The threshold is  software controlled.

Bias Stability

A measurement of the camera stability when no light hits the sensor.                    ≤0.001 ADU/Frame
A slope of zero would be ideal. See footnote #1.

Linearity                                                                                  >99%

Field Uniformity
The image quality of the EMCCD is assessed for gradients.                                 20 MHZ EM                   1.065        

 A complete lack of any gradient (i.e a flat image) would provide                           10 MHZ EM                   1.003

 a numerical value of 1.00 See footnote #2.                                                         5MHz                            1.012

                                                                                             .6?25MHz                         1.008

Stabilized Cooling Temperature                             Air cooled (@ ambient air 20˚C) - Standard                   -75˚C

?                                                                      Liquid cooled (@ ambient air 20˚C) - Optional               -75˚C

Dark Current                                                                                                0.003 e-/pixel/sec (See footnote #3.)

Background Events
(20 MHz, 1000X EM gain) Standard operation                                                     0.002 events/pixel (@ 1000X EM gain)

Parallel Shift Rate
The shift rate is optimized for maximum frame rates                                              0.200 mseconds

while providing extremely high charge transfer efficiency

 and minimal generation of clock-induced charge

Triggering Modes                                                                      Trigger first
Hardware triggering enables synchronization between                                        Strobe

many different system components. All triggering modes                                      Bulb

 are supported in overlap and non-overlap                                                        SMART Streaming (See footnote #5.)
