Image quality at 1064nm	Pulsed with video trigger - good Pulsed, synched - excellent CW - good
Operation mode	Interline transfer progressive scan CCD
Software supported	BeamGage
PC interface	IEEE 1394b Firewire
Minimum host system requirements	IEEE 1394b requires 1394b port or PCI-Express or CardBus Slot

Camera set to full resolution at maximum frame rate and equivalent exposure times, running CW at 632.8nm wavelength. Camera set to minimum useful gain for saturation test and maximum useful gain for lowest signal test.
The maximum rate depends on the ROI (Region of Interest) size, the bits readout, and the number of cameras on the same bus. The SCOR 20 operates at 7.5Hz 12 bits and 15Hz 8 bits. It operates up to at least 60Hz with a smaller ROI. The frame rate also depends on PC resources
May be usable for wavelengths below 350nm but sensitivity is low and detector deterioration may occur. Therefore UV image converter is recommended. For operation at 1300nm sensitivity is low and short wavelength blocking filter SPZ08242 is recommended.
This is the damage threshold of the filter glass of the filters. Assuming all filters mounted with ND1 (red housing) filter in the front. Distortion of the beam may occur

Cameras are part of a Laser Beam Analysis System
The camera and software are sold as a package
