Manual, SP2 Beam Scan Camera and Software

The following is the listing of the mightex.prop file:

; gain is normally 1.0, but can be as high as 16

gain=1.0

; gamma is from 0.0 to 2.0

gamma=1.0

; contrast is from 0 to 100 in percent

contrast=50

; brightness is from 0 to 100 in percent

brightness=50

; exposure time is in microseconds, so 30000 us = 30 ms

; can be up to 750 ms (750000)

exposure time=10000

;

; the frame rate slows greatly at the higher exposure times. 750000

; is the maximum exposure time on the Mightex cameras. That should

; be enough to integrate multiple laser pulses if needed.

It is recommended that exposure time be lengthened until saturation happens. Then back off

the exposure time by 500 or 1000 units. Saturation will not cause damage to the camera, and it

can be useful to operate in this mode, as the base of the beam will be easier to visualize. No

studies have been done on modifying the other parameters in the mightex.prop file.

CAUTION: The Mightex camera is fitted with a 5 OD filter for standard operation. This reduces

the laser power to a range where the camera can provide a good beam profile. The laser power

that is available at the YAG power monitor can be up to 200mW. The Mightex camera is rated to

withstand laser power of up to a MAXIMUM of 70mW only under certain conditions, which are

unspecified. Operation of the camera on the SP2 with any neutral density filter having an OD of

less than 2 will void the warranty of the product. The Measured leakage should be between 80

– 100 mw
