1 FLEXPOINT Machine Vision Laser The MVstereo (PRPG) projects a dot matrix of divergent dots. It is available with 660 nm and 830 nm. LASER COMPONENTS offers an eye safe version for each wavelength. The MVstereo PRPG lasers include our new digital laser driver which offers various programming and reporting features. A version in our standard 11.5 mm Ø housing without digital driver is available too. Applications 3D Stereo Machine Vision Gesture recognition Depth sensing Volume measurement Features Pseudo random dot matrix 660 nm or 830 nm Eyesafe Adjustable focus without removing the optics VDC supply voltage 19 mm industrial housing Microprocessor controlled 112/17 / V03 / IF / lasermodules/mvstereo Laser Components, Inc.

Analog power adjustment Output power can be adjusted to any desired value within the capabilities of the installed laser diode. Due to safety regulations and laser classifications, the maximum output power can only be set by the factory during manufacture. Please note: The maximum laser power is set during production; and the user can only reduce the laser power. This is locked via the firmware and password protected. When using analog power adjustment, there is a distinction between active high and active low Active high The output power of the laser is proportional to the input voltage. The input voltage can be set via RS-232 commands in the range 0 5 V Active low (default) Inverse power adjustment follows an opposite relationship to the input voltage. The following graph (fig. 1) shows this relationship: 412/17 / V03 / IF / lasermodules/mvstereo Laser Components, Inc.
