A.2 External Digital PSV-A-515 Video Camera
A.2.1 Introduction
The video camera is a digital high-resolution video camera that can be used
instead of the video camera installed in the scanning head. The external video
camera allows a higher accuracy in the positioning of the laser beams for
VideoTriangulation. The video camera is monochrome, to get the best
possible resolution for this application.
By default, the video camera is provided with a prime lens (standard lens). As
an option, there is a 10x zoom lens available that is set up manually. For short
stand-off distances (180 – 300 mm) the zoom lens contains a close-up lens
that has to be removed for larger stand-off distances.
The zoom lens is delivered with the PSV-A-455 helium-neon block filter. If the
intensity of the laser light is still too high, it can be mounted additionally. The
block filter reduces the intensity of the laser light scattered back to the video
camera by 98%.
INFORMATION
With PSV-500 Xtra, the block filter has no effect. When required, reduce the
brightness of the pilot laser in the PSV software.
To position and align the external video camera you can optionally use the
VIB-A-T05 tripod with geared head.
ATTENTION!
Damage to the camera chip caused by skin contact !
The acidic protection layer of the skin consists of a hydrolipid film. If the
camera chip gets into contact with this film, i. e. if you touch it with bare
fingers, the chip becomes unusable.
» Do not touch the camera chip during assembly.
