OIS - Model 400-37 -Deep Sea Laser

Designed as a scaling device for video and digital cameras, the Ocean Imaging Systems Model 400-37 laser features a titanium housing and connector, sapphire optical port, and an adjustable “ball in socket” mounting clamp. Typically, two lasers (or optionally 4) are mounted and aimed to place two laser “dots” within the field of view of the camera, a known distance apart. The dots serve as a known reference for scaling objects within the image.
