The Survelase is a long-distance targeting laser diode module that produces a small well-defined spot up to 140m away. The high quality output beam afforded by the Survelase is beneficial in range-finding, positioning, surveying, or general measurement applications involving large working distances.
Wavelengths of green (520nm) and red (635, 650nm) are available with output powers up to 5mW. The green model emits light that appears more than 2X brighter to the human eye than the equivalent power in 635nm. As a result, you’re more likely to see these projections against dark materials or in high ambient light levels (e.g. daylight).
The Survelase can optionally be installed with a TTL modulation input allowing you to drive your laser using a digital voltage signal. You can then change the mark-to-space ratio to control the mean intensity of the output beam, modulate the laser with coded information, or synchronise the laser with an external measurement device such as a photodetector or camera.
A user-adjustable focus is another optional feature of the Survelase. A focus key (purchased separately) allows you to focus the laser as required in your application without removing the internal collimating optic or exposing the raw laser beam. This provides flexibility, ease-of-use, and allows you to maintain the specified laser classification.
