OFL244 Infrared Illuminator
This 200mW 808nm laser has been used by by many customers for night vision applications since the variable focus allows the beam to be adjusted from a small intense spot up to a large rectangle. The beam is 'letterbox shaped' as shown in the photos below, this is a feature of higher power infrared laser diodes.
The laser can be used either with 2 x CR2 batteries for the highest output or with 1 x 14500 battery for a slightly lower output but extended run-time.
Night Vision Applications
This laser has been used by a number of customers as an illuminator for night vision applications particularly for hunting in conjunction with a Sony camcorder that has an IR mode attached to a day scope.
'Snypercat' (YouTube) was one of the first people to use the Sony camcorder with a scope for night vision and has kindly posted a review of using the OFL244 IR Laser Illuminator with her night vision system on YouTube. Below are a series of stills from the clip showing how it functions:
