Specialised develops optical trigger

A Specialised Imaging product story
Edited by the Engineeringtalk editorial team Feb 6, 2009

Specialised Imaging has announced an optical trigger for use as a general-purpose optical detector, to detect a very bright flash of light or an object moving across its field of view.

Robustly designed, the OT-2 optical trigger is aimed at the outdoor market.

Employing the combination of a multi-segment photodiode array coupled with high- and low- pass filtering results in a highly reliable trigger that is sensitive from 300nm to 700nm.

The OT-2 is battery-driven, so is immune from electrical noises produced when a gun is fired or other high-voltage instrumentation is triggered.

Unlike a traditional skyscreen or muzzle flash detector, it has a viewfinder that allows the user to accurately focus on the point of the bright flash or where the projectile/object passes its active area, allowing for more accurate and less false triggering.

Providing reliable detection of projectiles greater than 0.7mm in diameter, the OT-2 optical trigger offers the option of interchangeable objective lenses to ensure at least 1/20 obscuration of the field of view.
