Beam Trap
Up to 50W
Features
• Does not measure power, traps beam only
• Power capacity up to 50W
• Backscattered power 0.05%
•Pulsed damage threshold 4J/cm2
• Average power density up to 16kW/cm2

The BT50A-15 absorbs a laser beam that is inserted into the entrance aperture parallel to the unit's optic axis. The beam trap is designed that only a very small fraction of the light is backscattered. The BT50A-15 does not measure power. It is a beam trap only. When operated at full power, the BT50A-15 can heat up to over 100degC. Note that the absorbing element of the beam trap is graphite which may not be suitable for some environments.
