Thorlabs BT600 Beam Trap 200nm To 3µm CW 80W 150W cm² 30mJ cm² ø11mm

Description:

The Thorlabs BT600 Beam Trap is used in laser safety systems to safely absorb and dissipate continuous-wave (CW) laser beams while minimizing backscatter in optical laboratories and industrial laser applications. Commonly installed in optical benches, laser research laboratories, photonics laboratories, semiconductor manufacturing equipment, laser alignment stations, and scientific instrumentation utilizing visible, ultraviolet, and near-infrared lasers. Optical engineers, laboratory technicians, and system integrators use this beam trap for laser safety, optical system termination, laboratory setup, and replacement of damaged laser beam absorption devices.

Applications:

The Thorlabs BT600 beam trap is designed to terminate continuous-wave laser beams by safely absorbing optical energy while reducing reflected and scattered light. It is widely used in laser alignment systems, optical research laboratories, spectroscopy equipment, interferometers, metrology systems, semiconductor inspection equipment, and photonics test benches where safe beam termination and low backscatter are essential.
