Technical Description

(1) The cage system beam trap is a standard laser safety device in laboratories, usually used as the end component of an optical system. It handles continuous-wave (CW) laser beams up to 80 W. Simply align the beam to enter the SM05-threaded input aperture directly. It is compatible with Ø1/2-inch sleeves for beam path shielding and works with 30/60 mm cage systems.

(2) The CBT30 model can be directly inserted into a 30 mm cage system. The CBT60 model attaches to any two adjacent cage rods in a 60 mm cage system via a bend clamp and locks in position by tightening the screw.

(3) An M4 threaded hole on the bottom of the beam trap allows post mounting for use in free-space systems.
