Technical Specifications

 

The Ø12mm laser in the OM series uses original imported diodes, featuring small size, clear beam, large divergence angle, and high straightness. It is driven in constant power mode, with built-in photodiode feedback to maintain stable optical output power.

The focus knob on the laser head can be rotated left or right to adjust the focus according to the working distance, achieving the desired spot size easily and quickly.*Parallel beam spot: 3.5 mm within 1 m (beam spot on white viewing screen)

It can be installed on precision mirror mounts, SM1 lens tubes, and 30mm cage systems by using POL series laser mounting holders or OAD-F series adjustable collimation adapters, supplying the required light source and optical path for optical experiments.
