Discover the Off-Axis Collimator (COTOF)

No obstruction. No compromise. The broadest spectral freedom for your optical test bench — from lab to field.

Optical Testing Without Limits
The COTOF pushes the boundaries of what a collimator can deliver. Designed to perform across an adjustable spectral range with zero image quality trade-off, it adapts to your most complex test configurations — in controlled environments and under extreme conditions alike.
