OPTOMAN

High Reflectivity Mirrors

Overview

In space and defense applications, laser systems play a critical role in various areas, including communication and navigation. Extreme conditions require these systems and their components, especially laser optics, to feature high environmental stability and spectral performance OPTOMAN has developed application-optimized laser optics with increased longevity and LIDT, while maintaining low degradation. OPTOMAN’s laser optics not only survive the harsh space, but also thrive and showcase excellent spectral performance.

Key Problems

Short duty cycle and lifetime of laser optics caused by coating absorption and laser damage.

Beam profile deformation

Polarization sensitivity requires beam delivery components to be optimized for s and p at the same time.

Multiple wavelengths coverage in the system.

What can OPTOMAN do for the space and defence markets?

Enhanced lifetime, environmentally stable laser optics featuring excellent spectral performance.
