Thin Film Polarizers
Extintion ratio higher than 3000:1.
The most typical value of extinction ratio we find in the market is 200:1. OPTOMAN aims for much higher values and reaches contrast of more than 3000:1!
Angle of incidence 45°, 56°, 72°…
For effective and efficient adjustment OPTOMAN polarizers are designed at 45°. In this set-up laser beams are separated at 90°. For highest possible extintion rate we offer Brewster type polarizer, for ultrafast applications - at 72° angle.
Single wavelength and broadband polarizers within 350 - 1500 nm range.
OPTOMAN polarizers cover most popular laser lines from 350 nm up to 1500 nm. Broadband configurations for femtosecond applications are also feasible.
Reflectance Rs>99.95% and transmittance Tp>99% available
What matters the most in your application? Is it Tp transmittance or Rs reflectance? Or is it extinction ratio? OPTOMAN will optimize product exactly to your needs.
Laser damage threshold >20 J/cm2, 1064 nm, 10 ns, 100 Hz.
When polarizers are optimized for high damage threshold OPTOMAN assures >20 J/cm2 and >10 J/cm2 at 1064 nm, 10 ns, 100 Hz for s-polarized and p-polarized beams.
- Single wavelength and broadband polarizers with 350 nm up to 1500 nm range.
- Broadband configurations for femtosecond applications are also feasible.
- Custom shapes, size and material of substrate.
- Optimization for ultrafast applications.
