How this component is specified
Dielectric mirrors achieve high reflectance over a designed band. The coating is sensitive to wavelength, AOI and polarization, so the curve must be reviewed with the optical layout. Specify whether the mirror is used at normal or 45° incidence and whether laser damage is a requirement.
Typical applications
- Laser beam steering
- Interferometry
- Broadband reflection
Design options
- Dielectric HR coating
- UV fused silica or glass substrate
- Custom AOI and band
- LIDT review
