Optical mirror
Optosigma Corporation
* Designs for tunable and white-light applications
* Polished to λ/10 minimizing subsurface structure
* ≤ 3 arcmin parallelism
* 30-100 dielectric layer designs for high reflectance
* Designed for 45 degree angle of incidence
* Standard diameters from 12.7 to 50.8mm
These mirrors have the same exceptional specifications as our laser mirrors except that they use special multilayer coatings to achieve a very high degree of reflectance for both s- and p-polarizations over a broad wavelength range. For white light or tunable laser use these mirrors provide the ultimate in high reflectance and insignificant polarization effect.
The reflectance of these coatings is consistently greater than 99.5% average. However, this figure includes very small dips in the p-reflectance which can never be completely eliminated. The s-polarization component has a reflectance greater than 99.9% over the entire range.
