Shanghai Optics is a custom optics manufacturer with over 55 years of optics manufacturing experience. We produce high precision Broadband Dielectric Mirrors according to customer’s specifications.
These mirrors have the same exceptional specifications as our laser mirrors except that they use special multi layer 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.
