Mirrors are available in a range of shapes and sizes, have high reflectivity, a broad spectral range and are low polarizing (10000:1) enhancing contrast while minimizing glare. Custom optical mirrors can be designed with a variety of reflective coatings, including multi-layers, enhanced aluminium or protected silver, gold and dielectric.
