Product Portfolio
Within our range of optical mirrors, electrostatic driven MEMS micromirrors as well as magnetic actuated MEMS micromirrors for somewhat larger mirror diameters feature Aluminium (Al) or Gold (Au) surfaces.
For specific requirements, custom optical mirrors can be designed and manufactured exactly tailored to your application. Custom optical mirrors can be fabricated from a broad range of materials like various optical glasses as well as crystal materials, coated with metallic or dielectric reflective coatings or polarizing coatings.

Precision optics of this kind, manufactured and coated to very specific and demanding tolerances, is in great demand by our customers. Other available components that can be realized include optical windows, spherical lenses and molded glass aspheric lenses, cylindrical lenses, prisms or optical filters. All featuring high precision, smallest tolerances (dimensional and angular) and special coatings for exotic wavelengths, even into the UV spectral range.
Additionally, we carry a broad range of complementary products such as optical mounts, rotary and translation stages, optical tables, breadboards and platforms, as well as a broad range of optical test and measurement equipment.
Definition
Optical mirrors are designed to reflect light of specific wavelengths. In addition to broadband mirrors, there are also types that are optimised to reflect a specific wavelength or a narrow wavelength range with as little loss as possible – for use with laser beams, for example. Typical areas of application for optical mirrors are general optics and laser technology, but also astronomy, metrology, life sciences, semiconductor technology or solar technology.
How to Select Your Optical Mirror
Reflectivity:
A mirror’s reflectivity is defined as the part of the optical power incident on the mirror that is reflected by the mirror. To achieve the highest possible reflectivity, a substrate is coated with a reflective coating. Metallic coating (e.g. with silver, gold, aluminium, chrome/nickel or copper) achieves the widest wavelength range, and the reflectivity of this coating is relatively independent of the light’s angle of incidence and polarisation. Dielectric coating, on the other hand, which is usually done in several thin layers of dielectric material, defines a narrower spectral working range.
Shapes of Optical Mirrors:
Optical mirrors for professional use are mostly thin, circular or rather cylindrical components, but are also offered on the market in rectangular, elliptical or other geometric shapes. In the professional sector, first-surface mirrors are mostly used, where the light falls directly on the coating and does not pass through a transparent mirror substrate before being reflected (like the protective glass above the reflective silver layer of a conventional household mirror).
