Where to Buy Supermirrors

OPTOMAN's extremely low-loss mirrors have a maximum reflectivity of R > 99.998% and total losses (absorption, scatter, and transmission) below 15 ppm at a discrete wavelength and angle of incidence. Coatings are applied on high purity fused silica substrates (plane, spherical or wedged) super-polished to an RMS roughness of <2 Å. Mirrors are available with a CRD measurement that prove reflectivity and loss values.

Thorlabs manufactures high-performance, single-crystal supermirror coatings on Ø1" substrates for applications requiring the highest reflectance possible at a specific wavelength. These high-performance supermirrors with ultralow optical absorption and minimal Brownian noise are key ingredients for the construction of optical atomic clocks, optical reference cavities, and stabilized lasers, as well as the next generation of gravitational wave detectors.

UltraFast Innovations (UFI) offers supermirrors with a reflectivity exceeding 99.99%. Our magnetron sputtering facility offers the best technology for ultra-high reflection mirrors due to the extremely dense layers. More than 99.997% reflection over a bandwidth of 200 nm or more is achievable.

Characterization of these mirrors is performed in a cavity ring-down measurement device with ppm-level precision.

So-called supermirrors for ring laser gyroscope assemblies or certain scientific applications require coated optics with extremely low losses (i.e. absorption and scattering). These mirrors also have a maximum reflectivity with R > 99.998% and total losses < 10 ppm.

LASEROPTIK uses a modified IBS machine that is capable to produce coatings on super­polished substrates. The cleanliness of the machine and environment is maintained in a dedicated super-clean room, where also the extensive substrate pre- and after-treatment takes place.

Measurement devices such as whitelight profilometers and high resolution microscopes (up to × 1000) for the inspection procedures are in place. A custom built cavity ring-down setup allows to determine the reflection with a precision of up to four decimal places and to refer back to the losses.
