Interference Filters

Interference filter is a filter that transmits only the specific wavelength, and blocks its shorter and longer wavelength. It is based on the principle of the Fabry-Perot interferometer. MATERION Corporation (formerly BARR Associates Inc., USA) produces various filters in the wavelength range of 195nm ~ 50μm.

Glass Polarizers

As well as its high contrast ratios within the given spectral range, CODIXX colorPol® polarizers offer a very high transmittance and a low insertion loss. They are available for the spectral range of 340nm~5000nm. The silver nano particles in soda-lime glass substrates show strong plasmon absorption, which is selective in reference to polarization and wavelength.

With its unique diamond machining technology, KUGLER offers high-quality metal mirrors for laser products. KUGLER specializes in supplying components for CO2, fiber, and NdYAG lasers with a power range from 100 Watts up to highest powers of e.g. 60 Kilowatts.

Crystal for Laser

Raicol Crystals Ltd. (Israel) specializes in the manufacture of nonlinear optical crystals and electro-optic devices. Raicol's flux-grown KTP and RTP crystal products are world-renowned for their high quality and reliability. The company's innovative crystal growth technology ensures that customers receive robust and reliable Grey Track Resistant KTP elements for intra-cavity CW and high average power SHG @ 1064nm. Raicol has also developed growth technology for high quality LBO and BBO crystals.

Galvano Mirrors

MERSEN (formerly optoSiC) manufactures standard silicon carbide Generic 'one-size-fits-all' XY laser galvo scanning mirrors at 10, 15, 20 and 30mm apertures for single pair consumption with a range of reflective coatings. MERSEN also manufactures customer-specific OEM products within a single piece size of 680 x 300 x 50mm or ø300mm. These include ultra-high dynamic, low inertia scanning mirrors for laser processing, streak cameras, LIDAR, security, sensing and targeting applications, where the enhanced flexural strength, homogeneity, high resonant frequencies, ultra-low inertia, optical surface quality and realistic price to produce the optoSiC+ material are key. MERSEN also manufactures structural parts and cooling components from optoSiC+ material.

X-ray Optics
