Quartz glass and quartz components

for optics, laser and medical technology, industry

FRANK OPTIC PRODUCTS® primarily provides customerspecific plano optical precision components made from quartz glass and natural and synthetic quartz crystals, also oriented and random with customer-specific AR or HR coatings, manufactured to meet your individual requirements by means of different processing techniques. Frank Optic Products is the OEM (Original Equipment Manufacturer) for leading laser manufacturers because of its great reliability and precision. Especially when it comes to laser windows, flow plates, flow tubes, fibre optic beam delivery systems and reflectors they place their trust in the profound experience of Frank Optic Products®.

Quartz products for industry and research

FRANK OPTIC PRODUCTS® supplies quartz products in any desired configuration, such as: flat windows, prisms, (sample) slides, lenses, rods, tubes, fibres, moulds and substrates for optics, laser and medical technology, laboratory and equipment technology, the chemical industry, aerospace, light design, mechanical engineering, special engineering and R&D. Quartz is used for optical purposes because of its large transmission range and its high melting point and double refraction.
