OPTOMAN designs, develops and manufactures advanced, high accuracy and repeatability thin film coatings by ion beam sputtering (IBS) technology. By concentrating solely on IBS, OPTOMAN is capable of manufacturing large diameter (up to 420 mm) laser optics that feature low absorption and scattering losses and high laser-induced damage threshold in spectral range from 193 nm to 5000 nm. For mirrors, high reflectivity (up to R > 99.99%) and for anti-reflective coatings, high transmitivity (R < 0.05%) are feasible.

The Future Depends on Optics

Edmund Optics offers an extensive selection of large diameter optics including achromatic lenses or aspheric lenses. Many of Edmund Optics’ lenses are offered with a variety of coating options for the ultraviolet (UV), visible, or infrared (IR) spectral range.

Hangzhou Shalom EO offers a diverse collection of large diameter optics, with a diameter range of 0.2 mm – 300 mm. With cutting-edge crafts, Shalom EO is capable of providing different types of optics including optical lenses (ball lenses, aspheric lenses, etc.), optical mirrors, high-power laser mirrors, optical windows, infrared domes of large sizes at a maximum of 300 mm, accommodating to an extensive range of requirements. A large amount of stocked and custom optical components with various dimensions, shapes, coating wavelength ranges, and specifications are available.

All the optics will go through in-process inspections during the production course and further tests in our class 1000 clean room before despatch to ensure the parameters of optical components meet or exceed the published specifications. Utilizing top-tier metrological instruments such as Zygo interferometers, and PerkinElmer Lambda 1050+ spectroscopes, Shalom EO secures the persistent reliable quality of our optical components.

YOUR KEY to innovation and success

A typical application of large aperture optics is in high-power/high-energy hertz (Hz) repetition rates systems for electron acceleration and high-field science. Here, the ability of the optics to withstand high average powers/energies is a pivotal requirement.

UFI’s optics have been tested to withstand up to 90 J/cm² energy density.
