Cost-effective, different specifications, prices are different.
1. The protection of the lens as a major not to change the beam characteristics, high stability and unimpeded to allow the beam through, so that light from one environment into another different environment. Such as from air to water, or from vacuum to air, or from one environment to another, such as different temperatures, pressures, chemical composition, or cleanliness.
2. Protect both sides of the lens are precision polishing, is the λ / 10 surface accuracy and 5 seconds parallelism. Can be used for UV, visible and near infrared. Manufacturing protection of the lens Division I fully consider the material through the transmittance, uniformity, sub-surface defects, surface accuracy, parallelism; in the grinding process, to achieve a high transmittance, wavelet difference and low scattered.
3. Fiber laser protection lens and the ordinary anti-reflective film with the protection of the film, an increase of laser endurance, anti-laser film, high anti-reflective film, high temperature film, high damage threshold film.
