Do you know the use of optical flat window mirror
Optical level plane window slice is mainly used for:
1 The lens is generally used outside the lens zui to protect the internal optical system without affecting the overall performance. The thickness is generally 2-5mm, and the aperture size depends on the lens size. The common materials for visible light are K9, quartz and calcium fluoride are used for near ultraviolet, and zinc selenide is used for infrared;
2 Laser protective lenses, which are widely used in the laser industry, are also consumables. They are used to protect the inner group of the mirror and the mirror field mirror from external dirt and collision. Especially in laser welding and laser cutting, the inner part of the mirror group is protected from debris damage. At present, there are many varieties and specifications required in the market, and the requirements for laser damage resistance are different. The main materials used are K9, quartz, and precious stones, Zinc selenides;
3. It can be used in optical systems for light splitting and reflection. After optical coating, it can be used as spectroscopic lens and reflective lens;
4.Ultra thin lenses have been used more and more in recent years, mainly for medical treatment, chips, solar energy, etc., with a thickness of 0.1-0.2mm;
5. For standard tools, the thickness tolerance required for such lenses is generally 0.001-0.002mm, and the surface type is usually one tenth to one twentieth of the wavelength. At present, our company provides many quartz materials;
