Fiber Laser Cutting Head Collimating and focusing lens

Fiber Laser Cutting Head Collimating and focusing lens

The functions of the lens in the optical system are: focusing, collimating, and imaging. According to the surface type of the lens, there are: plano-convex, plano-concave, double-convex, double-concave, meniscus, cemented lens, etc.

The lens materials are: BK7, K9, quartz, germanium, silicon, zinc selenide, magnesium fluoride and other high-quality glass. The lens usually needs to be coated with anti-reflection coating to reduce the reflection on the surface of the lens. This can reduce the loss of light energy and make the image clearer.

Fiber optic collimating lens, fiber optic focusing lens

Focusing and collimating mirrors are used in related fields such as laser cutting machines, laser detection, laser welding machines and optical imaging life sciences. Objects burn or sublime rapidly for cutting and welding. The base material of the focusing mirror is quartz and K9 crystal, in order to meet customers with various needs, we have focusing mirrors with domestic materials (China) and imported materials (US).

The focusing lenses on the market are plano-convex and crescent lenses. Because the crescent lens has better focusing effect and the price is the same, we recommend using the crescent lens. For customers with special needs, we can also provide plano-convex lenses, bi-convex lenses, bi-concave lenses, plano-concave lenses,
