Spherical lens introduction, how to choose a single spherical lens Scoreboard gun aiming manufacturer?
Spherical lens is mainly divided into three structures: supply plane, concave and convex. The base materials include n-bk7, UV fused quartz, n-sf11, zinc selenide, calcium fluoride and silicon. Broadband antireflective films can be used in ultraviolet, visible, near-infrared and mid infrared bands.
Single spherical lens: spherical lens means that at least one of the two surfaces of the lens is a spherical surface, and the other surface can be a plane or a spherical surface. A single lens is a lens consisting of only one piece of optical glass. At the same time, the single spherical lens has these two characteristics.
How to select a single spherical lens Scoreboard gun aiming manufacturer?
1、 According to different materials used, single spherical lens can generally be divided into the following types:
1. N-BK7(350nm-2.0 μ m)Scoreboard gun aiming manufacturer
2. UV Fused Silica(185nm-2.1 μ m)
3. N-SF11(420nm-2.3 μ m)
4. CaF2(180nm-8 μ m)
5. BaF2(200nm-11 μ m)
6. Si(1200nm-8 μ m)
7. ZnSe(600nm-16 μ m)
8. Ge(2 μ m-16 μ m)
9. MgF2(200nm-6 μ m)
Each material has its own unique working wavelength range. Scoreboard gun aiming manufacturerAccording to the wavelength range, you can know what kind of lens material you need.
