Uni Optics平凹圆柱面镜在垂直方向上具有凹面曲率，在水平方向上无曲率。它们边缘呈圆形，因此在光学系统中很容易与其他元件结合。
1. 为什么使用柱面镜？
柱面镜通常用于聚焦、凝聚或扩展入射光。柱面镜有一个柱面，使光聚焦在一个尺寸或轴上。
2. 使用圆柱面镜可以纠正眼睛哪些缺陷？
用柱面镜可以矫正眼睛的散光缺陷。散光是由于晶状体曲率不均匀造成。

2）保护性铝膜：从400nm到800nm的平均反射率> 87%
3）保护性银膜：从400nm到20um的平均反射率> 400%
4）保护性金膜：从650nm到16um的平均反射率> 98%
2，金属镀膜反射镜具有什么特点？
金属涂层镜具有以下特征：
光谱范围广
对入射角和偏振态不敏感
低成本
非耐用品
反射率相对较低
激光损伤阈值低
3，优恩立光电能为您提供什么金属镀膜反射镜？
常用规格：
基底材料：N-BK7，熔融石英，耐热玻璃，浮法玻璃
尺寸公差：+/- 0.1mm
表面质量：60-40
平行度：3'
平整度：λ/ 4 / 25mm @ 633nm

一个表面：抛光和金属镀膜
另一个表面：细磨
注：铝是最广泛使用的金属反射膜，从近紫外到近红外，具有高反射率，且成本低。银在可见光和近红外波长下的反射率高于铝膜，但空气中的银会快速氧化，颜色变暗，使薄膜性能和硬度迅速下降。金膜具有良好的一致性，在近、中、远红外范围内具有高反射率，可以有效控制热辐射，但它比较柔软，容易擦伤，应该非常注意清洁，而且成本很高。
N-BK7角锥棱镜
角锥棱镜又称反射镜，它有三个相互垂直的表面和一个斜边面。通过斜边进入的光依次被三个表面反射，并通过平行于入射光束的斜边面出现，而不考虑入射光束的方向。由于其特殊的性能，常被用于距离测量、光学信号处理和激光等领域。

红外材料
1. Germanium (Ge)
Germanium (Ge) is the preferred lens and window material for high performance infrared imaging systems in the 8–12 μm wavelength band. Its high refractive index makes Ge ideal for low power imaging systems because of minimum surface curvature. Chromatic aberration is small, often eliminating the need for correction.

2. Silicon (Si)
Silicon (Si) is grown by Czochralski pulling techniques (CZ) and contains some oxygen that causes an absorption band at 9 microns.To avoid this, material can be prepared by a Float-Zone (FZ) process. Optical silicon is generally lightly doped (5 to 40 ohm cm) for best transmission above 10 microns, and doping is usually boron (P-type) and phosphorus (N-type). After doping silicon has a further pass band: 30 to 100 microns which is effective only in very high resistivity uncompensated material.
CZ Silicon is commonly used as substrate material for infrared reflectors and windows in the 1.5-8 micron region. The strong absorption band at 9 microns makes it unsuitable for CO2 laser transmission applications, but it is frequently used for laser mirrors because of its high thermal conductivity and low density. Application as window, lens in the 1.5 - 8 um region; Mirror for CO2 laser and spectrometer applications.

3、ZnS material:
ZnS MultiSpectral Under intense heat and pressure, defects within the crystalline lattice are virtually eliminated, leaving a water-clear material with minimal scatter and high transmission characteristics from 0.4 to 12 microns.

4. ZnSe material
ZnSe is a preferred material for lenses, windows, output couplers and beam expanders for its low absorptivity at infrared wavelengths and its visible transmission. For high-power applications, it’s critical that the material bulk absorption and internal defect structure be carefully controlled, that minimum-damage polishing technology be employed, and the highest quality optical thin-film coatings are used. The material absorption is verified by CO2 laser vacuum calorimetry. Our quality assurance department provides testing and specific optics certification on request.
ZnSe is non-hygroscopic and chemically stable, unless treated with strong acids. It’s safe to use in most industrial field, and laboratory environments.
