1. 什么是中性密度滤光片？
中性密度滤光片让摄影师非常容易地控制图像中的曝光。该滤光片阻止光线到达相机传感器，因此我们可以让相机在更长的时间内保持更大的通光孔径。
2. 中性密度滤光片的用途是什么？
标准摄影中性密度滤光片的目的是减少光量进入镜头。这样做允许摄影师选择光圈，曝光时间和传感器灵敏度的组合，否则会产生过度曝光的图像。

长波通滤镜
长波通滤镜
长波通滤光片适用于各种应用，如气体监测，温度，传感，热成像和运动传感等。长波通滤光片可阻挡较短波长并传输较长波长。 阻挡可以来自反射，吸收或组合。 带通中的透射可以通过第二表面上的增透膜涂层来增强。
BK7和熔融石英玻璃道威棱镜
道威棱镜由H.W.多芬发明，多芬棱镜也被称为反转棱镜。当棱镜绕其长轴旋转时，通过棱镜所看到的图像的旋转速度是棱镜旋转速度的两倍。道威棱镜比较特殊，有时用于特殊的应用。入口和出口表面都有防反射涂层
激光等级透镜
激光透镜用于在各种激光应用中聚焦来自激光束的准直光。激光透镜包括一系列透镜类型，包括平凸透镜，激光划线透镜或激光发生器透镜。 激光头设计用于根据透镜类型以几种不同的方式聚焦光线，例如聚焦到一个点，一条线或一个环。许多不同的镜头类型可用于各种波长。
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.

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.
