1.什么是熔融石英玻璃?
熔融石英或熔融二氧化硅是由二氧化硅组成的非晶态玻璃。它与传统玻璃的不同之处在于不含其他成分，通常被添加到其他玻璃中以降低熔点。因此，熔融石英具有较高的工作温度和熔点。
2、优恩立光电能提供哪些熔融石英材料?
有许多公司提供熔融石英材料，如Corning，Heraeus，Schott，Nikon NIFS和Ohara;优恩立光电能根据设计生产熔融二氧化硅产品，包括Corning7980、7979、7978、Heraeus Spectrosil 200、HOQ310、Suprasil 300、JGS2、JGS2、JGS3等
3. 熔融石英玻璃的应用？
熔融二氧化硅及二氧化硅玻璃的属性。熔融二氧化硅是二氧化硅(石英、沙子)的一种非晶(玻璃)形态。它是典型的玻璃，其原子结构缺乏长程有序。它具有高度交联的三维结构，使用温度高，热膨胀系数低。
4.能用石英做玻璃吗?
首先，简单介绍一下背景，实验所用玻璃之可以经受极高的温度和极度的化学反应，因为它是由熔融石英制成的。同样的，这种材料实际上是纯二氧化硅，也就是石英晶体，这意味着要把它制成测试所用试管，必须要有极高的温度。
5.熔融石英是怎样制成的?
熔融二氧化硅(也称为合成熔融二氧化硅)是由富含硅的化学前驱体制成的，通常使用连续火焰水解过程，其中包括硅的化学气化、这种气体氧化成二氧化硅，以及由此产生的粉尘的热熔(尽管也有替代方法)。

分光五角棱镜是通过在棱镜其中一个倾斜面上添加一个楔，并加上部分反射涂层，可以将五角棱镜用作分光镜，透过率/反射率(T/R)比为50/50，其他比例的分光五角棱镜也能根据您的要求定制。
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.
