The effective focal length and back working distance of the system are respectively 100 mm and 113 mm, while the F number is 2.0.The system which has only three lenses contains two negative germanium lenses and one positive zinc selenide lens. 该系统全视场为14°,有效焦距为100mm,后工作距为113mm,F/2.0.系统采用锗和硒化锌两种材料,为三片镜结构。
In this system, two materials of Zinc selenide and Germanium are used, and the image quality of the system achieves diffractive limit at the temperature ranging from-20 ℃ to 60 ℃, with a compact structure and light weight. 该系统使用硒化锌和锗两种红外材料,在-40~60℃的温度范围内的成像质量接近衍射极限,并且体积小、结构简单,重量轻。
Study of Zinc Selenide Based Pigments 硒化锌基颜料的研究
The optical properties of zinc oxide and zinc selenide nanotubes are independent of diameters and chirality also. 不同管径和螺旋度的氧化锌、硒化锌纳米管也具有相似的光学性质。
Zinc oxide and zinc selenide nanotubes are direct band gap semiconductors and the gaps are independent of diameter and chirality. 氧化锌、硒化锌纳米管都是直接带隙的半导体,而且这种带隙不会随管径和螺旋度的变化而变化。
Zinc oxide and zinc selenide nanotubes show different properties from carbon and boron nitride nanotubes. 氧化锌、硒化锌纳米管显示出和碳纳米管、氮化硼纳米管不一样的特点。
The vanadium oxide thin films are prepared on zinc selenide by DC magnet sputtering method. The X-ray photoelectron spectroscopy ( XPS) test and data fit are performed and the components control in the films is realized by annealing. 在硒化锌基片上制备了氧化钒薄膜,对薄膜进行了X射线电子能谱测试和数据拟合,并对其进行了退火处理来调节薄膜内组分。
It is found that the stain energies of zinc oxide and zinc selenide single-walled nanotubes are lower than those for single-walled carbon nanotube and boron nitride nanotubes, indicating that the zinc oxide and zinc selenide single-walled nanotubes can be existent under certain conditions. 发现氧化锌、硒化锌的卷曲能比已被实验证实稳定存在的碳纳米管、氮化硼纳米管的卷曲能要低,这说明了氧化锌、硒化锌单壁纳米管在一定的实验条件下是可以存在的。
