First, the appearance of the wrought iron gate is beautiful: With the continuous development of the society, people's appreciation level is getting higher and higher, and the artistic level of the wrought iron gate is gradually rising.
Second, the practical function of the wrought iron gate: the initial function of the wrought iron gate is still anti-theft, and now the functions are gradually diversified.
Multi-spectral grade of zinc sulfide has low absorption and scatter properties over its broad transmission range of 0.4 - 12μm. Zinc Sulfide Multispectral is a chemically vapor deposited material which is commonly used in thermal imaging. With its excellent transmission properties in the visible and infrared, Zinc Sulfide Multispectral is the material of choice for systems that have both visible and mid-wave or long-wave infrared sensors. It is slightly harder and more chemically resistant than zinc selenide.
We consistently offer various high quality optical components according to the customer's requirements use other infrared materials. Such as prisms,Spherical Lens, aspherial lens,Ball lens,Optical Windows,Achromatic Lens,cylinder lens etc.
