Howell CMOS Image Chip Industrialization Project was started in Songjiang, Shanghai, to build a wafer filter and microlens packaging production line On June 16, Haowei
Introduction to the classification of filters A filter is an optical part that attenuates light intensity, changes spectral composition, or limits the vibration surface. As
Filter is an optical device used to select the required radiation wave band. A common feature of filters is that no filter can make the
The plane reflector of the projector is made of polished flat glass bricks and vacuum coated. Special attention should be paid to maintenance. The plane
Laser lens plays an important role in the laser system. The change of laser light path is realized by the refraction of the lens. Function
Infrared spectroscopy is an important means to analyze the structure of compounds. The conventional transmission method uses tablet or coating to measure, and it is
In 1611, German astronomer Kepler first used two biconvex lenses as objective lens and eyepiece respectively, which significantly improved the magnification. Therefore, later generations called
Achromatic doublet glued lens is an optical design that combines two single lenses. The two lenses are made of glass with different refractive index and
Is the lens focal length the same as the camera focal length? Because the shorter the focal length of the convex lens, the greater the
Color filter is an optical filter that represents color. It can accurately select the light wave in a small range to pass through, and reflect
