The Introduction of Bandpass FilterA bandpass filter is a filter that can pass the frequency component within a certain frequency range but attenuate the frequency component of the other range to a very low level. An example of analog ...view
Aspherical Lens are Lighter, Thinner, FlatterThe spherical lens is with a constant curvature from the center of the lens to the edge, while the aspherical lens changes continuously from the center to the edge. In photographic lenses, many aberra...view
Cold Processing Procedure of Optical LensThe first way: milling, is to remove the uneven surface of optical lens bubbles and impurities, (about 0.05-0.08) play a forming role.The second process is to eliminate the damage layer of the milling...view
New Applications of Optical Lens BondingOptical manufacturers usually use mercury lamp UV ovens when they glue lenses to lenses. Now most optical factories have realized the concept of environmental protection and energy saving, as well as ...view
Grinding Technology and Classification of Optical LensIn the process of plane planetary lapping, the uniformity of lapping disc wear is closely related to the lapping quality of optical lens. Based on the analysis of the motion law of optical lens in pla...view
Analysis of Optical LensFrom the word light alone, we can see that it means bright and transparent. Optical lenses must have these attributes and have good transparency.Optical lenses are highly transparent, chemically a...view
What is a Bandpass Optical Filter?In a certain band, there is only a small band with high transmittance in the middle and a high reflectivity cut-off band on both sides of the band. This kind of optical filter is collectively called b...view
What are the Optical Glass Substrates for Filters?Optical glass substrates of optical filters mainly include absorption glass, such as JB510, CB535, HB850, colorless optical glass K9, float glass, B270, fused quartz, etc.Geometric dimensions and thic...view
