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
Terms related to Optical Filters1) Central wavelength (CWL): The wavelength used, such as the main peak of the light source is 850 nm led lamp, requires a central wavelength of 850 nm.2) Transmittance (T): Assuming that the initial ...view
What are the Uses of Optical Filters?Optical filters are a relatively unfamiliar concept for many people. They seem to be a little far from our daily life, but they are not. Looking closely at the surroundings, we will find that many asp...view
Differentiation between Doublet Lens and Ordinary LensDoublet lenses are the most commonly used optical materials with mature manufacturing technology and complete varieties. Generally, doublet lenses can transmit colored light with wavelengths ranging f...view
Manufacturing Method of Doublet Lens Curing TechnologyMore than 30 years ago, ultraviolet (UV) light was successfully applied in commercial applications. Various adhesives manufacturers have developed a series of UV products for bonding, sealing, printin...view
