Neutral Density Filter
Neutral gray-scale filter is a non-selective filter, that is, ND mirror for a variety of different wavelengths of light to reduce the capacity is the same, uniform, only to weaken the role of light, a...
Analysis of Optical Lens
From 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...
Grinding Technology and Classification of Optical Lens
In 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...
Different Types of Filters
Small and tiny though a filter is, it plays a vital role. As a part of the optical industry, filters play a key role. So what kinds of filters are there according to the spectral characteristics?1. Lo...
Classification of Optical Lenses and Their Functions
Optical glass refers to glass that can change the direction of light propagation and can change the relative spectral distribution of ultraviolet, visible or infrared light. Optical lenses are made of...
Classifications of Filters
Although there are many types of filters, they all have the same basic function: transmit light of a specific wavelength or color range while preventing the remaining wavelengths from passing through....
