optical density filter
Description
The optical density filter is a translucent material used to attenuate the intensity of light passing through it. An optical density filter absorbs or reduces the amount of light that passes through, depending on its composition and transmission characteristics.
It is a piece of equipment that blocks all visible light but lets infrared light pass through. It can be used to measure the type and quantity of color additives in foods or to measure the level of alcohol in the blood. The glass used to make an optical filter is very thick so it blocks out more light than other types of glass.
This optical density filter blocks most visible light, making it ideal for use in situations requiring low-light sensitivity, increased contrast, and deeper red sky colors. The filter is compatible with all photography equipment, including DSLRs, digital backs, and medium format cameras.
We are an optical density filter factory in china.If you need optical density filter.please feel free to contact us.
Intelligent Identification Filter
We are an optical bandpass filter manufacturer in China. Our optical filter is one of the precision photoelectric thin film components. Its main principle is to realize the high transmission or high reflection effect of a specific band light source through special optical design and help terminal products complete the extraction, screening, and transformation of biological information and the acquisition of 3D depth of field information.
