OPTICAL SPECIFICATIONS: Features a 650nm narrow-band filter for precise light filtering and selective transmission of specific wavelengths 1PCS/Package
A filter is an optical component used to selectively control the transmission of light. Filters are usually made of plastic or glass substrates with special dyes added. The dyes change the molecular structure and refractive index of the materials. For example, a blue filter absorbs red and green light and only allows blue light to pass through
This series sells 650nm wavelength red light filtering optical lenses, which allow visible light to pass through while filtering out invisible light
There are two types available: round and square. The size parameters of the lenses can be found in the options. Please confirm that the size you choose matches your project before purchasing
We can offer customized services. If you have any customized needs, please let us know before purchasing
