Product Name Notes
Bandpass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. As one of the best optical bandpass filter manufacturers, we can...
Based on the technique of all-dielectric hard coating and the principle of dielectric interference, and based on the characteristics of narrow-band filters, the optical properties are independent of the substrate.
Infrared cut filter is the use of precision optical coating technology on optical substrate plating alternately high and low refractive index of optical film, achieve high visible light area (400-630...
Neutral density filter is often used in imaging or laser applications to avoid strong light damage to camera sensors or other optical components. ND filters absorb or reflect untransmitted light...
One side is coated with a hard dielectric long-pass optical filter film, and the other side is coated with an anti-reflection film to achieve high transmittance and high damage threshold.
The optical glass filter is an optical device used to select the desired radiation band. One of the common characteristics of filters is that there is no filter to make...
