Notch Filter It is a filter that attenuates light of a specific wavelength to a very low level and transmits light of [...]

Cold Mirror Direct cold illumination without heat to particular areas

Hot Mirror Visible wavelengths pass through while rejecting IR wavelengths, which produces heat and causes applications that are sensitive to heat.

Dichroic Filters Dichroic filters are a sort of filter that reflect certain wavelengths while transmitting others.

Short Wave Pass Filter (SWP) Reject long wavelength while pass all the shorter wavelength filter

Long Wave Pass Filter (LWP) Longwave pass filter (LWP), rejecting shorter wavelengths while passing all longer wavelengths

SWIR Bandpass Filter Designed to pass short-wave infrared (SWIR) wavelengths while blocking visible light, it is ideal for increasing the image quality [...]

NIR Bandpass Filter NIR bandpass filters SP are used in various optical sensor applications. They block the visible ambient light on one hand [...]

Narrow Bandpass Filter The Fullwave Half Max (FWHM) of a narrow bandpass filter is less than 10 nm, making it a sort [...]
