1、How do optical filters work?
Optical filters are passive devices that allow the transmission of a specific wavelength or set of wavelengths of light. Absorptive filters have a coating of different organic and inorganic materials that absorb certain wavelengths of light, thus allowing the desired wavelengths to pass through.
2、What is the central wavelength of a red filter?
Recall that the visible wavelength ranges are: 430 to 490 nm = blue; 490 to 530 nm = green; 530 to 580 nm = yellow; 580 to 630 nm = orange and 630 to 700 nm = red.

Machine Vision Bandpass Filters
A band pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range, and it’s used to selectively transmit a portion of the spectrum while rejecting all other wavelengths.
Longpass Filters for Vision inspection Apllication
Longpass filters are ideal for a variety of applications, such as gas monitoring, temperature, sensing, thermal imaging and motion sensing, etc. Longpass filters block shorter wavelengths and transmit longer wavelengths. Blocking can be from reflectance, absorption or a combination. Transmission in the pass band can be enhanced with an antireflection coating on the second surface.
Optical glass neutral density filters
A Neutral Density filter allows a photographer to control the exposure in an image very easily. The filter stops light reaching the camera sensor, therefore allowing us to leave the camera with a higher aperture for a longer amount of time.
