Optical filters selectively transmit light with certain properties, while simultaneously blocking remaining light. Filters are utilized for color separation in CCD imaging, machine vision, digital projection and photographic applications.
There are several types of Optical Filters:
 |
- Absorptive Filters absorb specific wavelengths of light while transmitting others
- Reflective Filters reflect the undesired wavelengths while transmitting the remaining ones
- Monochromatic Filters allow a limited range of wavelength to pass
- Neutral Density (ND) Filters are utilized to reduce the intensity of light by reflecting or absorbing a percent of light at specific wavelengths
