Buy Optical Filters Online: Bandpass Filters, IR Cut Off Filters, Dual Bandpass Filters, and Custom Filters.
Optical filters are glass windows that transmit or block certain wavelengths. Optical filters are made with absorptive glass or reflective thin film interference coatings, or a combination of both coatings and glass material.
Filters are used in industrial machine vision to increase the contrast of certain colors, making it easier to identify, characterize, and classify specific objects.
Bandpass filters and dual bandpass filters are used in surveillance and robotics navigation systems to enable infrared illumination to be observed..

Types of Optical Filters
- Bandpass filters pass light in specified wavelength range(s) and block other wavelengths.
- Edge filters play a role in wavelength-dependent reflection and transmission, fitting into the broader category of interference-based filters.
- Longpass filters pass light above a cut-on wavelength and block light below this cut-on wavelength.
- Shortpass filters pass light below a cut off wavelength and blokc light above this cut-off wavelength.
- Notch filters: Block specific wavelengths and pass others. These are similar to bandpass filters, but can have multiple blocked wavelength ranges.
