Bandpass Filters are designed to transmit a portion of the spectrum, while rejecting all other wavelengths. These optical filters offer steep slopes with deep blocking to achieve high performance in demanding applications.

Contact us for working out a solution.

Bandpass filter transmits the lights of specific wavelength range only. The band pass filter is after used for optical telecommunication devices. 

We design the band pass filter corresponding to customer requirements such as center wavelength, FWHM and band width.

The design can be used to deposit into various types of optical materials, including plastics, molded polymer optics, glass substrates, fiber optic equipment, and crystal and semiconductor materials.

The design can be optimized from 200nm to 2000nm in broadband band wavelength or multi-band applications to ensure maximum system performance. Specify your specific wavelength range, incident angle, substrate material, and incident medium. Our design team will work with you to produce the best dieletric optical coating for your application.
