Bandpass filters have a transmission band surrounded by two cut-off bands. They only allow a portion of the wavelengths in the spectrum to pass through. They are often used to transmit a portion of the spectrum while blocking all other wavelengths.
We offer a large number of standard filters in stock, with various specifications in stock.

Bandpass filters are suitable for a variety of applications, such as spectroscopy, clinical chemistry or imaging. Filters with narrow bandwidths (<20NM) are often used in elemental and chemical analysis applications, analytical instruments and laser cleanup. Wide bandwidths (>20NM) are often used in imaging applications, including fluorescence microscopy, machine vision and factory automation.
AOS Optics offers a variety of half-bandwidth bandpass interference filters with a variety of transmittances and sizes for you to choose from. We not only offer a large number of standard filters in stock, but also can customize filters for you according to your needs.
