A bandpass filter is a relatively inexpensive type of optical filter used as a wavelength selector that allows transmission of a predetermined wavelength while rejecting or blocking other wavelengths.

Applications for a bandpass filter include, but are not limited to:

• Clinical chemistry instrumentation
• Environmental testing
• Colorimetry
• Elemental and laser line separation
• Flame photometry
• Fluorescence
• Immunoassays

Along with our wide selection of standard bandpass filters, we design and manufacture optimized solutions for instrument manufacturers world wide.
