Bandpass Filters with Size (mm) 12.5 mm dia.

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.
