Bandpass Optical Filters for Industrial Imaging

BP BROAD BAND SERIES BANDPASS FILTERS
Designed to test the effects of monochromatic illumination, these filters have a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths.

• Blocks interfering wavelengths which removes the need for shrouds
• Increases resolution by minimizing chromatic irregularities
• Provides exceptional surface quality providing 40/20 scratch/dig
• Delivers exceptional out-of-band blocking

APPLICATIONS
BP Series are the most popular filters used in machine vision and factory automation systems and are a critical element in fluorescence imaging.

BN NARROW BANDWIDTH SERIES BANDPASS FILTERS

• Superior out-of-band blocking
• Designed for use with laser diodes lighting in applications with overwhelming light
• Reduces angular short-shifting effects

APPLICATIONS
BN Series filters are commonly used in factory automation applications where interfering ambient light and sunlight may be present, and in fluorescence applications to prevent cross-talk. NIR BN filters are commonly used in outdoor applications such as security surveillance and license plate recognition.

Bi NARROW INTERFERENCE SERIES BANDPASS FILTERS

• 20-35nm FWHM; Narrow bandwidth
• ≥85% Transmission
• Designed for use with laser diodes
• Blocks visible wavelengths through near-IR wavelengths while passing UV light
• Ideal wavelength separation when multiple light sources are present

APPLICATIONS
BI Series filters are used in various life science and laser analysis applications where only very narrow wavelengths need to be passed
