Bandpass Filters
Bandpass Filters
Also known as Narrow Bandpass Filters (NBPF) or Wide Bandpass Filters (WBPF).
Functions:
Designed to selectively transmit a specific wavelength range while effectively blocking out-of-band wavelengths. Features high in-band transmission, deep blocking (high optical density), and steep spectral edge roll-off.
Applications:
Medical diagnostic equipment and analytical instruments
Automated optical inspection (AOI) systems
Fluorescence microscopy and imaging
Spectroscopy and optical sensing systems

Information and Notes
1. Bandpass filters feature 34 to 62 thin-film dielectric layers vacuum-deposited on the substrate.
2. Coating process: PVD-EBGE (Physical Vapor Deposition - Electron Beam Gun Evaporation).
3. Select bandpass filters are constructed as multi-substrate filter assemblies, with overall thickness ranging from 1.1 mm to 4.4 mm.
4. Bandpass filters are also available pre-mounted in standard camera thread rings (e.g., M49, M52, M55, M58).
5. The spectral transmittance curves shown are measured at a 0° angle of incidence (AOI = 0°).
6. Spectral curves represent actual sample measurements and may vary slightly from manufacturing lot to lot, while remaining within defined optical specifications.
