Red/Infra pass Filters
Red / Infrared Pass Filters (Red / IR Pass)
Also known as Cold Mirrors or Longpass Filters.
Functions:
Designed to block (absorb or reflect) visible light while transmitting infrared light, or to reflect short-wavelength visible light while allowing red and near-infrared laser light to pass with high transmission.
Applications:
Night vision security cameras and surveillance systems
Barcode scanners and reader optics
Laser spirit levels and line laser instruments
Laser distance meters and rangefinders
Infrared sensing and receiving optical systems

Information and Notes
1. IR Pass filters / Cold Mirrors provide bandpass or longpass performance for optical sensors, red laser systems, and night vision devices.
2. Custom optical coating services are available upon request based on required wavelength ranges, bandwidths, and transmittance specifications.
3. IR Pass filters / Cold Mirrors feature multilayer dielectric films deposited via vacuum evaporation, typically consisting of 36 to 58 coating layers according to custom designs.
4. Coating process: PVD-EBGE (Physical Vapor Deposition - Electron Beam Gun Evaporation).
5. O580H is an absorptive colored glass filter. It is manufactured from formulated glass blocks processed through slicing, grinding, and polishing, achieving optical blocking via internal material absorption.
6. O570P is an optical acrylic (PMMA) material suitable for injection molding. While initial tooling/mold costs are higher, it offers lower unit costs ideal for high-volume mass production.
7. The spectral transmittance curves shown are measured at a 0° angle of incidence (AOI = 0°).
8. Spectral curves represent actual sample measurements and may vary slightly from manufacturing lot to lot, while remaining within defined optical specifications.
9. Website specifications are for reference only; final shipments are subject to the specifications confirmed by both parties.
