Description

The SP875 shortpass filter transmits light below 875 nm and blocks the near-infrared band above. With steep transition and deep blocking it is well suited to imaging, machine vision and NIR rejection in sensing systems.

Specifications

• Transmission band: 725–875 nm
• Min. transmission: T>90%
• CWL: 900 nm (T = 50%)
• Blocking band: 925nm-1100nm
• Blocking depth: T<0.1%

Applications

• IR-Cut filters for CMOS/CCD cameras, CCTV, dashcams and phone cameras
• Fluorescence microscopy (excitation/emission separation)
• Raman spectroscopy (Rayleigh scattering suppression)
• Machine vision and color imaging systems
• Fingerprint and biometric imaging devices
• Medical and beauty optical equipment
• Astronomical observation and spectroscopy
