Laser Fluorescence SP850 Shortpass Filter
- ModelSP850
- SpecificationCustomizable
- MaterialOptical glass
Description
The SP850 is a high-performance shortpass filter that cleanly separates visible/near-IR light below 850 nm from long waves above 900 nm. The transition at 850 nm is steep, the passband keeps average transmission above 92%, and the blocking zone reaches T<0.1% across 900–1100 nm — meeting demanding needs from spectral analysis and LiDAR to biomedical imaging.
Specifications
- Working band: 420nm-1100nm
- Max. transmission: T>92%
- CWL: 850nm
- Blocking band: 900nm-1100nm
- Blocking depth: T<0.1% (customizable)
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
