Short wave Infrared Bandpass Filter
|
The Midwest Optical BP1550 is a shortwave infrared bandpass filter with 1485-1645nm range
- Designed with a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths
- Test the effects of monochromatic illumination
- High transmission ≥90%*
- Superior out-of-band blocking
- StablEDGE® design reduces angular dependency and minimizes short-shifting effects
- Double-side polished glass for exceptional parallelism and optical flatness
- Available in sizes up to 165mm sq.
- Useful Range : 1485-1645nm
- FWHM : 190nm
- Tolerance : +/-10nm
- Peak Transmission : ≥88%
- Surface Quality : 40/20
- Compatible LED : 1550nm
