#d8782a SP870 Near-IR Dichroic Multispectral Shortpass Filter
SP870 Filters are useful for passing multiple wavelengths with a broad spectrum camera. These filters can also be used in some hyperspectral/multispectral imaging applications. The second surface is provided with a high efficiency anti-reflection coating.
- Useful Range : 415-870nm
- Cut-off Wavelength 50% T : 870nm
- Tolerance : ±10nm
- Peak Transmission : ≥90%
- Surface Quality : 60/40
