The NF550 Magenta Dichroic Filters are technically not Shortpass Filters but are more commonly referred to as “Notch Filters”. They block a certain wavelength range while passing all others; only green wavelengths are blocked while all other light passes. The result is that objects take on a reddish-purple appearance when viewed in color.
- Useful Range: 395 to 475 nm, 605 to 700 nm
- Cut-off Wavelengths 50% T: 480/590 nm (cut-off/cut-on)
- Tolerance: +/- 10 nm
- Minimum Peak Transmission: 90%
- Surface Quality: 40/20
