Chroma Technology H-Alpha3 LRGB Filter Set

This Chroma Technology H-Alpha3 LRGB filter set includes H-alpha 3nm, luminance, red, green, and blue filters. Chroma Technology filters have extremely durable, sputtered hard coatings using single substrates of the best glass, eliminating the need for laminations. These coatings can withstand humidity changes and extreme temperature fluxes and remain spectrally accurate in center wavelength (CWL) and bandpass adherence. All primary filter coatings are applied on the front surface and anti-reflection coatings on the rear surface to prevent ghosting and to maximize transmission.
