CHROMA, Optical Filters for Astronomy Applications.

Lunático introduces the Chroma filters, designed and manufactured by the prestigious American company Chroma Technology Corp., manufacturer of precision optical filters and coatings with 30 years of experience.

The Chroma filters are the highest quality astronomy filters with durable, sputtered hard coatings using single substrates of the best glass, eliminating the need for laminations. 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.

Highly precise and accurate, the passbands of these filters remain spectrally stable and do not drift in response to extreme temperature fluctuations or changes in humidity. All filters may be used with apertures of f/4 or smaller.
