Chroma Technology Clear Filter, 2" Mounted
Chroma Technology Clear Filter, 2" Mounted
This clear filter from Chroma Technology is a protective filter that does not provide any ultraviolet or infrared blocking. It is in a 2" diameter mounted form factor.
Chroma manufactures astronomy filters with durable, sputtered hard coatings using single substrates of the highest quality glass, eliminating the need for laminations. Primary filter coatings are applied on the front surface and anti-reflection coatings on the rear to prevent ghosting and to maximize transmission.
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 Chroma filters may be used with focal ratios of f/4 or smaller. Chroma astronomy filters are coated on 3.0 mm thick substrates and are parfocal with all other Chroma astronomy filters, except the LoGlow Light Pollution Filters.
Manufactured in Vermont.
