IDAS UHB-RS 52mm Filter

View our closest star, The Sun, sun spots, and granulation with an IDAS solar filter.

IDAS UHB-RS (UV/heat blocking, reflection suppression) solar filters are the first innovation in many years in the area of broadband solar filters. These are specifically designed to address the problem of internal reflections and scattering which occur inside even high-quality camera lenses and telescopes. Rather than providing a mirrored internal surface, these filters are treated for suppression of reflections within the filter (1/10,000 reduction) as well as internally reflected light coming back towards the filter from the imaging sensor and lens elements.

IDAS solar filters are high-quality (manufactured in Japan) glass filters designed for safe* (high UV and IR rejection) visual and photographic use.

Price does not include shipping and brokerage, which will be confirmed before actual payment is taken.
