Chroma Bessel UBVRI Photometric Filters

Chroma Bessel filters are photometric filters matched to the standard Johnson-Cousins UBVRI system, used to measure star brightness and color in calibrated bands. The line includes individual U, B, V, R and I Bessel filters and a complete UBVRI filter set.

They suit observers doing variable star work, exoplanet transit timing, asteroid light curves or student research, where results must be comparable with professional catalogs. Chroma's hard-coated interference filters give stable passbands over time, an important point for long photometric programs.
