Longpass Filter, Colored-Glass Alternative, 25.4 mm, 550 nm Cut-on

The 10CGA-550 Colored-Glass Alternative Filter is a 1 inch (25.4 mm) diameter long-pass filter with a 550 ± 5 nm cut-on wavelength. Colored-Glass Alternative filters have a steep transition between the region of transmission and rejection (blocking) that is much steeper than colored glass filters. Colored-Glass Alternative filters have out-of-band rejection ≥OD 5 to 200 nm. Typical transmission is ≥90% average.
