Longpass Filter, Colored-Glass Alternative, 25.4 mm, 1000 nm Cut-on

Colored Glass Alternative Longpass Filters

The 10CGA-1000 Colored-Glass Alternative Filter is a 1 inch (25.4 mm) diameter long-pass filter with a 1000 ± 9.0 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.
