The 20CGA-695 Colored-Glass Alternative Filter is a 2 inch (50.8 mm) square long-pass filter with a 695 ±, 6.0 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 &ge,OD 5 to 200 nm. Typical transmission is &ge,90% average.
