Longpass Filter, Colored-Glass Alternative, 6.5 in., 360 nm Cut-on
The 65CGA-360 Colored-Glass Alternative Filter is a 6.5 inch (165.1 mm) square long-pass filter with a 360 ± 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. Specifications
