Фильтр длинного прохода, альтернатива цветному стеклу, 2x2 дюйма, 630 нм Модель с отсечкой: 20CGA-630

The 20CGA-630 Colored-Glass Alternative Filter is a 2 inch (50.8 mm) square long-pass filter with a 630 &plusmn, 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.
