Фильтр длинного пропускания, диэлектрик, 25,4 мм, 900 ± 7 нм, отсечка, 920–1200 нм Модель: 10LWF-900-B

The 10LWF-900-B Dielectric Longpass Edge Filter is a 1 inch (25.4 mm) diameter optical filter with a 900 &plusmn,7 nm cut-on wavelength and a 920 to 1200 nm transmittance range. Long-wave pass filters have a steep transition between the region of transmission and reflection that is much steeper than colored glass filters. Longpass filters have out-of-band rejection &ge,OD 3 to X-ray. Typical transmission is &ge,80%.
