D25x2mm ZJB380 UV‑Visible IR Longpass Filter

D25x2mm ZJB380 UV‑Visible IR Longpass Filter   The Color glass ZJB380 (50×50 mm) longpass optical filter effectively blocks ultraviolet (UV) radiation below approximately 380 nm while transmitting visible and near-infrared (NIR) wavelengths, making it an ideal front window solution for outdoor cameras or inspection systems. With a cut-on wavelength of around 380 nm, the filter efficiently attenuates UV light below this threshold, thereby minimizing UV-induced haze and color distortion to ensure clear and color-accurate imaging performance. This optical characteristic makes the filter well-suited for use as a front window in true day/night camera systems. During daytime operation, it functions as a UV barrier while supporting the integration of a UV and IR cut filter in the color imaging path. At night, the filter allows the transmission of 850 nm or 940 nm wavelengths, facilitating high-quality infrared imaging without compromising system functionality.   Comparitive Type List Of Color…
