CB550 High Pass Orange Filter for Machine Vision

CB550 High Pass Orange Filter for Machine Vision The CB550 color glass is an orange-colored, absorptive long pass optical filter with a cut-on wavelength of approximately 550 nm. It is specifically engineered to block ultraviolet (UV), blue, and most green wavelengths while transmitting orange, red, and near-infrared (NIR) light. This spectral characteristic enhances contrast and provides more stable exposure in applications utilizing red/NIR illumination, such as machine vision inspection, barcode scanning, and CCTV systems operating under mixed lighting conditions. Compared to coated filter stacks, colored glass filters are inherently angle-insensitive and mechanically durable, ensuring consistent spectral performance even under wide angular fields of view or off-axis illumination. Therefore, coated filter designs should only be employed when necessary, with the operational angular range clearly specified. Standard dimensions include Ø12.5 mm, Ø25.4 mm, and 50×50 mm, with thicknesse…
