The BP 850-80 HT from Schneider-Kreuznach is a Magnetron Sputtered Bandpass Filter that transmits wavelengths from 430 to 500 nm. It has an average transmittance of over 95% in the passband and performs deep blocking of 390 nm UV light & 530-1000 nm wavelengths with a transmittance of less than 1%. This ULR coated filter has a thickness of 1-2 mm and 1’ parallelism with a wavefront distortion of 0.2-0.35. It is available in a flat surface package that makes it ideal for high end inspection systems in automation, 3D Measurement, food & beverage inspection, ophthalmology, microscopy and robotics applications.
