Description
JYOPTO supplies IR cut-off filters for bio-detection and fingerprint-recognition equipment in sizes such as Ø23.0×0.7 mm, Ø15.0×0.7 mm, Ø9.0×0.55 mm, Ø8.2×0.7 mm, 12×12×0.7 mm and 6.8×6.8×0.7 mm. Average transmission across 420–620 nm is above 90%, near-IR blocking is deep, surface quality options include 20-10/40-20/60-40/80-50, and the back side carries a broadband BBAR coating. Applications: bio-detection instruments, fingerprint imaging, industrial cameras, phone telescopes, digital cameras, digital microscopes, security cameras (CMOS & CCD), camcorders and building-monitor lens systems.
