Infrared (IR) Bandpass Filter Description
The OP5312 is an 850nm infrared bandpass filter with 40nm FWHM bandwidth. It delivers >85% peak transmission and deep out-of-band blocking (OD≥3.0 from 300nm to 1100nm). The hard-coated dielectric construction ensures durability in harsh environments, making it suitable for FLIR, security cameras, environmental monitoring, and laser line separation applications.
