Near-Ultraviolet (UV) Interference Bandpass Filter, 344-358nm - MidOpt Bi350 Size:30.5mm 905nm Bandpass Filters are often

905nm Bandpass Filters are often necessary for reducing unwanted noise from sunlight and other ambient light sources

it's also recommended for protecting the camera’s sensor from stray light emitted by lasers or other high power near-IR (NIR) light sources

The PR120 is anti-reflection (AR) coated to limit glare and minimize reflection loss and is oleophobic coated to prevent finger print smudging and to keep oil and other solvents from collecting on the lens in a wide range of machine vision applications where environmental conditions can cause imaging problems

It's often used together with a neutral density (ND) filter

Near-Ultraviolet (UV) Interference Bandpass Filter, 344-358nm - MidOpt Bi350 Size:30.5mm 905nm Bandpass Filters are oftenThe MidOpt Bi350 Near Ultraviolet (UV) Interference Bandpass Filter can be used with 350nm UV LED, UV fluorescent and other UV producing lamp based lighting. The Bi350 is used in consumer, medical and scientific applications including insect attraction, pharmaceutical and other instrumentation. Bi350 filters are designed to block visible (VIS) through near infrared (IR) wavelengths while passing UV light. They are also useful for near UV fluorescence
