Optical coating

Black film

Black Coating /Highly neutral-density Filter, which can significantly inhibit the penetration and reflection of light, and can be used for ultraviolet/visible light to infrared light

Band-Pass Filter

Only the light in the target band can pass through, and the signal-to-noise ratio can be greatly improved by 100~100,000 times.

Anti-reflection film

Anti-reflective film reduces surface reflection and greatly increases the penetration rate, and is mostly used to enhance signal strength and reduce noise caused by stray light and crosstalk, such as glare and flare.
