What is the difference between infrared transparent acrylic and filters?

First of all, let's talk about the manufacturing structure of the infrared filter: the infrared filter is made of infrared transparent acrylic plastic particles, which are extruded into an infrared filter plate through an extrusion process, and then cut into each small piece size and shape by laser. What is an infrared filter? Simply put, an infrared filter is an optical-grade material that blocks visible light and only transmits infrared light.

This infrared filter has strong plasticity and can be processed into any shape and size, which greatly expands the scope of use. In addition, the acrylic infrared filter has the characteristics of durability, strong penetration rate, light weight and high cost performance, which makes the whole product beautiful and practical. And widely used in infrared gas analyzers, night vision products, infrared detectors, infrared receivers, infrared sensors, infrared communication products. Specific to products such as: surveillance cameras, remote controls, infrared curtain wall products, infrared sensor toilets, faucets, hand sanitizer devices, infrared thermometers, infrared printers, interactive electronic whiteboards, infrared touch screens, fingerprint recognition machines, face recognition systems Wait.

Optical Glass Filters:

(1) Made of colored glass, usually black, such as IPG-800. It absorbs visible light and allows infrared light to pass through. If you look at the sun through this infrared filter, you can still see a red sun. Suitable for infrared imaging.

(2) An infrared filter is made by vacuum coating on the optical white glass, such as IPGC-720, this type is also called an optical cold mirror, which will reflect the visible outside and allow visible light to pass through. The exterior looks silver, like a mirror. If it is a mid-to-far infrared filter, it should be coated on Si, Sapphire, and quartz glass.
