NMOT specializes in the production of trans-infrared acrylic filter (PMMA), also known as infrared window or acrylic transparent plate. The infrared acrylic filter is made of black or dark red acrylic material. It's characterized by giving a black vision in the visible light range (transmission at 400-700 nm is less than 1%), but it can pass through the near infrared region of 720-1100 nm wavelength. The infrared transmittance varies from 80% to 95% depending on the thickness, working band and color requirements of the components.

Applications
It's not only helping to pass the infrared signal, but also its visual black can easily cover the internal structure. So, it's widely used in infrared transmission communication components, like infrared signal transmission or infrared window for mobile phones, computers, home appliances, automobiles, infrared touch screens, etc. Products can be poduced according to customer's specifications.
