What is an IR Passing Acrylic Filter?
IR Passing Acrylic Filters, also known as Infrared Windows or Plastic Optical Filters, use PMMA as the substrate material. Featuring a black or deep red appearance, they perfectly block visible light while allowing specific near-infrared wavelengths to pass through with high transmittance.
What is typical application for IR Passing Acrylic Filters?
When selecting Infrared Transmission Acrylic Filter, the wavelength will be one of key parameter to be designated, the filter’s transmission peak must align with your infrared source. Secondly, visible light blocking, it determines how well the filter hides internal components. Third, infrared transmittance, this directly impacts the signal strength and sensitivity of your device. Forth, dimensions, including shape and thickness. Fifth, environmental durability, etc.
Shenzhen Hengda Liyuan Optoelectronics introduced advanced optical technology that apply depositing nanomaterials through ion-assisted evaporation onto a multilayer hard film in a high vacuum environment which coating layer is firm and has good tightness, and small bandwidth drift. Liyuan optoelectronics have been focus on optical coating for more than 17 years and offer one-stop optical filters solution including Narrow Bandpass Filters, IR cut-off Filters, Longpass & Short Filters, Notch Filters, ND filters, Star filters and Optical sapphire block.
