Near-Infrared Cut Filters
(NIR-Cut)
Transmits visible wavelengths and cuts near-infrared (NIR).
CLAREX Near-Infrared Cut (NIR-Cut) filters are high-performance acrylic and polycarbonate sheets engineered to transmit visible light while reducing or blocking near-infrared (NIR) wavelengths. They are well suited for displays, imaging systems, instrumentation, backlights, and other optical applications where visible and NIR transmission must be carefully controlled.
Available with durable acrylic and polycarbonate substrate options, CLAREX NIR-cut filters can be tailored to meet the optical and performance requirements of demanding applications.
Benefits of CLAREX Near-Infrared Cut Filters
Visible Light Transmission
Transmits visible wavelengths while cutting near-infrared (NIR) light.
Proven Standard Coating
Standard HPP600 coating design delivers reliable, repeatable performance.
Flexible Substrate Options
Available in hard-coated polycarbonate or cast acrylic to match durability and processing needs.
Enhanced IR Blocking
IR-cut coatings applied to both front and back surfaces for more consistent NIR reduction.
Distinct Optical Appearance
Standard HPP600 NIR-cut coating produces a blue/green tint in transmitted light and a reddish tint in reflections (see video).
High Clarity & Durability
High optical clarity and rugged performance suited for professional and industrial NIR cut filter applications.
Common NIR-Cut Applications
Designed for applications requiring controlled near-infrared attenuation while maintaining visible light transmission.
NVIS-Compatible Displays & HMIs
Filters for displays and interfaces that require controlled NIR output for night vision compatibility.
Avionics Displays, Cockpit Instrumentation & Control Panels
Optical filters for cockpit displays, controls, and indicators requiring precise visible and NIR transmission.
Backlit Displays & Lighting Systems
Filters that reduce near-infrared transmission while maintaining visible light output.
Hot Mirror & Heat-Rejection Optics
NIR-filtering components that help reduce near-infrared energy in sensitive optical assemblies.
Medical, Laboratory & Scientific Instruments
Filters for imaging and analytical instruments requiring visible and near-infrared separation.
Photography & Video Cameras
IR-cut filters that help prevent near-infrared wavelengths from affecting visible-light image capture.
Sample materials may be available to help you evaluate material performance.
