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 wavelengths while blocking near-infrared light. They’re a strong fit for NVIS-compatible displays and avionics applications where reducing NIR emission helps protect night-vision performance and improve system compliance.
In addition to controlling NIR transmission, these filters can also reflect or reduce NIR-related heat, making them useful for hot mirror applications in heat-sensitive optical systems. With excellent optical clarity and durable substrate options, CLAREX NIR-cut filters deliver consistent performance for demanding display, instrumentation, and optical integration environments.
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.
