LUXACRYL®-IR - Infrared transmitting PMMA film
LUXACRYL®-IR is black acrylic sheet absorbing daylight, but allowing maximum transmittance of near-infrared light
It has all the properties required by windows and filters in IR-applications such as light barriers, IR sensors, IR lamps, IR cameras, and control units (remote controls).
LUXACRYL-IR is often referred to as infrared filter film because it performs the same function – the targeted transmission of infrared light while shielding visible radiation. Unlike flexible films, however, LUXACRYL-IR is a cast, dimensionally stable acrylic that is particularly suitable for precise optical applications.
The material variant of LUXACRYL®-IR is „black 1698“. If transmission (permeability) below 800 nm is required, other color variants are available.
LUXACRYL®-IR is ttv’s precision cast acrylic (PMMA) for applications with requirements of excellent optical quality, in black tint with maximum transmittance for near infrared light.
Base: Cast precision acrylic glass based on polymethyl methacrylate.
Areas of application for infrared filter films made of acrylic
All infrared applications such as light barriers, light grids, sensors, and control units.
Also suitable as an alternative to infrared filter films in areas where higher dimensional stability and optical precision are required.
Sheet size
Standard: approx. 850 x 850 mm; thicknesses from 0.5 through 6.0 mm, thickness tolerance ±0.1 mm (up to thickness 3.0 mm). ttv also supplies cut to size or machined to customer’s drawings (including silk screen printing and adhesive).
Frequently asked questions:
Why is LUXACRYL-IR also referred to as infrared transmitting film or filter?
The term “infrared transmitting film” describes the function performed, not the form of the material used. LUXACRYL-IR acts like an infrared transmitting film by blocking visible light and allowing IR radiation to pass through. Unlike a real film, however, it is a solid acrylic sheet – more robust, durable, and with precisely controlled transmission
What are the advantages of LUXACRYL-IR over classic infrared filter film?
- Dimensional stability: No warping or wrinkling as with films.
- Optical precision: Uniform and even transmission across the entire surface.
- Mechanical strength: Ideal for device covers and housing parts.
- Temperature resistance: Can be used continuously up to approx. 80 °C.
- Custom processing: Available cut to size, printed, or with adhesive coating.
Is LUXACRYL-IR resistant to aging and weathering?
The material has very good long-term stability. It is UV-resistant, does not yellow, and remains visually and mechanically stable even after prolonged use. The appropriate variant can be selected for outdoor use or applications with high radiation intensity.
How does LUXACRYL-IR differ from other IR materials?
Compared to glass or polycarbonate filters, LUXACRYL-IR offers better workability and lower weight while maintaining high optical quality. Compared to flexible IR films, it scores points with its constant transmission, dimensional stability, and high surface quality.
