Plastic that''s transparent to IR range sensors

Some transparent plastics such as acrylic glass are used where there is need to transmit IRlight or visible light. Poly(methyl methacrylate) (PMMA) passes infrared light of up to 2,800 nm and blocks IR of longer wavelengths up to 25,000 nm. Colored PMMA varieties allow specific IR wavelengths to pass while blocking visible light (for remote control or heat sensor applications, for example). A ...

Noncontact IR temperature measurement of plastic film

Noncontact temperature measurement of thin plastic films is in practice a difficult measurement task. Depending on the type of plastic, the measurement must be performed in different spectral ranges. In research and development of printable films, the surface temperature of heated plastic films is detected using a CTP7 pyrometer (spectral range µm). Furthermore, the thermoMETER CTP3 ...

Infrared transparent compounds Wittenburg Group

Most transparent plastics are infrared transmitting. These grades are opaque to visible light and allow infrared light through. Unlike glass, you can put all our IR grades in front of DVR’s, cable boxes, DVD players etc. and your remote control, wireless router etc. will still work. Our PCIR Black material only transmits infrared, which makes it ideal for hiding a CCD video camera. Our ...

The Correct Material for Infrared (IR) Applications

Infrared (IR) radiation is characterized by wavelengths ranging from 1000μm (750 1000000nm). Due to limitations on detector range, IR radiation is often divided into three smaller regions: 3μm, 3 30μm, and 30 1000μm – defined as nearinfrared (NIR), midwave infrared (MWIR), and farinfrared (FIR), respectively (Figure 1). Infrared products are used extensively in a ...
