Linear array components – “spectrometer on a chip”

Linear arrays – taking lab analysis out into the field

Pyreos has unique capability to produce un-cooled pyroelectric linear array sensors which offer high performance right across the infrared spectrum and especially in the mid infrared. Our unique thin film pyroelectric material can be patterned to provide micron-scale individual sensor pixels on the thermally isolating membrane layer of our sensor device. These high-resolution patterned sensors are produced in high volumes using standard MEMS foundry processes.

New low cost solid state IR spectrometers and IR imaging devices are made feasible by using optics and the array to disperse different wavelengths of light onto each sensor pixel. Our customers are using this breakthrough product to provide new analytical solutions in medical, industrial, and scientific fields.  Pyreos also holds key patents on the optical designs.  We use this to advise our customers on design issues and to protect their designs in key markets.

The linear arrays are housed in a standard metal dual in line 16 pin package, that outputs an amplified, analogue multiplexed signal. The arrays can be supplied with a variety of filter window options including NIR and mid-IR linear variable filters (LVFs), as well as anti-reflection coated Si windows. These linear array products – spectral engines – provide a radical new low cost alternative approach to building IR spectrometers and spectral analysers.

Pyreos has a range of easy-to-use, PC compatible evaluation kits available immediately for rapid and full evaluation of our sensor technology. Our evaluation kits typically use standard and well known, off-the-shelf electronic components to take our sensor output signal and digitise it, so that it can be transferred and analysed via USB interface on a standard Windows-based PC.
