II. Line Arrays


Overview

Pyreos has a unique capability to manufacture un-cooled pyroelectric line array sensors that offer high performance right across the infrared spectrum. Our unique thin film pyroelectric material can be easily patterned to provide individual sensor pixels on the thermally isolating membrane layer of our sensor device. By dispersing different wavelengths of light onto each sensor pixel, new, low cost, solid state IR spectrometers and IR imaging devices become possible. Our customers are using this breakthrough product to provide new analytical solutions in medical, industrial, and scientific fields.

The line 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 (LVF), as well more standard options such as anti-reflection coated Si, ZnSe, or Ge windows. These line array products provide a radical new low cost alternative approach to building IR spectrometers and spectral analysers.

IV. IR Emitters


Overview

Pyreos is pleased to offer a range of blackbody IR emitters. Like our infrared sensors, these MEMs based emitters offer fast frequency of operation, high reliability, excellent value and new possibilities in product design. The blackbody output means that NDIR gas sensing is no longer limited by the sodium glass sleeve of IR bulbs.

The emitters have an almost instantaneous thermal on/off response to an electrical signal, similar to that of an LED. This makes it possible to drive the emitter efficiently, reducing power consumption, whilst still achieving good modulation depth and device lifetime, even when generating operating temperatures of 500-700°C.

Pyreos offers emitters as die, single devices in TO and surface mount packages, and also as linear emitter arrays to complement our IR sensor ranges. Packaged emitters are available with a choice of reflectors and window options to provide a solution for the highest brightness requirement to the physically smallest, low power option

Features & PERFORMANCE
  • Fast frequency with good modulation
  • Sharp ON/OFF
  • High temperature
  • Long lifetime
  • Blackbody emission
Key Benefits
  • Performance
  • Increased wavelength range
Ideal For
  • Optimised performance when used with Pyreos IR sensors

V. Sensor & Emitter Die


Pyreos thin-film MEMs based IR sensors and emitters provide a route to tuning IR device performance to suit an application. This can be anything from overall S/R ratio & sensitivity, peak wavelength sensitivity and frequency response to optimisation for a certain size of device. It includes ways to tune capacitance, pyroelectric coefficient, and other parameters. All of the key device parameters can be controlled by the careful optimisation of the thin-film device structure, which is controlled with nm level precision during manufacture. Whatever you require, we have the tools to design and model it for you before prototyping your new sensor die via our low cost, multi-party wafer service. Just contact us to discuss your requirements and we will be happy to lead you through our prototyping service.

We also have many standard designs which we can supply for initial proof of concept, with small quantities of tested good die provided in gel packs.
