Pyroelectric Linear Arrays

The LTx family of pyroelectric linear arrays is specifically designed for non-contact temperature measurement and infrared spectrometry. The arrays include a lithium tantalate chip with 128, 256 or 510 elements. The signals produced by the elements are processed in a CMOS circuit. Signal processing is carried out by the analogue circuitry, including an adapted low-noise preamplifier for each pixel, a multiplexer, an output amplifier. The pyroelectric chip and CMOS readout circuit are located on a thick film substrate, which is mounted inside a hermetic metal housing. The incident radiation passes through a window or filter, is transparent to infrared wavelengths, and reaches the sensitive elements.

The preamplifiers transform the signal charges of each pixel into a signal voltage, include bandwidth limiting and pass the amplified signal to the sample & hold for the read-out process. The digital inputs are CMOS compatible. For measurement of the detector temperature a sensor (type AD 590) is integrated into the package. It provides an output current which is proportional to the temperature.

In common with all pyroelectic detectors, the incoming infrared radiation needs to be modulated for a measurement to be made. Ion-beam milled pyroelectric detector chips with a thickness of approximately 5 μm enable a high responsivity and a low noise equivalent power NEP. An additional metal black coating („M“ in type designation) realizes a high and homogeneous spectral absorption. Detector chips with ion-beam etched thermal isolation trenches („SL“ in type designation) allow low modulation frequencies up to 10 Hz with excellent signal/noise-ratio.

Evaluation Kit

The Evaluation Kit allows easy operation of the PYROSENS arrays. It consists of a small circuit board with complete electronics and software by which the electronics is controlled via USB connection from a Windows PC. The power can be provided by the USB port or a separate power supply (9 V). For synchronisation with further external components, such as for radiation modulation, a trigger pulse is provided. The read-out cycle can be adjusted between 1 and 30 lines/s.

A DLL interface for the integration of the evaluation kit in custom software solutions and common laboratory software is available. Thus, commissioning and integration of PYROSENS arrays in their own software and system solutions become even easier. The interface permits access to all array parameters via API functions and reading out the pixel values.

The evaluation kit can be integrated into a variety of software environments, e.g.

– NATIONAL INSTRUMENTS LabVIEW

– MathWorks MATLAB

– Microsoft Visual Studio

– Embarcadero RAD Studio

For the development of software in C / C ++ corresponding header and lib files are included.

Linear Variable Filter

Introduction

Infrared Linear Variable Filters are narrow band filters where the Centre Wavelength (CWL) changes with distance along it’s length, this is shown in the diagram below for a 2.5-5.0 µm type. Our range of stock LVF s allow the user an opportunity to explore the technology but at a relatively low cost.

1. Our stock LVF s cover 3 ranges 0.9-1.7 µm, 1.3-2.5µm and 2.5-5.0µm , these can be purchased from our web-shop.

2. We also manufacture custom LVF’s, contact us to discuss further.

3. Applications include mini-spectrometers, multi-gas analysis,industrial process monitoring and many more.

Features of Generation 2 Infrared Linear Variable Filters

- 2 ranges covered, 0.9-1.7µm and 1.3-2.5 µm.

- Width/FWHM =1% x Centre Wavelength.

- Blocking greater than OD 3.5 average outside passband.

- Specifically for systems where higher signal to noise ratio is critical.
