Microtech BG - Evaluation kits

Evaluation Kits

Mid-infrared light-emitting diodes and photodiodes manufactured by Microtech BG, have already found their usefulness in a vast area of applications. For the first-time users we announce sample systems and kits that enable fast preliminary experiments with mid-infrared LED-PD optopairs for different detection purposes.

The new line of devices includes evaluation systems for CO₂ and CH₄ for precise experiments with gases, evaluation kits that offer high flexibility and miniature on-board sensor modules for CO₂ and CH_4.

Every system is an out-of-the-box solution and can be launched with minimal effort.

Standard packaging arrangement:

a light-emitting diode with a driver;
a photodiode with a preamplifier;
a synchronous detector;
an optical chamber.

LED Drivers

MCD Multichannel LED Driver

MCD driver is a utility board that unites several functions: - power supply of arrays comprising of Mid-IR LEDs, supporting up to 8 channels;
- photodiode signal processing and amplification;
- synchronisation of LED and photodiode signals.

D-41i LED Driver

D-41i Driver provides pulse mode of operation. Using this mode it is possible to choose one of five current values (0.2/0.6/1/1.5/1.9 A) and select one of four frequencies (0.5/1/2/4 kHz). It is also possible to choose pulse duration within five values (5/10/20/50/150 µs).

D-51i LED Driver

D-51i Driver has the same characteristics as D-41i and also has an important feature: - Temperature control – possibility to define LED p-n junction temperature using current-voltage dependence. Driver generates the low current signal for plugged LED, measures and puts out the

mD-1c Minidriver

mD-1c Minidriver provides qCW mode of operation with fixed signal data parameters (amplitude, repetition rate and pulse duration).

mD-1p Minidriver

mD-1p Minidriver provides pulse mode of operation with fixed signal data parameters (amplitude, repetition rate and pulse duration).

PAb Photodiode preamplifier board

PAb photodiode preamplifier board

PAb preamplifier is oriented for amplification and conversion of the pulse current signal generated by LMSNT photodiodes (PDs). Preamplifier enables PD operation at photovoltaic mode (with no reverse bias) – mode in which photodiode becomes the source of photocurrent. PD photocurrent is amplified and converted by preamplifier into voltage signal.

SDM Synchronous Detector

SDM synchronous detector

SDM synchronous detector measures the voltage signal from the output of photodiode preamplifier and converts it to the DC voltage signal proportional to amplitude of voltage from input.
