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 CH4.
Every system is an out-of-the-box solution and can be launched with minimal effort.
Standard packaging arrangement:
СDK-c is an advanced evaluation kit for CO2 detection with glass-covered LED and photodiode, which includes all the needed components for quick and simple start. The possibility to change the parts within the kit easily makes the kit a flexible and utility solution.
MDK-c is an advanced evaluation kit for CH4 detection with glass-covered LED and photodiode, which includes all the needed components for quick and simple start. The possibility to change the parts within the kit easily makes the kit a flexible and utility solution.
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 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 voltage. Using the obtained voltage value it is possible to calculate the intrinsic LED temperature.
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.
