LED Micro Sensor NT

LED Microsensor NT possesses the full cycle of technological processes needed for creation of LEDs and PDs from the very beginning to complete products.

Middle-Infrared LEDs
Our mid-infrared (1600-5000 nm range) Light emitting diodes (LEDs) possess certain competitive advantages

Infrared Photodiode Detectors
Detectors we produce are the semiconductor photodiodes (PDs). PD heterostructure is formed by sequential epitaxy of semiconductor layers on the surface of a crystal substrate. Light is absorbed in the active layer of PD and the spectral response of the PD is determined by the energy gap of the material in the active layer.

Electronics for LEDs and PDs
According to the Customers’ requests we developed different models of electronic units oriented for optimal operation with Mid Infrared LEDs and Photodiodes. Drivers and Amplifiers allow arranging a very flexible and easy-to-use set-up to carry out first experiments concerning optical measurements of gases, liquids and solid materials absorption in the middle infrared spectral range. The available operation regimes can be selected to take maximum benefits of using new narrow band-gap Mid IR LEDs and PDs.

Evaluation Kits
Mid-infrared light-emitting diodes and photodiodes manufactured by LED Microsensor NT, LLC 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.

Application
In 1600-5000 nm spectral range there are characteristic absorption bands of such important chemical agents as water H2O, methane CH4, carbon dioxide CO2, carbon monoxide CO, acetone CH3COCH3, ammonium NH3, C2H2, C2H4, C2H6, CH3Cl, OCS, C2HCl3, HCl, HOCl, HBr, H2S, HCN, CHBr3, H2CO, С2H4Cl2, HF, HNO3, NO2, SO2, glucose and many other organic and non-organic substances. Thus, there is a huge range of applications for optical analysis.
