New optoelectronic devices for the Near and Mid-Infrared spectral range open completely new possibilities for portable sensors creation. Using infrared LED-PD optopairs allows developing an instrument that is smaller, less expensive and energy-saving.
Standard multi-wavelength matricesPossibility of driving LED dies independently allows scanning a broad spectral range. Standard LMSNT 6-element multi wavelength LED array comprised of LED dies with peak wavelengths 1.3, 1.4, 1.6, 1.7, 1.9 and 2.1 μm covers the range from 1.3 μm to 2.1 μm.
The 6-element multi wavelength LED array is available in the following packages:
• TO-5 with a cap (with a glass window) - Lms13-14-16-17-19-21LED-6M;
• TO-8 with a thermoelectric module with a cap (with a glass window) - Lms13-14-16-17-19-21LED-6M-TEM.
*1 Repetition rate: 0.5 kHz, pulse duration: 20 µs, duty cycle: 1%.
Especially for operation with matrices with independent driving possibility there was desinged multichannel LED driver MCD.
Standard matrix types are basic versions that were designed mainly to give an idea about the possible array arrangement and evaluate its performance. We are always open to cooperate and to design a special solution for the exact customers’ needs. More about custom multielement solutions:
Principle of indipendent LED dies driving for obtaining a broad scanning spectrum is used in our new devices - LED analyser (LA-T) and LED minispectrometer (under development) which contain 8-element multi-wavelength LED array and a wide-band photodiode. More information:
