LED Drivers |
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 voltage.
Using the obtained voltage value it is possible to calculate the intrinsic LED temperature.
|
D-31M Driver
|
D-31M driver provides two operation modes:
- Quasi Continuous Wave mode (qCW). Using this mode it is possible to adjust current in range 25-250 мA and choose one of four frequency values (0.5, 2, 8 и 16 kHz).
- Pulse mode: In addition to frequency adjustment, pulse duration can be selected in range 0.6-20 µs. Peak current in pulse mode can be changed in the range 0-2 A.

DLT-27 LED Driver with temperature controller
|
Driver DLT-27M is oriented for operating with all Lms MIR LED models with built-in thermocoolers. Driver provides two operation modes:
- Quasi Continuous Wave mode. Using this mode it is possible to adjust current in range 25-250 mA. Modulation frequency is 16 kHz.
- Pulse mode. Peak current in pulse mode can be changed in range 0-2 A. Pulse duration is 1 µs.
Temperature controller built in DLT-27M provides selecting and stabilizing the LED chip temperature in a wide range.

PD Amplifiers |
Amplifier for Photodiodes AM-07M*
|
Amplifier AM-07 converts the output current of a signal source (such as Mid-Infrared photodiode) into voltage with amplification for subsequent use with various electronic systems, such as lock-in-amplifiers, oscilloscopes or A/D converters. Synchronous is built in the same package and gives direct current proportional to signal at selected frequency. Signal value is viewed on LCD Display.

|
Amplifier AMT-07M converts the output current of a signal source (such as Mid-Infrared photodiode) intoa voltage with amplification for subsequent use with various electronic systems, such as lock-in amplifiers, oscilloscopes or A/D converters. Synchronous detector is built in the same package and gives direct current proportional to signal at selected frequency. Signal value is viewed on LCD Display.
Amplifier AMT-07M is oriented for operation with photodiodes with built-in thermocooler and thermistor (LmsXXPD-TEM(-R) models). Customer can select and set PD operation temperature. Circuit with feedback will set the appropriate thermocooler current for maintaining the selected temperature.
