    • 2.83-2.90um MIR LED with Glass Cap

    Idealphptonics is pleased to announce new light-emitting diodes with a special glass cap, which increases the LED output optical power (up to 3-5 times). This allows for higher precision in various gas, liquid, and solid sensing and analysis applications. Along with other advantages (compact size, low power consumption, high modulation range), our LEDs become an even more impressive component basis for sensors and analyzers.

    Product features：Mid-infrared band; High optical efficiency; TO package; Fast response; Wide operating temperature

    Part Number：MP-LED-2830-0.3-TO18

    Application area：Moisture detection | Gas sensing | Medical diagnostics | Material analysis | Security monitoring

    To drive the LED, we recommend the following basic circuit connection:

      1.1.png      

    We recommend using quasi-CW mode with a duty cycle of 50% or 25% to obtain maximum average optical power, and short pulse mode to obtain the highest peak power. Strong CW (continuous wave) mode is not recommended.

    Precautions

    Please check your connection circuit before turning on the LED.

    Please pay attention to LED polarity: the anode is marked with a red dot; reverse voltage is prohibited.

    Do not connect the LED to a multimeter.

    Please control the current applied to the LED and do not exceed the maximum allowable value.

    Do not touch the glass cap or apply any force to it.

    Please pay attention to the operating and storage temperatures; exceeding the allowable range may cause irreparable damage to the glass cap.
