785nm, 20mW Laser Diode Module

785nm, 20mW Laser Diode Module Overview:

The MD L-E-785 diode laser module is a precision instrument designed for high resolution spectrum analysis and precision measurement. It features a narrow spectral line width, stable wavelength, and long lifetime, making it ideal for a wide range of applications. The module operates in CW mode with an output power ranging from 1 to 20mW, and has a power stability of less than 1%, 3%, or 5% over a four hour period depending on the model.

The module has a warm-up time of less than 15 minutes and operates at an operating temperature range of 20-30°C. It comes with a PSU-III-FDA power supply that accepts input voltages ranging from 85-264VAC, and has an expected lifetime of up to 10,000 hours with a one year warranty period.
