Product Overview

The 201-3-650 is a self-contained Laser Diode Module with fixed focus and low power usage. It is ideal laser for general purpose use. It is an ideal replacement for a helium neon laser in many applications, conveying many benefits due to its superior ruggedness and compact size. This is to insure good thermal contact between the laser diode and the body of the module. The coating on the module casing is insufficient to provide substantial electrical isolation, therefore the module casing should not be connected to the negative supply or to a negative earth. One of the most common causes for diode failure is overheating. The life expectancy of the diode will be reduced if it is operated outside of the recommended temperature specification. Normal mounting of the module should be adequate, but additional heat sinking may be required depending on the duty cycle.
