Handling C-Mount Laser Diodes
Proper precautions must be taken when handling and using C-mount laser diodes. Since these laser diodes are sensitive to electrostatic shock, they should always be handled using standard static-avoidance practices. Additionally, these lasers do not have a built-in monitor photodiode and should be used with a high-quality, constant current driver specifically designed for use with laser diodes. For constant power mode operation, please see our TO-can, pigtailed, and butterfly laser diode offerings in the selection guide to the right for options with monitor photodiodes.
Unlike TO can and butterfly packages, the laser chip of a C-mount laser diode is exposed to air; hence, there is no protection for the delicate laser chip. Contamination of the laser facets must be avoided. Do not blow on the laser or expose it to smoke, dust, oils, or adhesive films. The laser facet is particularly sensitive to dust accumulation.
During standard operation, dust can burn onto the laser facet causing tiny “specs” that will lead to premature degradation of the laser. If operating a C-mount laser for long periods of time outside a cleanroom, it should be sealed in a container to prevent dust accumulation.
As with all laser diodes, temperature regulation is necessary for sustained, reliable, long-term operation. The back face of the C-mount package is machined flat to make proper thermal contact with a heat sink. However, do not use thermal grease with this package, as it can creep, eventually contaminating the laser facet. When making electrical connections, care must be taken if soldering to the wire lead. Solder with the C-mount already attached to a heat sink to avoid unnecessary heating of the laser chip. The flux fumes created by soldering can also cause laser damage, so care must be taken to avoid this.
SAFETY INFORMATION
The laser light emitted from this laser diode is invisible but may be harmful to the human eye. Avoid eye exposure to the beam, both direct and reflected. Products are subject to the risks normally associated with sensitive electronic devices including static discharge, transients, and overload. Please ensure ESD protection prior to handling the products.
