Additional Notes
• Data in the sheet are based on C-mount package heat sink testing.
• Do not operate the device above maximum ratings. Doing so may cause unexpected and permanent
damage to the device.
• Take precautions to avoid electrostatic discharge and/or momentary power spikes. A change in the
characteristics of the laser or premature failure may result.
• Proper heat sinking of the device assures stability and lifetime. Always ensure that maximum operating
temperatures are not exceeded.
• Observing visible or invisible laser beams with human eye directly, or indirectly, can cause permanent
damage. Use a camera to observe the laser.
• No laser device should be used in any application or situation where life or property is at risk in the
event of device failure.
• Specifications are subject to change without notice. Ensure that you have the latest specification by
contacting us prior to purchase or use of the product.
