*All tests are under pulse condition 1000Hz, 10%D.C. with heatsink temperature 50℃. Operating current range is for reference at engineering stage in case the typical value is not ideal for module application. Within such a current range, an acceptable PCE can be maintained, though most parameters are subjected to change if operating current is different from the suggested typical value.
Typical Performance Curves at 50°C
Far Field Beam Profile
Beam Divergence Angle (FWHM) in the long axis is about 72degree and in the short axis is about 58degree.

Shipping Instruction
The modules are shipped in tape & reeling packaging or Gel-boxes.
Note: No responsibility is assumed for the use of these products. The products canemit Class IV radiation and must be operated with extreme care. Avoid directly viewing the laser beam or exposure to specular reflections. Proper eyewear must be worn at all times when operating. VCSEL Chip in the modules are electrostatic-sensitive device and proper ESD protection is required forhandling.
