Shipping Instruction

The diffuser modules are shipped on adhesive blue tape or Gel-Pak boxes.  

Copyright ©Vertilite.    Note: No responsibility is assumed for the use of these products. The products can emit Class IV radiation and must be operated with extreme care. Avoid directly viewing the laser beam or exposure to specular reflections. Proper eye-wear must be worn at all times when operating. VCSEL Chips are electrostatic-sensitive device and proper ESD protection is required for handling.
