Shipping Instruction

The unmounted chips are shipped on adhesive blue tape rings or Gel-Pak 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 viewingthe 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.
