About

Whenever high power lasers are used, removal of the created heat can be an issue. Copper with its very high thermal conductivity helps with this challenge. Cool Copper header is suitable for use in Gesture recognition applications, Pico projectors, LiDAR, Automotive headlights etc.

Product features

  • Thermally-conductive copper heat sink or slug brazed on to TO base.
  • Copper shape can be customized.
  • High transverse positioning accuracy better than ± 0.03mm (< < 2.0°).
  • Efficient heat dissipation with the guarantee of hermeticity.
