Laser Host Heatsink

Aluminum Heatsink

Aluminum Heatsink can be unanodized or in black, green, blue, red anodized.

Extended Copper Heatsink

Extended Copper Heatsink improves thermal transfer and keeps your diode running cooler than aluminum.

Extended & Tapered Copper Heatsink

Extended and Tapered Copper Heatsink provides more mass and better cooling as well as more room below the heatsink for the wiring and driver. Also capable of running full-length modules.

Custom Heatsink
- +

Custom Heatsink - If you are using a custom heatsink, this item is worth 10$ so multiply by how much your heatsink cost.
