High Heat Load (HHL) Housing

The HHL housing is a sealed collimated housing for CW or pulsed lasers. It is ideal for short-run integration and use in difficult environments. The HHL housing is much smaller than the LLH and is completely sealed. The HHL contains a Peltier junction and a NTC temperature sensor (model 10K4CG), which can be controlled by the TC3 or your own temperature control system. Heat dissipation is performed by thermal contact with its copper base; the heat dissipation capacity depends on the operation mode and environmental conditions.

• Size : 44.5 mm x 31.7 mm x 19 mm
• Sealed Package
• Base to be attached on flat heatsink surface (such as HHL Heatsink plate) using M3 screws
• Peltier cooled laser-stage inside, temperature differential up to 60°C
• Anti-reflection coated ZnSe protective window
• Internal lens
• Collimated free-space beam, divergence < 6 mrad
• NTC temperature measurement.
• Needs cool backplate (e.g. HHL Heatsink plate or other that can keep the backplate at +20°C with a 0.1°C/W thermal resistance.).
• Support lasers with dissipation < 12 W on NS, AN or AN-NSP mounts
