Chapter 1: Overview
1.2.2. High Heat Load (HHL) Housing
The HHL housing is much smaller than the LLH and is completely sealed. The HHL
contains a Peltier junction and a PT-100 or NTC temperature sensor, which can be
controlled by the TCU (see section 1.3.1) or a local 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. The IR beam
is collimated through a chalcogenide glass lens and goes through an AR-coated ZnSe
window.
