Abstract
A light detector includes a cooling device between a photomultiplier tube (PMT) device and a heat sink. A thermally conductive shield encloses the PMT device and the cooling device and is in thermal contact with the heat sink such that the heat sink transfers heat to the shield. The light detector may be included in sample analyzing apparatus configured for making optical measurements of a sample.
