The LDM-4982M is designed to accommodate an 8-pin mini-DIL laser diode module. The package sits on a temperature controlled cold finger above the ZIF socket. The mount includes case temperature control with a temperature range of -5°C to 85°C. This technical note describes the process of defining the maximum thermal load that the case temperature control can maintain at -5°C.The LDM-4982M mount can achieve a temperature control range of -5°C to 85°C at a maximum heat load of 1.5 W. At higher heat loads the minimum achievable temperature can be calculated from the equation above.
