Abstract
A system and method for dynamically controlling a temperature of a thermostatic reticle. A thermostatic reticle assembly that includes a reticle, temperature sensors located in proximity to the reticle, and one or more heating elements. A thermostat component that is in communication with the temperature sensors and the heating element monitors the current temperature of the reticle relative to a steady-state temperature. In response to the current temperature of the reticle being lower than the steady-state temperature, the heating elements are activated to preheat the reticle to the steady-state temperature.
