A heatsink may include a base and a plurality of fins, configured to be disposed in an air flow, that extend orthogonally from the base. The plurality of fins may have at least one of a height, an inter-fin spacing, or a thickness that varies in a direction of the air flow.

Progressive heatsink

An opto-mechanical assembly includes a first thermal control element disposed on a region of a first section of an enclosure; a second thermal control element disposed on a region of a second section of the enclosure; and an optical element that includes a first portion and a second portion. The first thermal control element is configured to heat the first portion of the optical element and to cause the first portion of the optical element to be associated with a first temperature, and the second thermal control element is configured to heat the second portion of the optical element and to cause the second portion of the optical element to be associated with a second temperature. This causes a difference between the first temperature and the second temperature to satisfy a temperature difference threshold. Accordingly, this also causes a temperature gradient along an axis of the optical element to satisfy a temperature gradient threshold.

Dual thermal control element configuration for opto-mechanical assembly

An optical device may include an enclosure including an optical aperture and a plurality of optical components positioned within the enclosure, where the plurality of optical components are to emit and/or receive light through the optical aperture. The optical device may include at least one heating element or cooling element to provide an isothermal environment to the plurality of optical components, where the at least one heating element or cooling element is thermally coupled with the enclosure.

Isothermal enclosure with optical aperture

A method may include identifying, by a device, a set of components of an optical device. The method may include determining, by the device, a set of design criteria based on the set of components of the optical device. The method may include identifying, by the device, an initial heater configuration based on the set of design criteria. The method may include determining, by the device, a set of optimization parameters for determining a target heater configuration based on the set of design criteria. The method may include performing, by the device and based on the set of optimization parameters, an optimization procedure to alter the initial heater configuration to determine the target heater configuration. The method may include providing, by the device, information identifying the target heater configuration based on performing the optimization procedure.
