Optothermal

Optothermal stability describes the rate at which an optical element distorts due to a changing thermal environment. A changing thermal environment can cause an optic to bend due to either 1) changing thermal gradients on the optic and a non-zero coefficient of thermal expansion, or 2) coefficient of thermal expansion gradients in an optic and an average temperature change. Therefore, optothermal stability is an issue for optics that are present in a changing thermal envi… WebJun 15, 2024 · The optothermal forces (TE force, depletion force, and electrokinetic force) exerted on particles are generated by a laser beam heating a functionalized plasmonic substrate immersed in a solution …
