WebThe net mechanical and optothermal effects from changing temperature can result in a change to the focal length of a lens. Courtesy of Edmund Optics. When exposed to extreme or changing temperatures, uneven expansion of the materials can cause optical elements to tip, tilt, and become decentered along the optical axis (Figure 4). Figure 4. WebMay 15, 2024 · The optothermal effect, which converts photon energy into heat, is now widely used in microfluidic systems for various applications. For example, under laser illumination, a surface bubble can be generated at the interface of the liquid and the laser-absorbing surface.
