Abstract: In some implementations, an optical device may include a base with a first coefficient of thermal expansion (CTE). The optical device may include an opto-mechanical component with a second CTE attached to a surface of the base via a solder layer. The first CTE and the second CTE may differ by greater than a threshold amount. A spacer may be disposed within the solder layer to attach the opto-mechanical component to the base.
