The tunable prism is a tunable wedge that allows to tilt two optically flat and AR coated glass windows with respect to each other. The two glass windows are held together by a bellow structure that is filled with a low dispersion clear optical fluid. The core element can be integrated with a large variety of actuation principles such as mechanical or motorized lead screws, voice-coil and piezo actuators.
The following table outlines the specifications of our standard tunable prism core element for a particular fluid. Cover glass coatings and fluids can be adapted on demand.

 The following table summarizes the main specifications of the TP-12-16:
