Our mirrors consist of a reflective membrane placed over concentric electrode rings. Electrostatic actuation of the mirror surface is accomplished by applying a voltage between the membrane and the electrodes underneath. The focal length can varied from infinity (flat mirror) to less than 60mm, with full stroke settling times of less than 100µs. Our standard mirror diameter is 4mm, with other diameters available by request.
Our mirrors are available with up to five separate concentric electrodes, allowing shape of the mirror surface to be fine-tuned with a separate actuation voltage applied to each zone. The result is the ability to tune out spherical aberration in the optical system. Because the surface shape can be changed extremely quickly, real time aberration corrections can be performed to remove sample induced aberrations that change with focal position.
