Stainless steel optical mounts with piezoelectric adjusters provide long-term alignment stability in closed-loop systems. These piezoelectric-driven adjusters feature power-off self-locking, making them ideal for applications requiring long-term stability. These mounts offer a wide angular adjustment range of ±4°, with a typical step size of 10-30 nm. Using the accompanying piezoelectric motion controller and software, the single-step size can be flexibly adjusted within approximately ±20% of a 10 nm reference value. The piezoelectric actuators come with knobs for manual adjustment. These piezoelectric mirror mounts include a controller, two PTP09 piezoelectric screws, and a piezoelectric screw actuator kit for the controller (sold separately by our company).

Compared to non-MT stainless steel series mounts, the MT stainless steel mounts integrate matched piezoelectric-driven adjusters and a body design that offers better durability and thermal performance. The combination of flexure springs and set screws secures the optical element without being affected by temperature, unlike rubber-tipped screws which are more sensitive to temperature fluctuations. The minimum optical element thickness is 2 mm. The set screws for adjusting the flexure springs are adjusted using a hex key; mounts with Ø1-inch and Ø2-inch apertures are adjusted with a 2 mm hex key. We strongly recommend using a torque wrench to secure the optical element to prevent surface deformation and improve thermal stability.
The side of the optical mount features M4 countersunk mounting holes. Two M4 thin-head hex screws and one each of 2.0 mm and 2.5 mm hex keys are included with purchase.
