This piezo module attaches to the grating pivot arm (Littrow) or mirror pivot arm (Littman) via its M12 x 1.25 threaded housing to provide fine wavelength tuning of a Tunable Laser Kit. The standard tuning actuator is a Z812 DC servo motor, which offers 12 mm of travel and a minimum incremental movement of 0.05 µm. The piezo module is used in tandem with the Z812 tuning actuator, allowing the user to access the full tuning range, while also having the ability to finely tune the wavelength. The TLK-PZT1 has a BNC connector for use with Thorlabs open-loop piezo controllers.
