Compact 5-Axis Pitch, Yaw, and Translation Stage
5 Degrees of Freedom
The PY005 stage provides five axes of adjustment in an compact package measuring 2.36" x 2.15" x 1.08" (59.9 mm x 54.7 mm x 27.3 mm). It has five 100 TPI actuators for adjusting the top platform's pitch, yaw, X, Y, and Z positions. Two actuators together control the yaw and Y-axis position, two actuators together control the pitch and Z-axis position, and a single actuator controls the X-axis position. The actuators have a 5/64" (2 mm) hex for adjustments with a hex key or our HKTS-5/64 hex key thumbscrews.
The translating top platform of the PY005 has a variety of mounting holes and taps, as shown in the drawings that can be accessed by clicking on the icon in the specs table to the right. These holes allow the platform to be used for many different applications. For instance, the eight 8-32 (M4) tapped holes and the #8 (M4) counterbore on the underside of the top platform, accessible from the bottom of the stage, allow optic mounts and other optomechanical components to be mounted on the platform, as well as the PM5(/M) stainless steel clamping arm. The eight 6-32 (M4) tapped holes are compatible with our PM3 and PM4 clamping arms (sold below). The holes are positioned so that the setscrew of the clamping arm is centered over the top platform. The two 4-40 (M4) tapped holes allow Ø1" optics to be mounted in our 30 mm cage optic mounts (Item # B5C1, B5CT1, or B5CT2).
Additional 6-32 (M3) holes make the platform compatible with our FT-EOMA bracket and MMP1(/M) top platform (both sold below) for compatibility with our EO modulators and 3-axis flexure stages, respectively.
The base of the PY005 has two counterbored 1/4" (M6) slots, as shown in the photographs below, for mounting the stage to an optical table or to the mounting accessories sold below. The mounting accessories are for general use and also offer enhanced compatibility with our EO modulators and 3-axis flexure stages. See below for details.
The PY005 is a compact stage with five degrees of freedom. Two actuators adjust the yaw and Y axes, two actuators adjust the pitch and Z axes, and a single actuator adjusts the X axis. A variety of mounting holes are provided on the stage's top mounting platform for compatibility with many of our optomechanical components, including the mounting adapters sold below. A diagram of the mounting holes can be accessed by clicking on the icon in the Specs table in the Overview tab, above.

PY005 with PY005A2 Pedestal Base and MMP1 Top Plate Used with a 3-Axis Flexure Stage for Fiber Coupling
Our EO Modulators Can Be Mounted Using the FT-EOMA Bracket and PY005A1 Base (Left) for a 2" (50.8 mm) Beam Height or Directly to the PY005 (Right)
Mounting Base and EO Modulator Adapter
The FT-EOMA adapter allows our free-space electro-optic (EO) modulators to be mounted to the stage. When the PY005A1 and FT-EOMA are used together, the optical axis of the EO modulator is positioned at a height of 2" (50.8 mm) from the optical table. An EO modulator can also be mounted directly to the PY005 using the #8 (M4) counterbore accessible from the bottom of the stage. This counterbore is accessible even when the PY005A1 is mounted to the bottom of the stage.

Clamping Arm Extension Posts with Metric Indicator Groove
Thorlabs' Clamping Arms provide clamping force to secure optics to our kinematic platform mounts and V-clamps. The PM3(/M) accommodates optics up to 0.97" tall and features a 0.69" center-to-center distance between the post and the nylon-tipped setscrew that holds the optic. The PM4(/M) accommodates optics up to 1.61" and features a 1.16" center-to-center distance between the post and the nylon-tipped setscrew. The maximum optic height of the PM3(/M) or PM4(/M) Clamping Arms can be extended using our PM3SP(/M) or PM4SP(/M) Extension Posts, respectively. These extension posts are identical to the posts included in each complete clamping arm. Each clamping arm features 6-32 (M4) threads. The PM3 and PM4 can be mounted in 8-32 tapped holes by using the AS6E8E thread adapter, which features internal 6-32 threads and external 8-32 threads. The thread adapter is designed with the same outer diameter as these clamping arms and extension posts for seamless integration.
The PM5(/M) clamping arm is made entirely from heat-treated stainless steel, which helps maintain stability in fluctuating temperatures and provides vacuum compatibility. This clamping arm is recommended for use with the POLARIS-K1M4(/M), but it can be used with any platform mount that has one or more 8-32 (M4) tapped holes. The PM5(/M) can hold optics up to 1.65" tall, and the distance from the post center to the contact point that holds the optic is 0.90".
Each clamping arm is attached to its post using a flexure mechanism that locks with a 5/64" (2.0 mm) balldriver or hex key. The setscrew on top of the clamping arm also accepts a 5/64" (2.0 mm) balldriver or hex key in order to clamp down on the optic. The post includes a through hole which can be leveraged for added torque when tightening down the post. Please see the diagram above for additional information.
