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 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 translating top platform of the PY005 has a variety of mounting holes and taps that can be seen by clicking on the info icons in the tables below. 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 (sold below) for compatibility with our EO modulators.
For use with our 3-Axis Flexure Stages, we offer the PY005-K1(/M) adapter kit that includes a pedestal base and flexure top plate. This kit has an overall deck height of 2.46" (62.5 mm) to match the deck height of the stages.
We also offer mounting bases to mount the PY005(/M) onto optical tables or breadboards.
The PY005 is a compact stage with five degrees of freedom. Two actuators adjust the yaw and Y-axis, two actuators adjust the pitch and Z-axis, 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 info icon in the table above.
The PY005-K1(/M) includes a PY005(/M) stage, a PY005A2(/M) pedestal base (available separately below) and a top plate that give the PY005 a 62.5 mm (2.46") deck height. The top plate features 8-32,
The PY005A1(/M) and PY005A2(/M) mounting bases allow the PY005(/M) stage to be mounted onto optical tables or breadboards. Both bases include 1/4"-20 (M6) cap screws for mounting the stage onto the base.
The PY005A1(/M) has two slots for 1/4"-20 (M6) cap screws for mounting onto breadboards. Additionally, instead of using the slots, the base can be clamped onto the table using CL5 table clamps. The PY005(/M) can be mounted with the adjusters facing either the long or short sides of the base. When the PY005(/M) is mounted onto the PY005A1(/M), it has a deck height of 1.44" (36.6 mm).
The PY005A2(/M) has four slots for 1/4"-20 (M6) cap screws. When the PY005(/M) is mounted onto the PY004A2(/M), it has a deck height of 2.31" (58.7 mm)
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)
The FT-EOMA adapter allows our free-space electro-optic (EO) modulators to be mounted to the stage. When the PY005A1(/M) 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. The adapter allows the modulator to easily be taken off the stage without unmounting the stage from the optical table. An EO modulator can also be mounted directly to the PY005(/M) using the #8 (M4) counterbore accessible from the bottom of the stage. This counterbore is accessible even when the PY005A1(/M) 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, stages, 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 x 0.7) 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. This thread adapter has an outer diameter of 0.24", which is the same as the PM4SP extension post and the post included with the PM4 clamping arm. This allows the clamping arm to be adjusted across the seam between either post and the adapter. The smaller diameters of the included post for the PM3 clamping arm and the PM3SP extension post cause the thread adapter to act as a stop for the clamping arm.
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 or stage that has one or more 8-32 (M4 x 0.7) 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.
