The minimum incremental movement is based on half a graduation of the micrometer scale.
The load capacity when the stage's base is mounted on a horizontal surface. The max load capacity is different at certain points of the platform. Please click here for more information.
The load capacity when the stage's base is mounted on a vertical surface. This load capacity will depend on the stage's orientation, the positioning of the load on the top platform, and the distance of the load from the platform. The load data provided is approximate and meant as a guide only.

Features

Micrometer-Operated Pitch and Yaw Adjustment
1/4"-20 (M6) Tapped Holes with 1.0" (25.0 mm) Spacing
Combine with Linear Stages to Add Rotational Adjustment
0.98" (25.0 mm) Deck Height

Black Anodized Aluminum Construction

This High-Load Pitch and Yaw Platform provides ±2.5° of adjustment in pitch and ±4.05° in yaw. It is designed for use with up to 5 kg (11 lb) loads, such as lasers, cameras, and 3-axis stages. The actual maximum load will depend on the positioning of the load on the platform (see the Specs tab for more details). The top platform is equipped with an array of 24 1/4"-20 (M6) threaded mounting holes on 1" (25 mm) centers.

PY004 Stage Fitted with Z812B DC Servo Actuators
(Sold Separately)

The high-resolution micrometers incorporated into the stage are marked with a vernier scale and provide positioning accuracy within 9 arcseconds in pitch and 16.2 arcseconds in yaw. Turning the micrometers gives 0.25° of pitch and 0.45° of yaw per revolution. Additionally, this stage is compatible with other micrometers with a Ø3/8" mounting barrel. The stage can also be motorized using our 1/2" travel actuators with Ø3/8" mounting barrels, such as Thorlabs Z812B DC Servo Actuators (shown to the left) or ZST213B Stepper Motor Actuators.

The base of the pitch and yaw platform is provided with a series of through holes for attachment to metric or imperial optical tables and breadboards. These holes allow the unit to be mounted with the top platform holes in line with the worksurface hole pattern or midway off the table's hole pattern. The unit can also be secured at any arbitrary position by using two CL6 table clamps.

Does the PY004/M have a vacuum compatible equivalent?

Response from Charles at Thorlabs: Hello and thank you for contacting us. Some of our stages can be made vacuum compatible on request and the PY004/M is one of them. We will reach out to you directly regarding the current lead time and pricing.

i want to place that mount in vertical position and the payload on the mount will be around 5Kgs . it can carry the mount load of 5kgs in vertical direction Regards, Saikiran

Thank you for your inquiry. When mounted vertically the load capacity depends on the load distance from the platform and the load it self. Mounted vertically the maximum load the stage could handle is about 1.8kg approximately and the off axis distance from the platform being 30 mm.

I'm having the same issue as Lawrence (last post below) in understanding how the linear micrometer movement translates to rotation. I also calc that the minimum incremental values (per half division) are twice those stated. Example below is for pitch, but yaw calculation is also wrong. 1 Rev micrometer = 0.5deg = 1800 sec 1 inc micrometer = 1800 sec/50 = 36 sec 1 half inc micrometer = 18 sec (vs 9 sec quoted on website) Can you clarify? Thanks.

Thank you for your inquiry. Due to the mechanism of the stage it wouldn't be a completely linear relationship but between micrometer movement and the rotation.There is a small acute distortion. This also depends how you measure - if the beam is going through the rotation center it will be perfect. In any other cases you will find another numbers as to the rotation of the beam you need to add the movement of the source. If you have any questions please dont hesitate to get in touch with your local technical support team

Yet another: Taking pitch on the PY004, minimum incremnental movement is given as 9 arc seconds based on half a division. But at 0.5 degree/rev = 1800 arcsec/rev = 36 arcsec/div. Min inc mov is thus 1/4 division. Am I wrong in assuming 50 divisions/revolution? (Note manual Fig 2.2 implies 100 divisions/revolution also).

Response from Ben at Thorlabs: Thank you for your feedback messages. The micrometer drives can be removed by loosening a single M3 screw for each actuator, and installing an appropriate Ø3/8" mounting barrel. There is no need to return the stage to be retrofitted. The micrometer itself has a 10µm per division travel, and has a 13mm range. Finally, your calculation does appear to be valid, and I will contact our engineers to clarify this further. I will contact you directly with the results of these discussions.

Another question: How much actual travel/revolution is occurring with each micrometer in the PY004 (information needed when looking at motorized options). Thanks

lawrence.berg (posted 2015-09-15 10:01:08.143)

Can the PY004 be retrofitted with the motorized micrometer options discussed by the end user? Or must the unit be sent back for retrofit?

Does the PY004 have a locking feature? or do you have a comperable fitures that does

cdaly (posted 2014-04-09 05:16:51.0)

Response from Chris at Thorlabs: The PY004 does not have a locking mechanism. While we do have other pitch yaw stages, I'm afraid none of these have this feature either.
