Features

Five Axes of Lockable Adjustment

Pitch/Yaw: ±4° at 8 mrad/rev
X and Y Translation: ±0.04" (±1.0 mm) at 254.0 µm/rev
Z Translation^a: ±0.13" (±3.2 mm) at 318 µm/rev

SM1-Threaded (1.035"-40) Bore for Ø1" (25 mm) Optics up to 0.38" (9.5 mm) Thick
Two #8 (M4) Counterbores for Post Mounting
Compact Size: 2.54" x 2.54" x 2.10" (64.4 mm x 64.4 mm x 53.3 mm)

The K5X1 5-Axis Kinematic Optic Mount offers an optic cell that can be adjusted along 5 axes (pitch, yaw, and XYZ), each with a locking screw for stability. The translating cell has SM1 threading (1.035"-40) for attaching Ø1" mounted optics. The cell can also be used to mount Ø1" (Ø25 mm) unmounted optics up to 0.38" (9.5 mm) thick using the included SM1RR Retaining Ring, which can be tightened using an SPW602 or SPW606 Spanner Wrench (sold separately). The mount features engraved vertical and horizontal tick marks to use as an alignment aid for the mounting cell. For post mounting the K5X1 kinematic mount in a right- or left-handed configuration, two orthogonal #8 (M4) counterbores are provided. For information on the hex key sizes needed to adjust and lock the kinematic mount, please click on the Docs icon () below and select a drawing format.

For adjustment on all of the axes available with the K5X1 plus rotational adjustment, we offer the K6XS 6-Axis Kinematic Mount.

If higher adjustment resolution or control is desired, the three 1/4"-80 adjusters used for tip/tilt translation can be switched with DAS110 or DM22 Differential Adjusters.

Z-axis translation is accomplished by turning all three tip/tilt adjusters equally in the same direction.

Is it possible to screw in a lens tube from the back side (even when x/y adjustment is off-center)?

Thank you for contacting Thorlabs. Unfortunately, it is not possible to screw in a lens tube from the back of the K5X1.

a beefier (or 2") option that supports heavy 10x beam expanders would be great to have.

Hello, thank you for your feedback. I have posted your suggestion on our internal product engineering forum for further consideration as a future product in our catalog.

Are you planing to design a 2" version of K5X1 compatible with a 60mm cage system? Thank you.

YLohia (posted 2019-10-21 10:27:03.0)

Hello, thank you for contacting Thorlabs. We currently do not have any plans of offering a 2", 600 mm cage-compatible version of the K5X1. That being said, I have posted your request on our internal product engineering forum for further consideration as a future catalog item.

Would it possible to replace the two 100-tpi X,Y-translation screws with a compact motorized actuators, e.g., PIAK10?

YLohia (posted 2019-10-14 04:57:12.0)

Hello, thank you for contacting Thorlabs. Unfortunately, this is not possible as these XY adjusters feature a 3/16" mounting barrel while the PIAK10 has a 1/4"-80 Thread and 3/8" Barrel. We do not have any compatible motorized actuators for the 3/16"-100 thread.

This is good - can you please offer version with all metric parts?!

YLohia (posted 2019-06-13 09:19:46.0)

Hello, thank you for contacting Thorlabs. This part is counterbored mounting hole, so it is compatible with 8-32 threads as well as M4 threads. If there is a specific requirement you have regarding this, please reach out to us via email.

A greater X and Y translation would be great on this product. Thank you!

Thank you for your feedback! I have logged your suggestion in our internal forum for further consideration by our engineers.

Is the K5X1 mount compatible with the M4 or 8-32 screws? or both?

YLohia (posted 2018-07-24 08:17:50.0)

Hello, the K5X1 mount is compatible with both since it is a counterbored hole.

Hi My name is Glenn. Can 5 Axis kinematic mount use as C-mount on microscope ? I have a Zeiss 2 port phototube but with slightly different tilting angle of each port , I'm currently use fixed 1X C-mount , can I use this product to adjust? Thank you so much!

llamb (posted 2018-03-30 03:15:00.0)

Hello Glenn, thank you for contacting Thorlabs. The K5X1 has an SM1-threaded bore, to which you can connect a thread adapter (like our SM1A10) in order to adapt to C-mount threads. I will reach out to you directly to discuss your application further and see if this product is suitable.

Hello, We would really like to have something like this, only cage mountable. Might be worth putting on your internal forum if it isn't there already

llamb (posted 2018-03-04 04:57:53.0)

Thank you for contacting Thorlabs and for your feedback. I will add this idea to our internal product forum so that hopefully we can offer a cage mountable 5-axis kinematic mount in the future. I will also reach out to you directly to discuss this further.

Could you make a 2" version of K5X1? Thanks!

Dear Thorlabs team, is it be possible to purchase a two inch version of the K5X1 mount? Thanks.

besembeson (posted 2016-05-19 09:45:59.0)

Response from Bweh at Thorlabs USA: We don't have this at the moment and offering as a special will require modifying several components to accommodate 2". Please contact me at techsupport@thorlabs.com so I can discuss further your requirements.

ali.mahdavi (posted 2015-07-28 10:36:09.6)

regarding product K5X1 I just need half of this! rotation plus x-y mount any solution?

besembeson (posted 2015-09-23 06:38:21.0)

Response from Bweh at Thorlabs USA: We don't have a single solution at the moment. One way to achieve this now is to couple an XY mount such as the LM1XY to a rotation mount such as the CRM1 (or similar) using a coupler like the SM1T2 (or similar).
