The K5X05, K5X1, and K5X2 5-Axis Kinematic Optic Mounts have optic cells that can be adjusted along 5 axes (pitch, yaw, and XYZ). The three adjusters for pitch, yaw, and z-translation include locking screws on the K5X05 mount, while the X and Y axes are not lockable. The K5X1 and K5X2 mounts feature locking screws on all five adjusters.

The kinematic mounts' translating optic cells feature SM05 (0.535"-40), SM1 (1.035"-40), or SM2 (2.035"-40) internal threading for attaching mounted optics. A SM05RR, SM1RR, or SM2RR Retaining Ring is included with each 5-axis mount for securing unmounted optics. See the table below for appropriate optic sizes for each mount.

The SM05RR Retaining Ring can be tightened using an SPW603 or SPW603L Spanner Wrench, the SM1RR Retaining Ring can be tightened with the SPW602 or SPW606 Spanner Wrench, and the SM2RR Retaining Ring can be tightened using an SPW604 Spanner Wrench (spanner wrenches sold separately). Alternatively, the SPW801 Adjustable Spanner Wrench (sold separately) can provide an exact fit for any of the retaining rings used in the 5-axis mounts. The mounts feature engraved vertical and horizontal tick marks to use as an alignment aid for the mounting cell. The K5X05, K5X1, and K5X2 kinematic mounts can be post mounted in a right- or left-handed configuration; two orthogonal #8 (M4) counterbores are provided on the K5X05 and K5X1 mounts, while the K5X2 mount has three #8 (M4) counterbores on each orthogonal mounting surface (six total).

A 5/64" hex key or ball driver (not included) can be used to adjust the five axes of all the kinematic mounts. The K5X05 mount is equipped with 3/16"-100 knobless adjustment screws; the three screws used for pitch, yaw, and z-axis adjustment are lockable with a 5/64" hex key and feature Ø0.07" side holes for adjustment in tight setups. The K5X1 and K5X2 kinematic mounts include three 1/4"-80 adjuster screws with removable knobs for pitch, yaw, and z-axis adjustment, which can be locked with a 5/64" hex key. The X and Y axes on the K5X1 and K5X2 mounts are adjusted with two 3/16"-100 adjuster screws (the K5X1 mount features removable knobs on these axes) that can be locked with the included 0.035" hex key. If higher adjustment resolution or control is desired for the K5X1 or K5X2 mount, the three 1/4"-80 adjusters can be switched with DAS110 or DM22 Differential Adjusters. 

For adjustment on all of the axes available with the K5X05, K5X1, or K5X2 mounts plus rotational adjustment, we offer the K6X05, K6XS, or K6X2 6-Axis Kinematic Mount.

Is it possible to screw in a lens tube from the back side (even when x/y adjustment is off-center)?
YLohia  (posted 2020-10-02 09:48:59.0)
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.
YLohia  (posted 2020-08-19 09:32:03.0)
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.
user  (posted 2018-11-09 17:45:48.663)
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.
hfarah  (posted 2018-07-24 08:44:45.353)
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.
a.webber-date  (posted 2018-02-19 15:30:49.08)
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.
yanliu  (posted 2017-04-14 17:10:47.077)
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).
