Features
- Mounts for Ø1/2", Ø1", or Ø2" Optics
- Internal SM05- (0.535"-40), SM1- (1.035"-40), or SM2- (2.035"-40) Threads
- Pitch, Yaw, and XYZ Adjustment
These 5-Axis Kinematic Optic Mounts have optic cells that can be adjusted along 5 axes (pitch, yaw, and XYZ). The 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.
The three adjusters for pitch, yaw, and z-translation can be independently locked 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 KC5X1(/M) mount requires F19SC1 locking collars (sold separately) to lock the X or Y axis and F25SC1 locking collars (sold separately) to lock the Z, pitch, or yaw axis.
The mounts feature engraved vertical and horizontal lines to use as an alignment aid for the optic cell.
The K5X05, K5X1, K5X2, and KC5X1(/M) kinematic mounts can be post mounted in a right- or left-handed orientation; 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). Item # KC5X1(/M) has two orthogonal 8-32 (M4 x 0.7) mounting holes, as well as four clearance holes to accommodate Ø6 mm ER cage rods for compatibility with our 30 mm cage systems.
For pitch, yaw, and XYZ plus rotational adjustment, we offer the K6X05, K6XS, or K6X2 6-Axis Kinematic Mounts.

(posted 2025-05-14 15:41:04.757) I want to connect K5X2 to GBE05-A.
I would like to ask you a few questions about this.
1. I tried to connect through SM2A30 and it seems that there is interference between SM2A30 outer diameter and K5X2 inside. (on 3D cad)
2. When I contacted SM2A30 and K5X2 and checked it in 3D, it seems that SM2A30 is over the K5X2 adjustment part.
I would like to ask if this is not connected.
In addition, I would like to get recommendation if there is a mount that can adjust the angle and displacement of GBE05-A.
Thank you. bmandal
(posted 2025-05-28 03:02:24.0) Thank you for contacting Thorlabs. I reached out to you directly via email to discuss your application, and the issue appeared to be the adapter SM2A30 being inserted into the wrong end of the mount K5X2. Jyong-Wun Chen
(posted 2025-02-11 15:48:02.21) Hi, I want to mount a ZBE1UVB beam expander on a K5X1 5-Axis Locking Kinematic Mount. Is this possible?
Can it be installed directly, or do I need to purchase an adapter? Also, is the load capacity of the K5X1 sufficient? jdelia
(posted 2025-02-19 01:54:21.0) Thank you for contacting Thorlabs. The K5X1 has an SM1-threaded aperture and the ZBE1UVB has external SM1 threads on both ends so it can be screwed in directly. I have reached out to you directly via email to discuss your application further. Sung-Dong Han
(posted 2024-08-27 14:51:19.083) Please tell me the load capacity of this product (K5X1) jdelia
(posted 2024-08-29 11:59:27.0) Thank you for contacting Thorlabs. While we have not characterized a load capacity for our 5-axis mounts, I have contacted you directly via email to discuss your application and whether the load you would like to mount would be suitable for these devices. Kai Kühnlenz
(posted 2024-08-20 12:04:05.37) Hello, in the drawing of the K5X05-Mount you can see the nominal values. Do they describe the case, where the K5X05 is shown in the middle of it's adjustment range? (So it's z-range is 4.6mm, does the drawing show the mount, when it's in the middel of that, at 2.3mm, so i can move it 2,3mm in either direction?) jdelia
(posted 2024-08-21 03:53:36.0) Thank you for contacting Thorlabs. Yes, you are correct. The CAD drawing shows the mount at its nominal position, meaning at the middle of its travel range. Jakob Reichel
(posted 2020-10-02 12:34:23.52) 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. Andrey Revyakin
(posted 2020-08-16 13:22:44.663) 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. user
(posted 2019-10-19 19:59:14.623) 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. user
(posted 2019-10-14 10:18:04.06) 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. user
(posted 2019-06-05 16:38:44.487) 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! mmcclure

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

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). |

The K5X05, K5X1, and K5X2 5-Axis Kinematic Optic Mounts have optic cells that can be adjusted along 5 axes (pitch, yaw, and XYZ). On the K5X05 mount, the three adjusters for pitch, yaw, and z-translation include locking screws, 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 Table 1.4 for appropriate optic sizes for each mount. The mounts feature engraved vertical and horizontal lines to use as an alignment aid for the optic cell.
The K5X05, K5X1, and K5X2 kinematic mounts can be post mounted in a right- or left-handed orientation; 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.

The KC5X1(/M) 5-Axis Cage-Compatible Kinematic Optic Mount has an optic cell that can be adjusted along 5 axes (pitch, yaw, and XYZ). The optic cell has an internally SM1-threaded mounting hole that accepts Ø1" optics up to 0.38" (9.5 mm) thick; the optic can be secured using the included SM1RR retaining ring, which can be tightened using an SPW602, SPW606, or SPW801 Spanner Wrench. Thicker optics can be accommodated by housing the optic in one of our SM1 Series Lens Tubes and then threading the lens tube into the front plate of the mount. The front plate also features engraved vertical and horizontal lines to use as an alignment aid for the optic cell.
Angular and z-axis adjustment are controlled by three 1/4"-80 screws, which can be locked using F25SC1 locking collars (sold separately). X and Y axis adjustment is controlled by two 3/16"-100 screws, which can be locked using F19SC1 locking collars (sold separately). All five adjuster screws can be actuated with a 5/64" (2 mm) hex key or ball driver (not included). Additionally, the three screws for angular and z-axis adjustment have knobs, located between the front and back plates of the mount, that can be turned manually or with a 5/64" (2 mm) hex key inserted into one of six holes on the edge of each knob, as shown in Figure G2.2.
Two orthogonal 8-32 (M4 x 0.7) mounting holes allow the mount to be post mounted in a right- or left-handed orientation. The mount also has four clearance holes to accommodate Ø6 mm ER cage rods for compatibility with our 30 mm cage systems. Once the desired position in the cage system is achieved, 5/64" (2 mm) hex locking setscrews on the rear plate can be used to secure the rods in place.
