Would it matter if the knob of the SM1ZA on top or bottom?

Thank you for reaching out to us with this inquiry. There shouldn't be a difference in performance, as long as the device is still translating horizontally.

Hello Thorlabs Team, I want to utilize 1" lenses in a 30 mm cage system. What are the advantages/drawbacks of CT1 and SM1Z ragarding machanical stability and vibrations? Many Thanks
llamb  (posted 2020-06-25 11:39:16.0)
Hello, thank you for contacting Thorlabs. The CT1 features a spring-loaded precision ball bearing decision, which is often more susceptible to external vibrations because of more internal components when compared to the simpler flexure plate design of the SM1Z. However, CT1 features a locking plate to secure a position, while the SM1Z does not. I have reached out to you directly to discuss which of these products will best suit your application.
user  (posted 2016-08-25 17:19:38.397)
The face of the CXY1 gives the impression you can rotate the optic (within the confines of the cage rods of course). Is this true? If so, can it rotate during translation as noted for the LM1XY? I see the "designed for pure X and Y translation" note but it's unclear if this is different than the LM1XY. Thank you.
milankie  (posted 2013-05-30 15:37:00.187)
are the differential screws in this product 1/4'' or 3/8'' wide? If they are 1/4'', are the ST1XY-M 3/8'' wide? most motorized actuators are 3/8'' wide, which is why I ask.
jlow  (posted 2013-05-30 16:47:00.0)
Response from Jeremy at Thorlabs: The differential drives have 1/4"-80 thread. The ST1XY-S uses a micrometer with Ø6mm barrel. It seems that you are looking for a motorized version of this. We could make a custom one using our Z806 motor. I will contact you directly regarding this option.

  • Compatible with 30 mm Cage Systems
  • SM1 (1.035"-40) Threading for Compatibility with Our Extensive Line of SM1 Lens Tubes

The CXY1QA XY Translation Mount is similar to the CXY1A mount sold above, but features a quick-release mounting carriage for easy exchange of components within a 30 mm Cage System. This mount provides ±1 mm of travel perpendicular to the optical axis of a 30 mm cage system. This translation is actuated by two 3/16"-100 lockable adjusters. The movable center carriage and magnetically coupled mounting carriage are internally SM1 (1.035"-40) threaded and directly accept Ø1" optics up to 0.39" (10.0 mm) and 0.20" (5.0 mm) thick, respectively, when secured using the included SM1RR retaining ring. The fixed back side is also threaded to allow SM1 lens tubes to be attached. The center carriage has been designed to offer pure X and Y translation.

The mount features engraved vertical and horizontal tick marks to use as an alignment aid for the movable carriage. A dot is engraved on both pieces of the mount to indicate the correct orientation of the quick-release carriage. Aligning the dots ensures the quick-release carriage is properly secured. The quick-release carriage also features a dedicated white space for denoting the optic that has been mounted within it (see the photo to the right). This allows for easy identification if more than one carriage is being used in a setup, as extra CXY1QF quick-release carriages can be purchased separately.

The translation mount also features four through holes for use with our ER cage rods. One side-located M4 x 0.7 locking setscrew in each bore can be tightened using a 5/64" (2.0 mm) hex key to secure a cage rod.

To remove the quick-release carriage from the mount when in a closed cage system, detach the carriage, rotate it 90°, and then take it out of the system. There must be at least 1.60" (40.6 mm) separating the edge of the quick-release carriage and the next component in the system to provide enough clearance during removal.

Translation of the Z-Axis Carrier Achieved by Rotating the Engraved Adjustment Dial

Thorlabs' CXYZ1(/M) Translation Mount features X-, Y-, and Z-axis travel and holds Ø1" optics, up to 0.39" (10.0 mm) thick, against the back lip of the mount using the provided SM1RR retaining ring. The XY functionality allows travel perpendicular to the optical axis, while the Z-axis functionality allows for compensation of focusing errors in applications such as fiber alignment or lens mounting. The optic cell has been designed to offer pure X, Y, and Z translation.

XYZ Translation Mount
Click to Enlarge

The Z-axis position can be locked by threading an SM30RR retaining ring (sold separately) onto the internal threads of the rear knurled knob. This can be done using the SPW607 Spanner Wrench.

The optic cell is internally SM1 (1.035"-40) threaded and is translated along the Z-axis by rotating the zoom adjustment dial on the back of the mount. The optic cell does not rotate during translation. An engraving is included on the knurled dial, indicating the direction that it must be turned for translating the optic cell forward and backwards. Laser-engraved tick marks spaced 0.25 mm apart are included on the optic cell for indicating the Z-axis position. The position can be locked using an SM30RR Retaining Ring (sold separately); see the image to the right for more details.

X and Y translation of the optic cell is actuated using the two 1/4"-100 fine adjusters, which can be locked using our LN25100 Locking Nuts (sold separately). Horizontal and vertical witness lines provide a reference for the XY alignment.

The mount has four through holes on 60 mm centers for use with our Ø6 mm ER cage rods, making it compatible with our 60 mm Cage Systems. Each cage rod mounting hole has two side-located 4-40 locking setscrews, which use a 0.05" hex key. The mount can easily be adapted to 30 mm Cage Systems by using the LCP02 Cage System Size Adapter. Two 1/4"-20 (M6) tapped holes are also provided on opposite sides of the XY adjusters for post mounting in right- or left-handed orientations.

Thorlabs also offers a 30-mm-cage-compatible XYZ translation mount for Ø1/2" optics, available here.
