Hello, You should offer the USB connection cord for this micrometer head. It allows you to input the reading directly into any text cell on a computer without any additional hardware. The computer treats the micrometer head like a "keyboard". It's very handy. Regards Marty

Hello Marty, thank you for your feedback. I have posted your request on our internal product engineering forum to be considered for a future product release.

Dear Mr/Mrs, I would like to ask whether the manual vernier scale is metric or imperial? Best regards, Henk-Jan
YLohia  (posted 2019-09-20 09:51:55.0)
Hello Henk-Jan, thank you for contacting Thorlabs. The graduation marks are imperial on the DM713.

Hello, with 10.9mm radius the DM713 is too large to be compatible with a PT1(/M) as suggested in the application idea illustration. When a PT1/M is directly screwed on a table, the axis of the micrometer is 9.7mm above the table plane. That's a frustrating 1.2mm clearance issue... Best regards MG

Response from Jeremy at Thorlabs: To make this compatible, one would need to add the PT101 base plate to the assembly. I will get the application idea picture updated to show the assembly with the base plate.

It is stated that the DM713 has a 1um resolution, but the accuracy is +-2um. Is this correct? I do not understand how could the step resolution be smaller than the accuracy of the device. Also, how complicated it would be to swap the standard PT1 translation stage micrometer head with DM713?
besembeson  (posted 2016-03-02 02:19:11.0)
Response from Bweh at Thorlabs USA: Yes that is correct. The resolution relates to the smallest increment the actuator can be commanded to move based on the encoder and display. Due to friction, inertia and other motion control constraints, the actual displacement will be higher than this value, which makes the accuracy to be bigger. You can directly release the screw that locks the barrel of the standard micrometer and replace it with the DM713.

I have two question regarding the DM713: * what is the load capacity (N) in the translation direction * can the device be interfaced to a computer, e.g. via Labview?
pbui  (posted 2013-06-27 14:38:00.0)
Response from Phong at Thorlabs: The maximum load capacity for the DM713 varies according to the type of the load applied (static load or active load) and operating conditions (used as a feeding device or stopper). When used as a measuring device, the rated accuracy spec for the DM713 is guaranteed for load limits not exceeding 4 kg. There is a device that you can use to connect the DM713 to a computer to log measurement data. Since Thorlabs does not support the device, I would recommend you contact Mitutoyo directly regarding their USB Input Tools, USB-ITN.

Response from Tor at Thorlabs to cbrideau: Thank you for your request. I will contact you directly to determine whether we can provide this as a custom item.

Would it be possible to get a 2" travel version of this for use with the LNR50 TravelMax stage?

A response from Adam at Thorlabs: The DM713 is initially set up to give an absolute position. Although this is the inital setup, the user has the option of setting the zero point at any point along the travel of the micrometer to get a relative position based of your desired zero position. To set the zero position, all one has to do is move the micrometer to a position and press the zero button.
user  (posted 2010-01-20 14:07:34.0)
Can this give an absolute position or are all measurements relative to the position where the user last pressed the zero button?

A response from Tyler at Thorlabs to Tim: The drawing files you have requested are available under the "Drawings and Documents" tab. If you have any issues with the file formats available or in downloading the drawings please repost. Thank you for you interest in our products.

Do you have 3D models of your part no. DM713? If so, could you please email a 3D STEP file or a SolidWorks 3D model of the part? Thanks, Tim Marti

Thank you for pointing out that the presentation was missing the accuracy specification; it has now been added to the "Overview" tab. We are continually working to improve the content of our web pages in order to serve our customers and the value of user feedback in this effort is immense.

What is the accuracy of this device. Also the Soleil-Babinet compensator has an interface kit that works with the DM713, it would make sense to offer that with this device as well as the 1" micrometer that is also offered that appears to use the same electronics.

In the Related Products area you show the "1/4"-80 Adjustment Screws", please consider changing to "Fine Adjustment Screws" since this link takes the viewer to a page with all the adjustment screws (which BTW is very useful).
