Response from Tim at Thorlabs to Silvio: The maximum runout of the LNR50 is +/-10um over its full 50mm of travel and this is tested on every one produced. Your conversion to 200urad appears correct. We will clean up our web presentation to make the performance differences more readable.

Response from Jeremy at Thorlabs: The 2 "steel cylinders" are the alignment pins. These are used when you need to assemble more than one LT1 into an XYZ configuration.

product looks great. Along with said product, I received a small envelope with a collar intended to collapse the brass collet on the stage. Also inside said envelope are 2 small steel cylinders, diameter 1/8" X 1/4" long. What are they for?

Dear Sir or Madame Dispite the feedbacks I still don't understand what the quality difference of the LNR and LT1 stage is. The runoff of the LNR gives an angular deviation of alpha<10*10^-6/(50*10^-3)=200urad over the full range. The angle given in the reply of the feedback gives a run off of 4*10^-6*50*10^-3m =200nm which would be amazing and much less than the specs given. Also if I use ratio of the angles for the LT1 and LNR given in the comment I get a run off for the LT1 that is 150/4*10 um =375 um, which is realy bad. Could you explain how you convert the run off and the angular deviation? Kind regards, Silvio Koller

Response from Tim at Thorlabs: Thank you for your feedback. An additional LT102 (and possibly an additional tap/adapter depending on your mounting requirements) may serve your purpose. I will contact you to discuss the placement of the load and some of the options that may be suitable for your setup.

Hi, I am interested in an XYZ configuration, for a load of max. 5kg. The load needs to be mounted in such a way such that the mounting axis (the screws used for the mounting) are perpendicular to the surface of the optical table. I am considering using the LT3 with an additional right angle bracket attached on the Z-stage (the load would be mounted on the free side of the bracket). Would you recommend the LT3 for this load and mounting setup? Also, what bracket and possibly adapter plate would you suggest I use for this? (The load is mounted through a 1/4-20 mount and requires about 3x3 inches space). Thank you in advance for your assistance!

Response from Javier at Thorlabs to last poster: Thank you very much for your feedback! We will revisit the design of the LT1 2" translation stage to determine the best way to fit a threaded or a barrel mounted micrometer. Please contact us at techsupport@thorlabs.com if you would like to follow up with us.

Disappointed to receive this item and learn that this stage does not allow replacement of the lead screw with a micrometer and that the screw mount and seat are not reconfigurable. It looks like it will be easy to machine out the screw mount to fit a threaded mic.

A response from Adam at Thorlabs to tshiflett: We can offer a LT1 with a micrometer as a custom made product. I will contact you directly to see if you are interested in this option.

Hello, my company bought the LT1 a few months back. It works good but they can me to make a change. They want to be able to tell the distance that it is moving. Is there any vernier scales or something that you can recommend to do this. Todd

A response from Adam at Thorlabs to James: We can modify the hole on the LT1 to hold a 151-412ST micrometer. The lead time for this modification will be ~4 weeks. I will email you directly to see if you are interested in a quotation.

I was wondering if one or all of the actuators of the stages in the LT3 can be changed for a micrometer?

A reply from Jens at Thorlabs: The runout of maximum 10um over the travel range for the LNR stage corresponds to a value of about 4urad, giving a considerably tighter specification then for the LT1 stage. I will work with our motion control team on spec table which will allow easier comparison.

I was trying to compare this stage with the Steel LNR stage with regard to travel straightness but I cant because the LNR straightness is shown as a runout and this one is shown as micro radians. I assume the LNR is better but maybe not and I dont want to pay more if I dont need to. Could you make the specs comparible. It just seems such an obvious thing to do unless you dont want to allow customers to compare.

A response from Ken at Thorlabs to benjamin_teokc: The standard LT1 is a right-handed version. We could possibly do a left-handed version but the price will be much higher since we have to make special top and bottom plates from scratch. If you are interested in a formal quotation, please send your contact information to techsupport@thorlabs.com and we will prepare a quotation for you.

I was wondering if there is a left hand as well as right hand version for product No. LT1?
