A response from Jeremy at Thorlabs to Guy: Thank you for leaving your feedback online. I will contact you directly to discuss about this possibility.

Hi, Could you make a Nikon CFI-60 compatible version of OT1? Thanks guy

Response from Tim at Thorlabs: The RMS threads of the OT1 will hold the objectives snugly, and a typical set up can include a horizontal setup.

If I mount OT1 horizontally with 4 microscope objectives on it, can it hold them firmly without becoming loose?

Response from Buki at Thorlabs: Thank you for your suggestion. We will pass it on to our design engineers for consideration as we continue expanding our selection of microscopy accessories.

Any chance you can make a linear version of this ? Like a filter slider with position detents used in many microscopes. The accuracy may increase.

Response from Javier at Thorlabs to last poster: Thank you very much for your feedback. We apologize about the inconvenience with your objective lens turret. We really have not experienced significant quality issues with this product, so it is most likely an isolated case. However, we would like to discuss this in detail with you, so that we can ensure your satisfaction with the performance of this part. Please contact us at techsupport@thorlabs.com and we will gladly assist you.

I purchased one to mount inverted. However the repeatability of 2.5 um is not what I observe. The turret is simply too loose and by lightly tapping on the side of a mounted objective the image will move and not return to the previous position. I tried to tighten the spring-loaded screw but it was only stable when it was so tight, that it couldnt be moved at all. It feels miles away from quality turrets from either Zeiss, Olympus, Nikon, which are much more solid in construction. I am hoping that it was a manufacturing error and that my next one will be of better quality.

Response from Tyler at Thorlabs to Rick: Thank you for informing us of this engineering failure. We are happy to hear that your optics we not damaged when the part failed. I have arranged for a second OT1 to be sent to you for free and you should receive it on Monday morning. We will also review the construction of the OT1 in order to eliminate this design flaw. Thank you again for the feedback, we always appreciate it when our customers participate in making our products better.

I purchased one of these turrets. I liked the simple design and compact 4 positions. UNFORTUNATELY there is a BIG manufacturing flaw. The threaded sleeve that is attached to the angled suface which holds the objectives is actually GLUED on, not threaded or bolted. The picture on the catalog page for this item shows some fairly nice objectives which could easily cost thousands of dollars. Im sure the owner of those objectives wouldnt be too happy to see his objectives crash to the ground because the glue didnt hold his turret together. Luckily, I only had the turret mounted (no optics) when mine broke. Ive since had my machinist bolt these two parts together, something Id recommend be implemented in your manufacturers process. I do need another one of these items, Id like to get a good discount on the next one if possible, since it requires about $100 of additional machining cost to mount the sleeve properly. Please let me know if this is possible. thank you, Rick Logemann BioImaging Solutions 858-356-0669 PH
