Slip-On Post Clamps
Can be used for mounting either 1/4"-20 (M6) or 8-32 (M4) components (when using the SD1 counterbore adapter ring) onto our Ø1.5" Posts.

Cage Clamp Mounts
Allow cage assemblies to be securely attached in a horizontal or vertical direction to our Ø1.5" Posts using a quick-connect mechanism.

Post Mounting Adapters
Function as a mounting platform on to out P-series post. Offers an array of 1/4"-20 (M6) and 8-32 (M4) tapped hole and counterbore combinations.

A response from Adam at Thorlabs to n.kunst: The measurements in the pdf of the MA4/M are correct. Unfortunately, this product would not fit on the T12XYZ/M. We could make a custom version that would align two of the tapped holes to the spacing of the T12XYZ/M for compatible mounting. Another option, if you do not need 12.7mm travel, would be to use the MS3. The MS3 contains two tapped M4 holes that will line up with the tapped holes on the MA4/M. My only concern would be the amount of equipment you would be mounting to the MA4/M. The vertical load capcity of the MS3 is 2.5lbs and the horizontal load capcity is 7lbs.

A response from Tyler at Thorlabs to nkaddy: Although we dont have a formal procedure, both the idea and the customers name are passed onto the design engineer. If the idea results in a new product or a redesigned product we often involve the customer in the testing of the prototype(s) and the customer is usually given the prototype version that is put into production. We chose to make this forum public because it was our hope that people like you would share their experiences with the science community. So even if the C1500 isnt redesigned, your idea may help other members of the science community improve their experimental setup. Thorlabs is not only interested in improving our product line, but in finding ways for us and our customers to contribute to the knowledge base of the scientific community.

To Tyler: Perhaps then you should have an incentives scheme, where if the feedback is useful you offer to make one of the items for the person suggesting it?

Hi acable, we ended up tapping an M2 thread into the side of the C1500 and added a spacer to the M4 thread projecting from the front so that the opto-mech can be tightend with the wheel still able to move freely. Once in position, an M2 screw in the newly tapped thread locks the wheel. I also tried thrust washers, they were OKish but not as effective and definately not set and forget.

The way i use the C1500 actually allows a piece of opto-mech with a tapped hole (#8-32 or M4) to be rotated to any orientation. I snug the mount down to the C1500 but leave it just loose enough to rotate, once i have the orientation i want i then use a 5/64" hex wrench inserted into one of the side holes on the locking wheel to full tighten the device. While this takes two hands, the result is a very stable mounting arrangement that allows the mating optical mount to be secured at an angle.

I like the idea of the C1500 but was disappointed to find that the wheel doesnt rotate once the mount is fixed into place. If you had a mount that would fix first and then could be rotated with the four holes actually providing locking screws I think youd have a better product.
