Hello, we are designing a new optic setup for our lab, and if possible we want to have the optics in a cage system. We need a D-shape mirror our setup, but I have not found any D-shaped mirror Mount that fits into the cage system. Do you provide some kind of mount that allows to place a D-shape mount into a cage system? Best regards and thanks for your help, Alejandro

I'm wondering whether you make (or would consider making) a cage system compatible D-shaped mirror mount. I specifically would like to mount a 1" D-shaped mirror at a 45 degree angle within a 30 mm cage system.

I personally think there is a desperate need for a version of the kinematic 1/2 inch D shaped mirror mount in the Polaris style. There are two annoying qualities of these normal versions as designed. Keeping in mind that this is coming from someone who is making compact integrated optical assemblies that do not use pedestals or clamps. There is occasionally the need to integrate full angle control on a D shaped mirror, for instance when combining two close same wavelength beams in an interferometer configuration. The problems with this mount (KM05DR) are: 1) it has a thread rather than a counterbore, this means i cannot be mounted from the top, but only screwed in from the bottom, meaning I have to make a special adapter plate for it. 2) The beam height of the center of the mirror is not 1/2 inch as designed. 3) No dowel pin holes makes integration difficult (for setting the angle) Now you may say, that I should use the POLARIS-K05C4 Well now this is okay in some applications, but it has such long adjusters compared to many of the other polaris products and it takes up a lot of room on a board. Another minor annoyance is that if you center the beam on a glued D shaped mirror, another beam that you are trying to pass above it will interfere with the gluing ring. I was doing to have to take this to the saw and cut off half the glueing ring to clear the aperture fully for a passing beam. Thank you, Robert

Response from Javier at Thorlabs to mijaeldv: Thank you very much for your feedback! We are currently finalizing the details of the design of kinematic mounts for our 1/2" and 1" diameter D-shaped mirrors. The adjustability and range and foot print will be similar to that of our KM100 kinematic mount: http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1492. I will contact you with more information about this product.

Im currently doing research using these mounts. Due to the lack of adjustability, i have been forced to use a more complex and difficult set up for my experiment. It is definitely suggested that this mount should have a couple of knobs for adjustment, it would make it much more effective for any type application.

Response from Ken at Thorlabs to as468: Thank you for your valuable feedback. Your suggestion has been forwarded to our engineering deparment.

This D-mirror is very useful, but the mount could be improved. I would like to see an adjustable kinematic mount with more clearance near the sharp edge of the D-mirror. Let the sharp edge protrude beyond the mount a couple of millimeters, and give us knobs to turn. Preferably the knobs would be low-profile.
