Optics folks

I'm looking for a manufacturer of a mount suitable for use in the moving
mirror in a Michelson Interferometer.

I'm using 1" square mirrors and a 1" cube BS and tried using Edmunds
mounts for the mirrors, but I now realise that these are kinematic mounts
and are not really suitable for what I want. (I believe that they are
designed to provide the maximum freedom of movement with the minimum number
of 'screws'. It *is* possible to set up the MI with these mounts, but
adjusment in one plane is difficult.

Before I set off on a possibly expensive custom mount I thought I 'd check
and see if there is anything out there.

What I'm looking for is a mount that will allow precise 'X' translation
possibly with a differential type adjuster (to set the path length) together
with a '3 screws set in a triangle' type of mount to allow parallelism and
tilt (for controlled fringe formation) in the Z axis to be controlled.

Can anyone point me in the right direction? - a UK supplier preferred but
not essential

TIA

Iain,

I work at Thorlabs and can recommend a solution which you might want
to consider.

If you use our KC1 kinematic mount together with a SM1Z Z-Axis mount
you can have independent Z-axis and kinematic operation. The only
thing is that the SM1Z is for round mirrors only.
Using four ER rods (such as ER2) you could mount the SM1Z onto the KC1
such that when the angular setting of the KC1 is adjusted, the SM1Z
will move together with it. The SM1Z can then be used for the Z-Axis
adjustment.

Hope this was helpful, if I can be of any more help just let me know
by replying to this message.

Cheers

Sam
