FS: Melles Griot 20x Precision Beam Expander
I remembered I had a beam expander sat tucked in a box, earlier today when I was round at Robs. It was bought for a project over a year or so ago which never came into fruition; it's been sat packaged up ever since. So the plan is to sell it and put the cash towards a good cause (a nice blue 473nm for my RGB!)
The model no. is: 09 LBM 015
And it's a precision 20x expander.
It is in a new, unused condition. The new price was over £1,100

Here are the specs pasted from the catalogue:
Open to all decent offers via PM...Melles Griot precision laser beam expanders produce peak-to-peak wavefront distortion of less than l/4 in expansion ratios of 3#, 10#, 20#, or 30#. The Galilean design shortens overall length and improves performance by minimizing spherical aberration. A padded hardwood box is included for safe storage.
