Hi All

I'm selling a freshly rejuvenated stabilized HeNe from Melles Griot

Its from 2007 and ballast resistor has been replaced by a genuine one from Sam Goldwasser who helped me diagnose and repair it

It locks in at least 6 minutes when last tested, and is rock stable at the milliwatt range by eye guess

I really need this money to fund some lab gear (true RMS multimeter is on sight)

The fiber output has been damaged before I've got it, but can be sawed off... there's still the standard right angle output when pivoting the beamlock

Beam spec 0.47mm at tube output, for more see http://www.sigma-koki.com/pdf/en/C040105.pdf

I'm asking for a decent price as it is a recent unit and in really nice condition despise the fiber coupler...

Perfect for holography as the spec will show, and in working order and locking is guaranteed!

Please PM me for any offer!

EDIT :

Spot picture was taken before reassembly, so it might need minor cleaning if a bit of bust has flown on the mirror
