Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please
Curtis, also, be aware this being an H series lab unit the beam quality isn't going to be as good as the F series which what this unit would be in if it had the better beam quality of TEM00. UK has this similar laser and I think it does TEM01.

Just as a heads up.

THe seller says the specs are:
model MGL-H593.5
used, in fully working condition, 50+ mW output
laser head + power supply complete.
from manufacturer specs:
TEM00 mode
beam diameter about 3 mm in aperture
polarization ratio >1:100
M2 factor <1,5
beam divergense <2 mrad
The ebay unit lists identical to the specs in the MGL-F-593.5 you posted so.... perhaps they were looking at the F spec. the H being no longer listed,on the CNI web site --who knows?
The H model 593.5 was eliminated and was a 50mW,60mW...80mW unit
see:
http://www.eforcelaser.com.au/PDF/MGL-H-593.5.pdf with a M2 factor of <2 and was TEM00
The F was listed as a 100mW to 150Mw unit with an M2 factor of < 1.5 and TEM00 see:
³È»Æ¹â¼¤¹âÆ÷£¬593.5 nm ¹ÌÌ弤¹âÆ÷ however, the data sheet of the time shows it as being 50mW to 150 mW same everything as today see:
http://www.eforcelaser.com.au/PDF/MGL-F-593.5.pdf
Probably CNI decided to offer only the F because it covered 50mW to 150mW range and there was little if any call for a slightly cheaper H covering 50mW to 80mW cost to make being about the same--only pennies different.
Either way is a good price @ min, bid $400 buy it now $600 if you just want to see a wavelength--- a 50mW MHL-F-593,5 is about $4000 retail see:

The beam quality or H is fine and is TEM00----beam quality makes no difference at all unless you have an actual purpose for the laser that requires it
