Hi gang,

I just went on a mini spending spree (all $65 worth) and ordered 3 objectives, a lomo 40 .95 apo, a Zeiss Jena 10 .30 ph and a lomo 40 .65 lumin phase. My question is about 'lumin', what exactly does the lumin part mean? I've seen numerous lomo objectives listed as either lumin, luminescent or lumin fluor and it seems to imply fluoride, to me anyway, but I've never seen it explained anywhere.

I'm in the process of converting my Zeiss over to all lomo, I'm still waiting for decent 20 .65 apo and 20 .40 ph to come up and saving for a 70 1.25 wi apo. I really like the old lomo objectives.

I believe it ("lumin") means the glass is suitable for fluorescence microscopy.

No, that "lumin" does not mean fluoride correction. It means the objective does not produce fake colors when used in fluorescence.

How/where did you buy those 3 objectives all for $65 though? That is a great price.

Consider LOMO water apo 65/1.1 as well. The good copy I have actually produce sharper and more contrasty diatom dotting image than my good copy of 70/1.23, and offers longer working distance.

Is this for your 'Zeiss hybrid AxioStandard'? Please see post at: viewtopic.php?f=24&p=55804#p55804

Thanks, at least now I know what lumin means :D

Fan, I managed to get them purely by luck. They are all from different sellers, the 40x apo went for $13 after 5 bids, I had an upper price of $35 on it and was not expecting to win. The Jena 10x ph had an opening bid of $10 and nobody else bid. The 40x ph L was listed as just a 40x .65 and I'm not sure why I even looked at it because I already have one, but photo #2 showed the phase Lumin stamps on the barrel with a buy it now of $13. The rest was shipping. The two lomos look like new condition.

I'll keep a lookout for the 60x 1.1

75RR, yes they are for the Axiostandard. One reason for wanting just Lomo, aside from their great performance is that they are 33 and DIN is 45, so I put a 12mm spacer under the stage to make up the difference in objective length. I use all sorts of odd lighting so I have a ring platform the condenser sits on when using it.

Hi all,

the jena phase 10x arrived and it's a bit odd, the phase ring is very faint and it doesn't phase very well, does anyone here have a jena phase objective and if so is the ring very faint on yours as well.
