Nice!

A LED lamp, but check what excitation wavelength you want to use.

since corrections only occur in the objectives. Eh, no, the condenser plays a part too. Anyway, who's the buyer for whom you claim this benefit? The professional market has no problem with the price of the supercorrected optics available nowadays. I don't see any interest from the amateur side for ...

Actually found a link to a HPLC detector using Olympus 40x objectives in Geissler ea (2016) Microchip HPLC separations monitored simultaneously by coherent anti-Stokes Raman scattering and fluorescence detection. (can be reached via booksc.org). No mention of phase contrast or apodization however. R...

Interesting stuff. If this is coming out of a machine, it makes more sense that it is a dry lens instead of an immersion lens? I'm sure you have tried that, but you never know. Might be part of a micro UV fluorescent detector in chromatography, with a quench of the direct light. Must be a micro cel ...

Definitely a step up from a normal achromat! 37 mm parfocality though, so needs refocussing when mixed with modern 45 mm objectives. 170 vs 160 mm is not really an issue for objectives, but for the rest of the scope (particularly eyepieces). As scarodactyl says, it is no match for a more recent (pla...

FWIIW, there has been a discussion on a german forum concerning an Olympus SWF trinotube that showed an uneven field in DIC, not due to the DIC unit. It was concluded that there must be a depolarizer installed in the head that has been removed. So you might want to check also the effect in polarized...

Film labels aren't really an option. Most of my slides are premade, many which are "vintage", featuring handwritten labels. It's sad to see them ruined, so I am as careful as possible when I clean them. Sure! You can protect them with hair (varnish) spray. That's how I made resistant labels in the ...

Is there a good way to clean slides? I don't like ruining the labels. :( Polyester film based labels (eg dymo band) works great, all be it a bit coarse in printing with this cheap kind of printers. And properly degrease slides before sticking labels and rub them then thoroughly on the glass. They c...

sounds great Par, but how do you suggest to make yourself the DIC prisms?

Satisfied, Viktor?

Hi, René - Well, higher magnifications are OK on the .55 NA DIC condenser for the Diaphot, but the results are inevitably limited and there isn't much point in using the scope as configured for that, to my way of thinking. If nothing else, using high NA objectives on the Diaphot requires super thic...

[Given the NA .52 limit of the Nikon DIC LWD condenser, and given the likely need/desire to use LWD objectives, high magnification objectives are of limited usefulness on the standard Diaphot. Don't dismiss high mag objectives for this reason. I've worked routinely on an Olympus IMT2 with 0.55 cond...

Nah, I was too fed up with exchanging the condensor top the whole time, and that in the lower, most used range. Sold it. But I know many people very happy with the older Zeiss DIC. A dutch microphotographer told me he loves it for its subtle effect. Kept the Zeiss Standard stand by the way. I think ...
