Re: Rheinberg Filters

I was interested in ordering a set of Rheinberg filters such as these off of eBay to play with: But then read this article suggesting that the diameter of the inside color disc should specifically match the diameter of the condenser iris, which changes with each objective if you follow the author's...

Re: Looking for an Abbe 1.25 Nikon Labophot Condenser with DF stop insert

Yes I already have that condenser and I can make that my self with my 3D printer. Which I've already started designing. The reason why I want the other condenser with the slot is for that very reason. I could 3D print my own different stops using the dimensions of the DF stop it comes with. Also I c...

Looking for an Abbe 1.25 Nikon Labophot Condenser with DF stop insert

I can't seem to find a condenser that originally came with the Nikon Labophot. Apparently it had a Dark Field stop you could insert into the front.

Like this.

Re: Permanent Slide Mount Assistant DIY (3D printed)

I just find applying constant pressure over 2 hours (nail polish) creates no bubbles. Plus the added weight also requires much much less polish creating a very thin layer, almost rendering it invisible. Also with the right amount there tends to be no ooze on the edges of the cover glass.

Permanent Slide Mount Assistant DIY (3D printed)

This might be a little over engineered, but it's a good excuse to practice with my printer. It presses the cover slide down while the nail polish dries into a nice thin bubble free layer.

Thanks for taking the time and your test is fantastic, but I'm going even more basic than comparing high end lenses to high end lenses over time. This is more what I'm talking about.

So as a newbie who will upgrade his objectives slowly ($$$) in the future I've been learning about lenses.

So I've been searching "How to create a permanent slide"

I'm seeing Fructose, Nail polish and a few chemicals in which I can't remember the names of.

Thanks. I dont think im going to try and find anything to accomodate the illuminator. I just thought lighting a subject from above would be neat.

I contacted the seller and he agreed to a refund.

Re: Vertical Illuminator for Nikon Labophot question

Only if you want it to light up . . . :) Your epi adapter should also have a tube lens as well as a half-mirror in it, to adapt it to 160mm objectives. Otherwise, it is intended for a longer objective tube length, perhaps the Nikon 210mm (if I recall) BF (bright field)/DF (dark field) objectives. I...
