Re: Comparison of AmScope's Plan & Non-Plan Objectives

Hmm, looks significant to me, especially for the 40x, where the central part of the image is improved within the area most concentrated-upon and indeed covered by a camera's FOV.
Almost seems to be a case of the higher the mag, the more noticeable the improvement.

Re: Leitz PL 1x

Cripes old chap - you're right! Completely forgotten that saga. I wish I'd known then what I know now - an old story that! I wonder if I remembered to swing out the collector lens, probably did but that may have made a difference if I hadn't. Must have a look through my images for some sort of recor...

Re: Leitz PL 1x

I never found a 1x - and a while back now moved over to Olympus (the shame...... :oops: ) as I wanted to move to the newer generation/s of optics and I had a little spare money. My Leitz was a beautiful Orthoplan - a fantastic 'scope with beautiful optics - some of the type that I can't even dream o...

Re: Leitz PL 1x

If I were you, I'd buy them both for those very reasonable prices and worry about the logistics later. The 'special' condenser does occasionally appear for sale and as the Leitz has a slide-in mount it takes only a second to swap-out the std one and of course to turn the knob that swing's the built-...

Re: Olympus objectives

As above - Plan is UIS1 and Plan N is UIS2 - a coating difference I believe. I think the 'CN' designated those fitted to the CX range, the 'just N' for the BX series. I've compared both 'CN' and 'just N' on the same 'scope (BX40 and BX50) and there's absolutely no difference either by eyepiece of ca...

I'd say Michael has the jist - I suspect that as Kohler is defined primarily as uniformity of field illumination, rather than the accepted means by which it's achieved (i.e. field diaphragm and condenser height)... The LED may be deemed to give a uniform field, regardless of it's diameter? The corre...

Re: Features on the Head of a Dandilion

Hi, which part of the Dandelion are these from? It's a little hard to make-out so close-in.

May I ask what equipment you're using to take images, there may be a way to make them a little clearer.
