Re: Leica DM2500 condensers

My problems with 5x magnification mostly have been solved by adding a diffuser from a higher model (DM6000) (it was put into the universal condenser to one of slots) but there is a price - it takes away a huge amount of light. However, I use this diffuser with all magnifications during my routine wo...

Re: Leica DM2500 condensers

Relative to the comparison of 30w vs.100w Recall the intensity is proportional to the square of the distance the lamp is from the object. The 30w lamp is located right under condenser on the DM3000 while the DM2500 has the lamp house mounted on the rear of the scope, some inches away. It would be d...

Re: Leica DM2500 condensers

Have you tried lowering the condenser a little on it's track and closing the iris diaphragm some? Yes, I have, but it doesn't work. It would be too impractical anyway. Another option is that most condenser systems have some way of putting decondensing lenses into the light path. Your condenser, eve...

Re: Leica DM2500 condensers

1) Low power images are often problematic since while the apparent depth of field is great the depth of focus is small. It can take extreme care to get decent photographic images -- and more pixels also required to resolve the detail. This might account for part of your frustration? In particular, ...

Re: Hello all micro people.

What issues are you having with the Leica? I’m curious as I have least experience with Leica among the major manufacturers. I use an Olympus at home. The main issues run on adjusting a tailor-made condenser so that I don't have to switch its head back manually while using low magnifications and don...

Re: Leica DM2500 condensers

Thank you very much! My first application is cytology and histopathology which requires nothing more than brightfield (I often change between 5x and 10x and this is why I don't like removeable head!). Pathologists don't use other techniques and as far as I know are not familiar with them. BUT (last ...

Leica DM2500 condensers

Hello everybody. I have just bought Leica DM2500, nevertheless it doesn't meet all my expectations as they were specified ans accepted by Leica sales representative before the transaction. A condenser I have (Pol Universal Condenser UCA/P) requires switching back a moveable head for objectives 5x an...

Hello all micro people.

Welcome from Poland. I am a pathologist and a microscope-user with over 10-year experience. I have worked with Olympus gear for years and was very happy with it but my new private microscope is Leica DM2500. Unfortunately, I have some issues with it and would rather I chose Olympus...
