RE: [HAPS-L] Microscopes

We have used two solutions depending on whether I want active images being shown as I manipulate the scope or I want still images to insert in a class presentation.



1.                  It is possible to connect a real time video camera directly to either an LCD projector or TV.  You do need to match the video output of the camera to the viewing system but no software/computer interface is needed.  You also need to insure that the camera has a threaded front lens that can accept filters and purchase a an appropriate sized microscope camera adaptor.



Most video cameras have a composite video output (yellow plug) and most LCD projectors and TV’s have a composite video input.



2.                  Another simple solution is to mount a digital camera (a Nikon Coolpix 4500 works very well) to a microscope with a microscope camera adaptor (about $100-$150).  A 5mpix auto focus camera will produce very good jpg images that can then be used in PowerPoint for class presentations and exams.  Take the pictures with the camera then download them to the computer.



The microscope does impose the initial resolution limit and, of course, a better scope produces better results.  We have found that any decent scope has worked well.  It is most convenient if it is trinocular with a camera tube and has a mechanical stage.

Subject: [HAPS-L] Microscopes
We are looking to purchase a microscope to replace our existing digital microscope. These basically use a software (Motic Software) that projects histology slides via the computer and LCD projector on to a screen. We can capture the images and save them on the computers. We are not satisfied with the quality of the images which end up being very grainy. I believe there was one model with a camera mounted on the microscope that was demonstrated at HAPS. Does anyone remember seeing this and know what company made these?
We are specifically looking for suggestions (and costs if possible) for the various kinds of microscopes that might be available.
Additionally, we would appreciate comments about the various microscope manufacturers and affiliated software that have been proven in your labs. 


Any input would be helpful.



Thanks,

Nishi Mathew
