Question about Science & Laboratory

1 Answer

Question #1. I currently use a Nikon Labophot 2 microscope with a 6 position nosepiece. On the Labophot 2, the 6 place nosepiece must be mounted facing forward, i.e., towards the user. A five place nosepiece could have been mounted in the usual reverse position. I'm a pathologist and this configuration makes it more difficult to manipulate slides because the objectives get in the way. Once, years ago, I was told that the Optiphot 2 allows a 6 place nosepiece to be mounted in the usual reverse position (i.e. facing away from the user). Is that true? ================================================== ==== Question #2. Would an Optiphot 2 with its 100 watt bulb have a more reliable light source than the Labophot 2? Sub-question: Any improvement in uniformity of field illumination with the Optiphot 2 over Labophot 2 at low power (4x objective) using the Abbe 1.25 condenser? (Right now with the Abbe in place I must add a second diffuser to even out the illumination. This is not true when using the achromatic swing out condenser with the 4x objective.) ================================================== ==== Question #3. Can a Nikon Optiphot 2 POLARIZING microscope (with its different condenser mount) be easily re-configured for brightfield by using parts from the stand of an available Labophot 2? Thanks.

    I'll have to look into LED bulbs. Didn't know they could be retrofitted onto the older platforms. How long do they last. My current scope burns them out faster than one would expect. A colleague has the same scope and his doesn't do that. It may be that mine is always brighter than his due to a polarizing lens (analyzer) in the light path on my scope, so the bulb wears out faster. I don't know. Thanks.

Wow that is an old ****** mid 80's and I wish I had one ;-]

I do not recall seeing a 5 position, I think it came with a 6 and there was a second optional 6 but do not recall seeing a 5.

This has a halogen bulb. You could replace with and gain better lighting/contrast etc with any of them.
There are led types and others. To be honest without any experience in what you need to see the best advice I can give is you may have to try more than one. The newer led ones will be much better but they vary in the wavelength so some light is whiter and some is bluer than others.

I never tried to swap parts so no definite answer for you. They are similar but you would almost have to just try it. As long as you protect the lenses and eye pieces and remember where everything came from and how it mounted (its not that bad to strip down and clean and overhaul a scope) You can try to mix and match the parts. With a digital camera and a notepad this should be a nobrainer to attempt.
