How to do Polarization Microscopy

Hello all,

I produced a video which may be helpful to those who are curious about polarization microscopy, or would like to get started themselves.

I have posted it on youtube: https://www.youtube.com/watch?v=XTHBrV8 ... oFYxRCTMYM

Re: Retrodiode LED conversion

I use one of their products on my Nikon S-kt. The product is good, but will second JGardner on the banding produced in photographs below 100% brightness. I however find the price point at ~$150 USD to be too high. It is after all an LED, 3D printed plastic housing, an aluminum heat sink and a bright...

Re: Olympus Short Barrel Plan Apo's on a Nikon L-ke

Hm. Thank you again to everyone who replied. The objectives arrived today, they are the short-barrel 160mm tube length plan apos. I put them on the Nikon L-ke, and the field of view definitely had trouble with focus, and looking through my Nikon H.K.W 10x produced significant strain to the eye. I su...

Found: Nikon Optiphot II

I am looking for a Nikon Optiphot II.

It is not necessarily required to have a nosepiece with objectives, but preferably it has a stage and trinocular head.

Please let me know if you have anything like this.

Thank you,

Olympus Short Barrel Plan Apo's on a Nikon L-ke

I am curious if these objectives are interchangeable. I am are that short barrels on older microscopes nearly always require compensating oculars. It seem that 'HKW' is required for my nikon objectives, and online queries of olympus oculars seem to be labelled 'WHK'. I ordered a 160mm tube length pl...

Wanted: Nikon S-kt Trinocular Head

I'm looking for a trinocular head. This was in a previous thread, and while I thought I had fixed the item, I can tell the damage to the prisms is greatly affecting the image quality.

If anyone has such an item, I would be interested in buying it for a reasonable price.

I am looking for a trinocular headpiece for my Nikon S-kt.

I'm not sure about early signs. If the controls begin to stiffen over time, it could be possible that the fine focus spur gear could be serviced with something that renews the plasticisers. In my case, it was obvious to tell the gear was ruined. The fine focus would catch and run smoothly for most o...

Re: Looking for Nikon S-KT

Thank you for the link Pete, this seems like the most reliable option, but I'll look around a little bit first.

I see it pays to be the only guy in town for the gears. (I'm guessing it's actually quite time-consuming to manufacture these properly).

Re: Looking for Nikon S-KT

The flashlight idea is very clever, and I will definitely consider doing this.

As I expected, upon taking the scope apart in its entirety is that the nylon fine focus gear is hooped. Time to begin the search for a brass spur gear!

Re: Looking for Nikon S-KT

Of course, being new and ignorant I missed that the entire housing for the lightbulb has been seemingly screwed out and removed from the microscope. So I'll have to try and find that part. But perhaps I can get the LED illuminator conversion kit and save the trouble in the first place.
