Re: WTB: coaxial illuminatot for Wild M420

PM Sent, this unit I found has slight de lamination on one side of glass (you can see the round spot in photo), I have others probably in better condition. I can send you higher res photos to your email.

WTB Aus Jenalumar Condenser Rack & 40x

Hi I'd like to buy the condenser carrier including gear rack (strip of teeth) for a Jenalumar. I really just need the gear rack I have the pinion and knob assembly.

I am also looking for a 40x or 50x objective preferably with DIC prism installed.

Re: Repairing an Olympus 40x Apochromat

I also have a 40x Splan APO with terrible performance, non flat image, hazy and awful spherical abberation. It looks ok through back element, but its not useable on the scope. Also thinking about some kind of disassembly and fix, however improbable.

Re: Pollen. There's lots of it about.

As an allergy sufferer this is thread is making me sneeze! Here is a SEM image I took of purple hibiscus pollen from the backyard. Not sure if the surface is flaky like that or if its the gold layer added (approx 153 angstrom thick) necessary to image in sem.
