Re: Source for 1/4 wave filters

Do you need precisely 60mm or at least 60mm? A cheap source would be a 62mm circular polariser with the linear filter removed. I'm out of my league here, filter-wise. I think something between 60 and 55mm would work, but not sure. I'm willing to try of course. I can redesign my rotating slider to a...

Source for 1/4 wave filters

Looking for an inexpensive source for (3) 60mm (actual filter diameter) 1/4 wave filters. I tried some Edmund Optics 1/4 film, but it's a bit too 'thin' for my intended purpose.

Re: short locking tweezers or other small holders / manipulators? Alligator too harsh, fragile subjects for pins

I've never tried what you're asking about, so this may be a moot response. :roll: Perhaps a pulled glass needle or a sharpened 0.25mm tungsten wire would work. A couple of photos of tungsten wire.

Re: Surirella lacrimula

Hi Jim, Great photo , exceptional details ! How do you like this Nikon 40x 0.95 objective ? BR, Saul Thanks Saul. The Nikon 40x 0.95 CFN PlanApo is the best 40x I have, so I can't complain. My DIC system is limited to 20, 40, and 100 objectives. My Nikon PlanApo CFN 60/1.40 performed poorly with th...

Surirella lacrimula

Slowly attempting to get back into Microscopy after a long hiatus. The slide was provided by Bill Dailey. A little larger image is posted here;

Re: Actinoptychus heliopelta(?)

Thanks Rik. Maybe I'm just expecting too much from the Nikon 'phot' DIC models which use a long shear DIC. An Optiphot in my case.

Actinoptychus heliopelta(?)

I've been working on getting my Optiphot Biological up and running again. It's been a while since I've done much imaging. Note the question mark in the subject. :roll: This image stack was done with an old Panasonic GH-3, no relay lens, and projected directly onto the camera sensor.
