Resolution Application Note
Morning Folks, Just read this discussion page from Edmunds Optics. While the math is beyond my limited and diminishing skillset the written explanations were illuminating and improved my understanding of resolution variables in micro/macro photography. https://www.edmundoptics.com/knowledge-center/a...

SOM continued
Folks, Thank you very much for your kind words for my DIY macro/micro rig. (Now called SOM, Son Of Multiphot. I needed a name for my rig after Chris shared his "Bratcam". In deference to his inspiring rig I had no choice to follow his lead.). While building SOM I maintained a photo journal of my pro...

My industrial DIY macro rig
Being of the mechanically challenged and mathematically deficient persuasion I turned to eBay's industrial equipment listings to build my DIY rig. The goals of the stepping component of my rig are: 1. Capable of mounting for stepping different cameras/assorted bellows and tubes using a wide range of...

The cabinet in the center of the photo, also Maple, was mounted on four 4" 360 degree rotating non-skid casters. The table, on the right side of the photo, has a 2 1/...

I take no credit for any feature or design used in my DIY stand. I only take credit for copying and/or borrowin...

Formula for f number
Rik, I very much appreciate your quick response and understandable explanations. I have written your formulas into my studio journal for future use. Your ability to explain how your formulas can be used while at the same time showing how they are related to the physics of optics and light is most, h...

Hi Rik, Back in my earlier days of photomicrography when I was suffering from NAS, (in remission now), I acquired a Nikon Ultra Micro Nikkor 30mm, effective aperture, according to Nikon, of f/1.2, and magnification 1/25X. Now that I have my DIY macro rig up and running I plan on reversing the lens a...

diascopic illuminator with specimen stage
Hi Mike, Depending on how you intend to use your Multiphot stand the diascopic illuminator and specimen stage may or may not meet your needs.

Zeiss AC, Zeiss Axiomat
Hi Eddie, Given your email name of Axiomat123 just wondering if you are using a Axiomat and if so how the AC will complement your Axiomat? Don't see the name of Zeiss's Axiomat microscope to often so I am curious. I have two Axiomats, plus far to many surplus Axiomat parts. Again wondering what you ...
