Playing with matches and antique microscopes. Leitz objective from 1870. Time is defined by what can’t be undone.
Bit more antique microscope macro, starting to get the hang of it. Bit dry and cold here at the moment, so there’s a shortage of available subjects. Looking forward to the Christmas Beetles at Christmas.
I borrowed a digital microscope from work over the holidays. It's normally used for checking the alignment of digital printers, but allowed some unusual perspectives of other things too.
I began snapping some pictures of a plasma ball that I picked up for Halloween. These things are mesmerizing. And in a photo, they look rather viral.

You can turn the objective lens, and twist both knobs. Check out the videos for the functions!

New addition to my ODD lenses. Now I will use these microscopic objectives with my Nikon camera. Eager to see the results.

Here is another scene from my recent photoshoot in the BYU cleanroom laboratory. This is Zach Walker using one of the microscopes to look at his lithography result on a silicon wafer. The picture has a yellow hue to it because it was taken in a room with yellow lights, allowing for photolithography which is sensitive to UV and blue wavelengths.

Another view of a vintage Spencer Buffalo Stereo microscope, circa 1932. I think this may be a model 55. Spencer is believed to be the earliest successful American microscope manufacturer.

On this exciting edition of From The Archives: A LEGO Microscope.
This build was originally inspired by the LEGO X-Pod sets. While trying to find a use for the pod itself, I realized that it was very close to a deep petri dish. I used a planetary gear system to allow both coarse and fine adjustment of the objective “lens”. A little more tinkering and I connected the focus to a magnifying glass and fiber optic light in the eyepiece, so adjusting the focus knobs would actually bring the writing on a LEGO stud in and out of focus.

After 25 years I have finally replaced my old Stereo and Compound Microscopes. My old microscopes were of good quality and they had served me well over the years, but I have long missed the research grade microscopes that I had used while working for the Federal Agencies. It was time for an upgrade.
The one of the right is a 3.5x-180x Simul-Focal Trinocular Stereo Microscope and the one of the left is a 40x-2000x Quintuple Brightfield Phase Contrast Plan Infinity Compound Microscope.
Both have advanced LED Fiber Optic lighting systems. I also upgraded to a 18MP Microscope Digital Camera that can be used on both scopes (it is on the Stereo Microscope in the Photo).
I have been checking them out in detail over the past week. So far they have preformed as I had hoped. I am more than pleased with my new toys.
An old children's microscope from Tasco, It dates from the late 1960s. Despite being aimed at children it works quite well and is well over 50 years old.
I love to try some different budget microscope lenses. Some of them are great performers like Lomo (3.5X, 3.7X, 4.7X) and Nikon 10X 0.25

A microscope (from the Ancient Greek: μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope.
There are many types of microscopes, the most common and first to be invented is the optical microscope which uses light to image the sample. Other major types of microscopes are the electron microscope (both the transmission electron microscope and the scanning electron microscope) and the various types of scanning probe microscope.
The first microscope to be developed was the optical microscope, although the original inventor is not easy to identify. An early microscope was made in 1590 in Middelburg, Netherlands.Two eyeglass makers are variously given credit: Hans Lippershey (who developed an early telescope) and Zacharias Janssen. Giovanni Faber coined the name microscope for Galileo Galilei's compound microscope in 1625 (Galileo had called it the "occhiolino" or "little eye").

Hi Greyframe!
As you asked - that’s my microscopic equipment. I use an vintage (from the 70ies) Zeiss (West) Standard RA which is equipped for DIC (differential interference contrast), phase contrast, polarization and for good, old, bright field. For DIC I use planachromatic objectives and for bright field I use planapochromatic ones, if possible.
It’s old stuff but these gadgets are very robust and they are still working perfectly well. Moreover, their level of optical performance is not so far away from contemporary benchmarks. Many of these old microscopes are still in use in research facilities all over the world.
My camera is a Canon EOS 70D and I combine it with an old Leitz Elmarit-R 35mm. Microphotography easily pushs optics to it's limits and an Elmarit simply yields a slightly better resolution than Canon lenses. The difference is not big, but you can spot it nevertheless. For microscopic sessions I use live-remote-control-mode, that’s much more comfortable than anything else.
Zeiss ceased production of these microscopes at the end of the 80ies or so, so their original camera-adapters don’t fit to digital DSLRs. Fortunately I found someone who was able to build me a fitting adapter. Quite the same is true for the lamp - I use a LED instead of the original light bulb and this contraption was built and adapted by another microscopy buff.
Ah, and I use a software called Zerene for stacking. It’s output still needs some adjustment of contrast and brightness and some cleaning up, too. Nevertheless, if you don’t have microscopic pictures of high quality and high resolution as an input you cannot end up with a good picture in the end. Photoshop cannot compensate for bad resolution and so on.
OK, I don’t know whether all your questions are answered by now - if not, just ask. Maybe, my answers will come with some delay but there will be answers :-)
This creation uses 4 LEGO magnifying glasses to create a fully functional compound microscope. Other features include separate coarse and fine adjustment knobs, power functions LEDs and a rotating stage.

Custom logo print by Dan Kees:
Microscope lens setup. Effectively extension tubes and a extension tube to RMS cone adapter giving approx 160mm from focal plane to objective. A USB mini LED lamp fed from a rechargeable battery block (that goes in my pocket). The disc near then of the cone is actually a twin flash mount.
Parts. Sony A6000, Sony to EOS lens adapter, EOS to M42 adapter, M42 extension tubes, M42 to RMS cone, 4X 160mm microscope lens.
I already had these but obviously the adapters depend on the camera body in use but you need to get to M42 for the RMS adapter. The most common RMS adapter is a flat disc, if you use this you will need to use more M42 extension tubes.
This is a partially disassembled microscope made by E.F. & F.H. Tighe, Detroit, Michigan, possibly their No. 5 version, ca 1889.
It had been dropped while in its box from a height of about three feet thoroughly jamming the focusing mechanism. A friend wanted to know if it could be repaired since it has great sentimental value. The focusing mechanism was jammed to the point where it was locked, producing no tube movement, but a definite "skip" as the pinion gear engaged the rack. Fortunately, the rack is actually made from a slightly bowed thin piece of brass... not a thick solid piece. Anchored with screws at either end, the rack has a bit of springy flex to it, preventing gear or rack damage when forced. Getting the tube off the focusing assembly without damaging either was accomplished by directing a thin stream of hot air onto the focusing block, then precisely applying WD-40 with a blunted toothpick. Once the tube was removed, small bits of brass were cleared away and the slides cleaned and polished. De-gunking the surfaces of the slides was difficult because they had a thin coating of hardened black grease that would not move using any kind of cleaner. Cotton swabs dipped in boiling water finally softened the stuff to the point where "Nevr-Dull" brass cleaning wool was able to do the job. Reassembled, the scope is now back in its original configuration and looks great. Some folks have been known to clean off any protective lacquer and polish the brass to a mirror finish. That would be OK if this was still in the maker's display case waiting to be sold, but would totally destroy the nice patina that 130 years of aging has produced.
