Boundary Bay North, 4x/0.16, FLUO-C6, HF A+C

Taken with a Microscope and attached DSLR camera... I made them into HDR's but otherwise did not feel like editing them. Sorry.

This microscope illuminates from above instead of below, which offers a big advantage: the objects being studied don’t have to be prepared in ultra-thin slices. Kids can simply aim the incident light microscope at anything that catches their fancy—articles of clothing, toys, plants, even their own skin. The 50x enlargement delivered thereby provides astounding new impressions and insights.

This group’s quest landed them at the electron microscopy lab, where a researcher showed students how to use a scanning electron microscope. FWRI harmful algal bloom researchers use these powerful microscopes to magnify tiny marine organisms up to 50,000 times.

Nikon microscope with 3 objective lenses. Dutch angle, (sorta).

Messing around with polarizers :P i like how this one came out.

PSA: In Bizarro microscope world, color toner is made out of jellybeans.

These are CSI styled diatoms, dead for about 40 years. Magnification was about 1000 times, I used a Olympus BH microscope for this picture. But I forgot to set the aperture on the microscope right, so that is why it has these ugly corners :P

Getting stuff together to ship to the little one in ABQ before Christmas. I never was very good at just buying 'toys'. Figure I'll let my daughter come up with something for #19 if she asks.

30 seconds exposure time to visualize the amoeba's movement.

Taken in polarized light with phase contrast. Size of the amoeba is about 70 micrometers.

An interesting look at everyday things.

I bought a cheap USB powered Microscope and then started exploring. Some of the images were very unexpected so I thought I would post a few.

(supposedly) melanin pigments under the microscope.

This is what I use when I do some of my engraving, it comes in really handy with detailed crests on signet rings. The scope is at working distance as you see it here, so there is a lot of room to work.

Incredible gift from Pooja's grandfather . . . his company, Labomed, manufactures and sells microscopes for academic and medical professionals.

Vintage microscope, SFO museum, 2012

Before having an aquarium, I used to collect pond water as a kid and would have all sorts of monstrosities (including leeches) in muddy water.

For the germ-paranoid: No, this is not water directly from the tap. I think this might be 50x magnification.

High Quality Professional Compound Binocular Microscope!

Do you know what I'm looking through my microscope?.... Guess....(Polito)

The microscope basically consists of a CD-ROM pickup unit. It contains an infrared laser diode, some optical components, a movable lens and a photodiode array. The laser diode is driven by an LM317 in current control mode. A single photodiode is connected to an amplifier. The current sensing resistor is a trim potentiometer to adjust the sensitivity.

Forus and tracking coils (which move the lens) are driven by NPN transistors attached to the output of a DAC with a carefully chosen base resistor inbetween.

The whole pickup unit is glued to a CD-ROM BLDC spindle motor with the lens facing down. A spring keeps it in position. Current flowing through a single motor phase creates a small amount of movement in the direction perpendicular to the tracking movement of the lens. The movement is rotational and not linear. That creates some distortion in the resulting pictures.

The motor is also driven by a DAC and NPN transistor combination.

A microcontroller communicates with the DACs and slowly moves the lens across the object. After every small movement the photodiode response is sampled by an ADC and the value used as brightness value for a single pixel of the final picture.

Aspect ratio is just roughly adjusted. Several kinds of distortion can be seen in the resulting pictures, resulting from non-linear movement, friction, mechanical shaking and so on.

The aluminum tray is handy to get the target object into position. It is attached to the tray by adhesive tape. The tray also keeps metal objects away from the pickup unit. The focus and tracking coils inside need permanent magnets, making the thing magnetic.

The black tape next to the spring keeps outside light away from the photodiode array.
