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

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.

These microscopes have a very long focal range and a thus accept a wide range of objectives. The fine focus limits DoF to about 5mm for stacking.

Video of a feedback loop caused by filming the pixels of a video feed (of the pixels of the same video feed) using a USB microscope.
wide assortment of superior quality Digital Microscopes that are highly result oriented. Our digital microscopes are appreciated for its high-end performance and reliability, durability and easy maintenance. All the microscopes manufactured by us are available with custom modification depending on the parameters set by the clients.
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.

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.
I’m biology class student. I belong to the molecular biology lab.
Sometimes, I use microscope because i see the bacteria. But most microscope is breakdown. Outside that, Natural sciences building is shabby. So building image is gloomy. We want his(HANSEO　PRESIDENT) care! Please... I hope our building like a your building!
User interface for my Nikon converted microscope. I mounted a stepper motor on the nikon stand. With microscope lenses I can use stacking photography again. I have a generic lens 4X, 40x and 100x that can give me beautiful images via the Nikon D7100. The step size for the 4x lens lens is 20 um. For a height of 2mm you have to take 100 pictures. With the Zerene stacking software, a photo is then compiled. This software can also create a 3D image. Later I will post more information about the device.
The main controller is the Fischertechnik TXT Controller and connected via the I2C to mijn FPGA unit.
Just taking a much closer look under our microscope. We did a lot of microsurgery trying to fix the thing.
This is a Victorian era student microscope which used to belong to my grandfather, who purchased it second-hand many years ago. It was created by Broadhurst, Clarkson & Company, who were resident at 63 Farringdon Road in London during the mid to late 1800s and were manufacturers of fine quality instruments to the gentry and scientific community.
The body of the microscope is made from brass; it's a lovely old thing and a lot of fun to use...especially because its box was packed with a range of vintage slides from the early 1900s. These beautiful objects have now been superceded by modern technology, but they remain very usable instruments which symbolise an exciting and important time for science.
Microscope slides in a brown box made of thick paper material with small metal pieces on each edge around the four sides. One edge is splitting, and some others are bending and folding inward. Centered on the top is a logo. There is a wide diamond symbol with "Diamond Brand Slides Covers" around the edges and "JMF" in cursive script at the center. Inside are many glass slides as well as a piece of paper at the bottom that says, "Non-Corroseive Micro Slides / Made in U.S.A."
