This model microscope does not win many points on ergonomics; not with the focus knob at the back. The reason for placing it there, is that the mechanism that raises and lowers the objectives is rather chunky. By turning the focus knob, a linear actuator lifts or lowers the objective carousel. Of course, it is possible to raise them too high and crush the objective into the table. If you have never cracked a slide, you never have used a microscope! (After I wired the microscope up, though, the carousel gets stuck just below the maximum height...)

Objectives with magnification ratings and stage graduations of a compound light microscope. Equipment useful in research as well as teaching purposes.

Slide #14. 10x Magnification. Spleen. Dense connective tissue. (Connective tissue capsule with trabeculae).

Camera

Immediately above the oculars is a shutter, that in one position directs the light beam through the oculars, or in the other position, directs it to the camera mounted on top. As with the camera on top of it, it doesn't really work.

A small £3 attachment from Tiger has allowed me to turn my phone into a microscope.

HD Video, 1920x1080 pixels

10x Objective

0.17 N.A.

2 pixels per micron

Resolution limit should be 1.97 microns.

At 3.5 pixels per detail, with the 1.6 Canon sensor I _think_ this means we are using 1,610 pixels of the 1920 pixels of the width of the frame.

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.

The Institute of Making and the London Centre for Nanotechnology have teamed up with Tsinghua University and Peking University to take on the challenge of developing a new type of low-cost scanning probe microscope with the power to capture images of the nano world.

LEGO2NANO is an international student project making real science accessible to young people, by developing low cost scientific equipment for schools and beyond.

Over the last three years of the summer school in Beijing, international and interdisciplinary teams of university students have developed their Open AFM—an open-source atomic force microscope assembled from cheap, off-the-shelf electronic components, Arduino, Lego and 3D printable /laser cut parts.

Got a real microscope! This thing is nice!
