(L:) Digital microscope

A digital microscope is a variation of a traditional optical microscope that uses optics and a digital camera to output an image to a monitor, sometimes by means of software running on a computer. A digital microscope often has its own in-built LED light source, and differs from an optical microscope in that there is no provision to observe the sample directly through an eyepiece. Since the image is focused on the digital circuit, the entire system is designed for the monitor image. The optics for the human eye are omitted.

*** subjects

* dermatology (pest)
    nits 800x300 micron
    mites ~500 micron

    * http://ojcpcd.com/cohen-yoon/dermatoscopic-diagnosis-of-scabies/

* pests/biology ID

* water (and contaminants?)
    amoeba ~10-2000 micron

* microbiology / medicine
    white blood cells: >10 micron 

* hair
    10~200 micron, typical ~50micron

* bacteria ... like conjunctivitis
    """Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae"""
    …and the spherical cells of Staphylococcus aureus are up to 1 μm in diameter

* Wolbachia:

Wolbachia is a genus of intracellular bacteria that infects mainly arthropod species, including a high proportion of insects, and also some nematodes.[1][2] It is one of the most common parasitic microbes, and is possibly the most common reproductive parasite in the biosphere.[3] Its interactions with its hosts are often complex, and in some cases have evolved to be mutualistic rather than parasitic. Some host species cannot reproduce, or even survive, without Wolbachia colonisation. One study concluded that more than 16% of neotropical insect species carry bacteria of this genus,[4] and as many as 25 to 70% of all insect species are estimated to be potential hosts.[5

* agriculture

seed ID?
pest ID?

The most basic microscope you need to work with on the farm needs a magnification of 10x, 20x and 40x. If you have more money to spend it is ideal to get magnification of 4x and 100x oil. You need an adjustable light source and stage (platform) and preferably 10x eyepieces. You’re well advised to go to one of the many microscope courses on offer.

[!!!**] STUFF— Found microscope in Madrid (LEICA/WILD M3Z)


Hair are pretty big at 30x.
So I'd say you can kind of looks at things ~10 micron (0.01mm).

————————— info

Zoom Range 6.5-40x

This Leica/Wild M3Z Stereo Microscope has been serviced by a qualified microscope tech and meets factory specs. It has its Wild 10X, high eyepoint widefield eyepieces and a 1.0X bottom objective. In my opinion, the M-Series by Leica is the best stereomicroscope available. I like Zeiss as well, but have never had a Leica optical element delaminate. The M-Series is the microscope you want if you spend a lot of time looking through the eyepieces, want the brightest, flattest field and highest resolution. Built for demanding users, the Wild/Leica M-series is built to last.
Your Price: $2,200.00

[!!!] get the exact instructions/specs

The stereo microscope is often used to study the surfaces of solid specimens or to carry out close work such as dissection, microsurgery, watch-making, circuit board manufacture or inspection, and fracture surfaces as in fractography and forensic engineering.

Spider silk

Atomic force microscopy (AFM) revealed that both the spider dragline and silkworm silk consist of bundles of twisted nanofibrils (30–35 nm in diameter).
