As in the title whats the most cost effective (read cheapest) microscope capable of finding nosema. i have been looking on e-bay and it is a bit bewildering. Links to anything that fits the bill would be good.
Many thanks.

Hi VEG,

My apologies for not getting back to you sooner, but we have just had one of our dogs die and have gone a bought a puppy.

Right Microscopy.

When using a microscope at our level the term is ?Light Microscopy? as we only magnify to a maximum of about X1600. Anything above that and its electron microscopy.

So what as beekeepers do we use microscopes for?

To test for bee diseases,
(A) AFB ? EFB Yes X1000
(A) Nosema Yes X400
(B) Acarine Yes X20-50
(A) Malpighaimoeba Yes X400
(C) Viruses No X1000>

(A) Pollen Yes X400>

(B) Internal organs yes X20-40 (X100>)
(B) External organs yes X20-40 (X100>)

Types of microscopes.

For small magnification we use a Stereo microscope which is used for dissection work. Ideally it should have a magnification capability of X5 ? X30 with eyepieces of X5 or X10. Lighting is from above and (below but this is not essential). A good working distance from the objective to the base is needed as one will be handling instruments.
Stereo microscopes will give a good 3D image of the object.
Uses; (B).

For all other uses a Compound microscope is required. With this type of microscope it must have 4 objectives X4 X10 X40 X100, with eyepieces of X10 or X12.5 or X15.
The stage should be a mechanical stage with graticules running on the ?X? and ?Y? lines. The remainder of a compound microscope comes as standard and there are accessories that can be purchased for various other manipulations.

I have not mentioned price as you get what you pay for.

So VEG you wanted to test for Nosema so you would require a compound microscope.

I have seen other children?s ocular microscope that can magnify to about X500 and can be fitted to a PC or Laptop. I do not know what they are like for resolution etc.

Hope this helps.

Regards;

two types of microscopes

The first microscope is my compound which is a trinocular (three seeing tubes).




this one is a typical dissecting microscope.



Any questions feel free to ask away.
