Microscope illuminator
(click to
enlarge)
To get the microscope images I've build an illuminator to put above the
glass.
It's good for darkview
images; the light spectrum of LEDs
is made of narrow bands and you can get better images than with
the bulb that emits a great amount of infrared light.
It wont win a beauty award but it works greatly :-)
It's made of a 220 ohm resistance, a 1N4148 diode and three white LEDs;
it is powered at 8-13 volts.
The LEDs are mounted in a 1.5cm high, 3cm wide white plastic tube and
are
fixed to the centre/down direction; in the opposite side of LEDs it's
glued a strip of lead.

Robust, light and economic :-)
The appearance can be debate but
it
has a theoretical resolution of 2 micron/pixel (150x), it gets the
focus
till 5cm on water and resolve about 10 micron (30x).
The optics come from an old video camera, the body is composed of two pierced
plastic stoppers glued one on the
top of the other, in the bottom one I carved and folded
thermally the three teeth for the rotation hook.
It permits to use contemporary
the optical/digital camera zoom; It's the bracket for the microscope
adapter too.
ATTENTION just before the camera
optical zoom closes it goes out 2mm more; you must take it in account,
the adapter must not hinder the
optical zoom.

A simple adapter easy to build, it's composed of a pierced plastic
stopper and the top of a plastic water bottle glued inside.
This adapter will be inserted in the zoom adapter without the optics
to be coupled to the camera.
