Trekker
Palm Microscope
Ref no: 162
Price:
£49.95
Description: This is a portable, inexpensive, high quality microscope with precision optics.
It's perfect for field, classroom and laboratory study.
The Trekker is easy to use too. Just place your specimen on the top of the microscope and focus using the thumbwheel underneath. The special magnetic holder can also be used to hold the specimen if you wish.
The 35x magnification – chosen on the recommendation of teachers and professional field workers – is powerful enough to provide great detail but provides images that are not so greatly magnified that the sense of what you are viewing is lost.
Trekker’s ultra compact shape is achieved by the use of folded optics which compress the normal 150mm tube length of a conventional microscope by the use of precision mirrors.

The
photos above give you a better idea of how the unit looks.
The picture on the left shows the microscope out of the box. Basically you
place whatever you want to look at on the lens on the top, and then look
through the eyepiece on the side. That rubber eyepiece can be turned around
to suit either eye, and you can even remove to use it as a 10x hand lens.
The photo in the centre shows the base of the Trekker. There's a tripod bush
in the middle, the battery compartment is just below that, and the focus
thumbwheel is top left.
The shot on the right shows what you get in your box. The microscope
(obviously) plus a cloth carry case, a 9V battery, two glass slides (one
plain, one prepared), a magnetic slide holder and some instructions.

You
can buy an adaptor to attach the Trekker to a digital SLR, but for the
purposes of testing it out we simply pressed a cheap compact digital camera
directly next to the eyepiece. The results were surprisingly good. We found a tiny
dead insect on
a window ledge. You can see how big it was by the size of the match head
next to it. Under normal daylight we got this photo of the head. We had to
shrink the photo down for the web page, but you get the idea.
 You can clearly see the compound structure
of the eye and even the ocelli - miniature eyes on top of the head capable of sensing
light.
