Microscopes
are now using LED Lighting
LED lighting on traditional microscopes has a
number of advantages. In general LEDs outlast tungsten globes. The effect of
tungsten filament heating is not a design issue with LEDs. LEDs are powered
from low voltage DC sources so do not require the same power output. As they
can be powered by battery microscopes using LEDs can be used as a field
instrument. An example of a dual LED light source monocular microscope is shown
below.
“Those
microscopes are still going strong, the best investment in microscopes we have
made. They are so versatile!
We have
a young casual Science teacher at the moment who is here on a visa from UK .
Her husband is doing research at Newcastle
Uni and she has just completed her Masters in Biological Sciences …...
Yesterday she wanted to take a class outside and to look at organisms under a
microscope – she came into my prep room lamenting that she couldn't take
microscopes with her –
I demonstrated these microscopes, and she was ecstatic!
She had a great class outside, and the students enjoyed doing it.”
