Video test for testing an illuminator LED - Luxeon 1W - Nikon microscope adapted to a Fluophot.
I used an image with little motion-rotifer - and other more moving - ciliates -
Have employed different lighting systems, oblique, darkfield .. to determine the characteristics of LED lighting
What do you think?

Nice video, those cilliates behave like microscopic vultures.
The illumination seems to work perfectely, very even.
Because I'm thinking in transform some microscopes to LED illumination, but I'm an absolute ignorant in electronics, can you provide images and details about your setup?

Francisco,

I also would like to see pictures of your LED setup.

Not sure what to think, Francisco. I am pretty sure your low lux CCD camera can handle the LED light OK, although the second half of the movie seemed a little darker than your normal movies do.

It sure will be cooler though, and take a lot less energy to run it.

Francisco,

a very clear Video! By the way: Do you know the species of the ciliates feeding on the dying rotifer?

Thanks guys for your comments.

Mitch: I have no much experience in this LED illuminator, so I have try no "over-bright" this system.

Franz: I think it could be Prorodon ciliate.

LED Illuminator is made of an 1W luxeon white led and a northbridge PC cooler.

I have used an old zeiss illuminator to put this led system inside and be able to center the led inside it.

The cooler is fixed to bulb socket with 2 components Nural (or poxipol).

Dimmer is homemade (DIY) - see schematic.

Best regards,

Francisco.
