LED Illumination For Microscopes.

Use of blue or blue light for bright-field microscopy, without a filter to tone-down the blue-end is potentially hazardous to eyesight. Dark-field microscopy is probably much less hazardous. Dichroic filters are available to remove selected portions of the spectrum, normally expensive, but bargains may be had from eBay. I recommend that anyone considering this should investigate '

To adjust the contrast in a bright light microscope, move the condenser so that it is as close to the stage as possible. Close the aperture all the way. Look through the eyepiece and check the contrast. Slowly open the aperture while continuing to view the specimen through the eyepiece. Stop when the image is bright and clear. If the image appears distorted, you have opened the aperture too

Why Is the Field of View Brighter Under Low Power

Darkfield microscopy is a mode in which direct light is prevented from passing through the objective aperture, but a hollow cone of light forms an apex in the plane of the specimen. The image is formed by light scattering from features of the object. Details appear bright white against a dark background. Darkfield can also be used for living bacteria, algae and plankton.
