This microscope illuminates samples from above as well as from below as in a conventional microscope. Most users will be interested in using light from above the sample to illuminate and energize the sample. Excitation in the ultraviolet (330-385nm), blue (460-490 nm), green (510-550 nm) and full spectrum light are available. The microscope has magnifications of 20, 40, 100 and 200 power. Both the reflected light and sample fluorescence may be viewed through and recorded at the microscope. A Nikon Coolpix 5.1 megapixal camera as well as a USB camera with image capture software are available for recording images.
