Digital Images by David & Stephanie Salter
Toward the end of David's teaching career he had an opportunity to use a Nikon fluorescent research microscope and a dissecting microscope to capture images of both microscopic and macroscopic specimens, respectively. The digital camera used on both scopes was a 3 megapixel Nikon Coolpix camera which was "state of the art" back in the late 1990's. Here is a small collection of biological material that is impossible or difficult to see with the unaided eye.
In fluorescent microscopy, the light comes from the specimen instead of the microscope. The specimen is treated with dyes which attach to specific target material and fluoresce different colors when exposed to UV light generated by the microscope.
