Video 2: Imaging Capability: Brightfield imaging with transmitted or Reflected Light

Video 3. Using 16MP to show transmitted brightfield sample images of BMU500

This video demonstrates the microscopy camera BRC-1600 which is a 16MP 1/2.33″ USB 3.0 colorful camera. The camera is connected to one of our upright industrial /metallurgical microscope BMU500DIC with 0.37x c-mount adapter, Windows 10, and sample images of Tilia (Basswood) are shown at different objective lenses.

Video 4. Fluorescence Imaging

This video demonstrates Bioimager BUM360FLED-A LED Fluorescence attachment to use with a standard upright microscope such as BMU500A.. It comes with 5W LED of Violet (V), Ultraviolet (UV), Blue (B) and Green (G) LEDs, and its correspondent excitation and emission filters. The video demonstrates the optics and mechanics as well as sample images at different magnifications.
