Fluorescently labeled C. elegans movie

Description: This movie shows C.elegans moving under white light and then a green filter is inserted and the white light reduced and an ultraviolet light turned on to see the fluorescence of these genetically modified C.elegans with labeled nuclei of the nervous system.

Laser wrinkle removal

Description: using near infrared lasers that pulse quickly, collagen fibers are heated and when they cool the skin surface wrinkles are reduced. The flashes are normally invisible to the naked eye but are made visible because videocameras are sensitive to near infrared light.

laser hair removal

Description: using near infrared lasers that pulse quickly, hair follicles are heated and the hair cell killed. The flash is normally invisible to the naked eye but are made visible because videocameras are sensitive to near infrared light.

RGB color patches

Description: this file has pure red, green, and blue color patches as well as combinations. It can be used for reflectance measurements. Results will vary based on your printer. You can also use them directly from your computer screen to show how each color is composed of varying amounts of red, green and blue light.

eye and face under near infrared light

Description: Here you see the picture of an eye as seen under near infrared light. The brown eye is seen as light in color as it reflects the near infrared (800-1200 nanometers). A blue eye would appear darker as it is more transparent to those wavelengths

Biophotonics and Vision Correction

Description: The eye is made up of different structures that allow it to receive light from the different objects that form our world. Detectors at the back of the eye (retina) sense the light and convert it into an electrical signal which is sent to the brain. The brain interprets the different colors and intensities of lights and puts them together as an image.

Mystery Reflections: Fluorescence and Biophotonics

Description: There are things that you cannot see because your eyes only detect the light that comes from objects in the specific range of colors that are part of visible light. However there are some materials in our world are fluorescent. When you shine a black light upon them then they will glow back a bright color that was not there before.
