Universe Optics offers lens design and optical lenses for industrial, medical, high tech and electronic applications. Specific wavelengths within the spectrum correspond to a specific color based upon how. Visible light - that which is detectable by the human eye - consists of wavelengths ranging from approximately 780 nanometer (7.80 x 10 -7 m) down to 390 nanometer (3.90 x 10 -7 m). Gamma rays are used in medical practices and assist in treating cancer by shrinking tumors through the use of radiation therapy. This narrow band of frequencies is referred to as the visible light spectrum. Gamma rays come from subatomic particle interactions such as nuclear fission and nuclear fusion. Gamma rays: A gamma ray emits high energy and are the most dangerous of the wavelengths on living organisms.A microwave can harm the body because it can heat the water molecules in deep tissues. Microwaves excite the water molecules in food, heat them up, and pass the heat throughout the food. As students explore the physics of light, they are introduced to the electromagnetic spectrum and the portion that constitutes visible light. When teaching about visible light, students learn that light is a form of energy and travels in waves (similar to sound). Microwaves: The wavelengths of microwave fall between radio and infrared waves on the electromagnetic spectrum. Teaching About Visible Light and the Physics of Light in K-12.Human tissue, bone and cartilage absorb most of the x-ray wavelengths. The wavelengths penetrate the skin and form a radiographic image. X-Rays: This light wavelength commonly used in medicine.Radio waves are used for communicating through the modification and amplification of sound waves. Radio waves: These light waves have the longest wavelength of all invisible light.There is a near infrared light and a near visible red light, and far infrared light. Our eyes perceive different wavelengths of. Light waves have wavelengths between about 400 and 700 nanometers (4,000 to 7,000 angstroms). Infrared light: This light lies past the red end of the visible light spectrum and falls between visible light and microwave wavelengths. Visible light is just one of many types of EM radiation, and occupies a very small range of the overall electromagnetic spectrum but because we can see light with our eyes, it has special significance to us. Most of this light reflects off the ozone layer but the rays that penetrate can cause sunburn on unprotected skin. Ultraviolet light: This light is past the violet light electromagnetic spectrum.There are vast amounts of the electromagnetic spectrum that are invisible to the naked eye, but even though they’re unable to be seen, they can still be potentially dangerous. Visible light wavelengths run from 400 nanometers for violet light to 700 nanometers which is represented by red light. Many color waves, however, are invisible to the human eye. All colors of light are made up of electromagnetic radiation and it travels in waves, some of which are visible to the human eye. Standard and custom hi-res lens assemblies.Ī rainbow is a representation of the electromagnetic spectrum. What Is Non-Visible Light? High Resolution Lenses for machine vision, instrumentation, inspection and vibration-sensitive applications. Sources of x-rays include million-degree gas, exploded stars, and material colliding around black holes.High resolution lenses for machine vision - standard and custom lens design The blue color shows Chandra's view in x-ray light. Most of this light comes from stars, and they trace the same spiral structure as the dust lanes. The spectrum is arranged in the order red, orange, yellow, green, blue, indigo, and violet according to the different wavelengths1 of light the light in the. The yellow color is Hubble's view in visible light. It highlights the heat emitted by dust lanes in the galaxy where stars can form. The red color shows Spitzer's view in infrared light. This composite image of the spiral galaxy Messier 101 combines views from Spitzer, Hubble, and Chandra space telescopes. The visible part of the spectrum may be subdivided according to color, with red at the long wavelength end and violet at the short wavelength end, as.

Martian Soil - This false-color infrared image from the Thermal Emission Imaging System (THEMIS) camera onboard the Mars Odyssey spacecraft reveals the differences in the mineralogy, chemical composition, and structure of the Martian surface.
