Lasers use a beam of light to engrave or etch information directly on the surface of a variety of materials. … This point when the beam is focused perfectly is called the focal point. The distance from the lens to the focal point is called the focal distance or working distance. ...
CO2 lasers pose slightly less of a problem as long as the standard laser safety systems are in place. Your CO2 laser is built into a metal box with a clear polycarbonate window. The polycarbonate will block the IR laser light when the lid is closed. A safety switch is built into the ...
for tracking and work well on non-glossy surfaces. laser mice use lasers, offering better performance on various surfaces how does an optical mouse work? an optical mouse uses an led to illuminate the surface beneath it. the mouse then captures the reflected light and uses an image sensor to...

Yes, there are specialized scanners called 3D scanners that can capture the shape and dimensions of physical objects. These scanners use lasers or structured light to create a digital representation of the object in 3D format. Can I scan barcodes and quick response (QR) codes using a regular ...
Have you ever tried writing with a beam of light? Sounds impossible, doesn't it, but it's exactly what a laser printer does when it makes a permanent copy of data (information) from your computer on a piece of paper. Thanks to sci-fi and spy movies, we tend to think of lasers as...
Derived from the terms "excited" and "dimers," these types of lasers use reactive gases, such as chlorine and fluorine, mixed with inert gases such as argon, krypton or xenon. When electrically stimulated, a pseudo molecule (dimer) is produced. When lased, the dimer produces light in the...
Some types of holograms use lasers that produce different colors of light as well. Depending on the type of laser you're using, you may also need a shutter to control the exposure. Lenses: Holography is often referred to as "lensless photography," but holography does require lenses. However...
Previews the panel discussion 'Lasers, Pulsed light and Peels, Which One and When,' at the American Society of Plastic Surgeons' Meeting in October 2003 in San Diego, California. Need for the surg...
How can you measure the speed of light with a laser? How does a Raman laser work? How much nitrogen does a fiber laser use? How is an excimer laser produced? How do tunable lasers work? How is tunability of wavelength achieved in a dye laser?
