Uses of spectrophotometer? Spectrophotometry involves the use of a spectrophotometer. A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color, or more specifically, the wavelength of light. There are many kinds of spectrophotometers.

Laser A laser consists of a gain medium, a mechanism to energize it, and something to provide optical feedback. The gain medium is a material with properties that allow it to amplify light by way of stimulated emission. Light of a specific wavelength that passes through the gain medium is amplified (increases in power).

Laser Divergence Optotronics handheld laser products have a divergence spec. of 1.2mrad orless (unless otherwise noted). Most other suppliers of handheld laser products have a divergence spec. of 1.5mrad. This means that for the same beam diameter and output power, the light intensity or irradiance (Output power / area of beam spot) is up to 56% greater with a divergence of 1.2mrad vs 1.5mrad.

Optical power meter Optical power meter. An optical power meter (OPM) is a device used measure to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Other general purpose light power measuring devices are usually called radiometers, photometers, laser power meters (can be photodiode sensors or thermopile laser sensors), light meters or lux meters.

A Skeptical Look at Low Level Laser Therapy Low-level laser therapy (LLLT) refers to the use of a red-beam or near-infrared laser with a wave-length between 600 and 1000 nanometers and power from 5 to 500 milliwatts. Low-level lasers do not produce heat. In contrast, lasers used in surgery typically use 300 watts and burn the tissues they encounter.

How Do Laser Thermometers Work? Laser thermometers are actually infrared thermometers. The laser is just there to make the thermometer easier to aim. Molecules are vibrating constantly; the hotter the molecule is, the faster it vibrates, creating infrared energy. Infrared (IR) thermometers measure the infrared energy given off by all objects.

What is a laser? The wavelength of high energy light emitted by the laser is converted to heat energy and this damages the specific target area. Thus alexandrite lasers work by a process of photothermolysis: this means using light (photo) to heat (thermo) a selected area for destruction (lysis).

What is MicroPulse? MicroPulse Laser Therapy. MicroPulse laser therapy is a retina sparing solution for the treatment of Diabetic Macular Edema (DME). With MicroPulse, the continuous-wave laser beam is chopped into a train of tiny, repetitive, low energy pulses separated by a brief rest period in between. This allows the retina to cool between laser pulses. During MicroPulse laser therapy, your doctor places laser pulses in the areas of DME. The main goal of treatment is to prevent further loss of vision, but improvement in vision is possible.

Rulers of Light: Using Lasers to Measure Distance and Time In another experiment, he measured the frequency of an optical transition in cesium atoms (a change in their state that absorbs or emits light at a precise frequency) using a mode-locked laser to span the difference in frequency between two CW lasers. His results inspired a group of us to undertake serious research in this arena.
