We look forward to inquires as opportunities to provide better services. The laser parts in this catalog are sold as components only. Unless the item is labeled as C.D.R.H. certified, the item is sold as a component only. For information about C.D.R.H. regulations see the section with the same heading on page 18. Brief Laser Glossary Class The Center for Devices and Radiological Health classifies lasers by maximum output power and wavelength. The lasers in this catalog are class II, IIIa, IIIb, and class IV. The higher the class, the higher the maximum power, and correspondingly, there are more safety precautions that must be maintained. Divergence The full angle at which a laser beam expands. Expressed in milliradians (mRad.), it corresponds to approximately the number of millimeters the beam will spread for each meter of travel. For example, a 1.5 mRad. divergence will correspond to 15 millimeters of beam spread at a 10 meter distance. 1.0 Relative Sensitivity Apparent Power / Brightness The intensity of light as it appears to the human eye. The eye is most sensitive to wavelengths (colors) in the center of the visible spectrum. Hence, green light will appear brighter tthan any other color of light of the same power or magnitude. As another example, a 633nm red Helium-Neon laser appears approximately eight times brighter than a red 670nm diode laser of the same output power. See the diagram to the right for relative eye sensitivity versus wavelength. 0.1 0.01 0.001 0.0001 400 500 600 Wavelength (nm) 700 Milliwatt The power that gives rise to the production of energy at the rate of one one-thousandth of a joule per second. In less technical terms, it is simply the amount of light energy. Mode Only the single spatial mode, TEM00, provides a solid beam throughout its diameter. Multi-mode lasers have an increased overall power output for the same size tube, however, the wavefront intensity is segmented. Wavelength Electromagnetic energy is transmitted in the form of a sinusoidal wave. The wavelength is the physical distance covered by one cycle of this wave. Visible light is in the electomagnetic spectrum from 400 nm to 750nm. Within this range we percieve the light as being different colors. At 400nm light is a deep violet color, at 500nm- green, 590nm- orange, 700nm deep red. Polarization With respect to a beam of electromagnetic radiation, the polarization direction is the direction of the electric field vector. The polarization vector is always at right angles to the beam direction, and can be random (unpolarized beam), linear, or elliptical. C.D.R.H. Precautions The lasers listed in this catalog are classified as class II, IIIa, IIIb, and class IV. Depending on the type and power, all lasers should be labeled with one of the following warning logos: CAUTION LASER RADIATION- DO NOT STARE INTO BEAM OR VIEW DIRECTLY WITH OPTICAL INSTRUMENTS DIODE LASER Wavelength: 630 - 675nm CLASS II LASER PRODUCT DANGER LASER RADIATION-AVOID DIRECT EXPOSURE TO BEAM DIODE LASER Wavelength: 530-675nm Max.

Item #: HOLOMB Only $16.95 Laser Lightshow Glossary Beam Effect Using the lasers beam as a sculptural element in space (as opposed to shining it on a wall to create graphics) . A common technique is to scan the beam through theatrical smoke. If a line is scanned you will see a plane of laser light; if a circle is scanned you see a cone. Lumia A gauze-like effect produced by shining a laser beam through distorting material such as rippled glass. Scanner Any device which moves back and forth; usually refers to a galvanometer scanner. Two are needed to draw laser graphics. A mirror on each scanner moves in response to an electrical current. The scanners are arranged so the beam reflects first off one mirror, then off the other. The first mirror moves the beam horizontally, the second moves it vertically. This arrangement means the scanners can position the beam anywhere within a square area. By repeatedly scanning the same signal at high speeds, the illusion of a single, fixed image is created. Scanner Amp An electronic device which conditions a signal from a computer or other source, and makes it compatible with galvanometer scanners. Closed-loop scanner amplifiers are used with position-detecting scanners; the amplifier controls the scanner based on position feedback signals. Open-loop scanner amplifiers are used with non-position detecting scanners. Laser Projector Equipment which takes a laser beam and produces projected graphics or beam effects. Vector Graphics Images created by moving from point to point examples include handwriting and computer plotters. Most laser graphics are vector graphics. To produce a laser graphic, a computer is first used to draw a series of connect-the-dot points. These are translated to electrical signals and are sent to the scanners. At the projection screen, the moving beam travels from point to point at high speeds, smoothing out the dots. This creates the illusion of a fixed, non-moving image. Blanking The technique of turning the laser beam on and off with precise control (as opposed to chopping). For scanned graphics blanking allows images to have disconnected sections where the beam is hidden. Blanking can be digital (on/off) or analog (continuous intensity control). Blanking can be performed with a third scanner, an acosto-optic modulator, or by electronically contolling the laser output as done with semiconductor lasers. ILDA Speed Ratings The International Laser Display Association has developed a standard to measure the performance of scanners and scanner driver cards. The two most common standard speeds for scanners is 12,000 points-per-second and 24,000 points-per-second while displaying the ILDA test pattern. Speed standards are designed to help make artwork compatable with different scanners and scanner amps. When displaying artwork that was designed for slower scanners on high-speed scanners, the points that make up the artwork may become apparent. To eliminate this the scanners must be tuned to a slower speed. Midwest Laser Products P.O.
