Your Guide to Laser Technology
Lasers are used in many things that we come across in our daily lives. Since it was invented, people have taken advantage of its usefulness in a variety of applications, including in consumer electronics, information technology, science, medicine, industry, law enforcement, entertainment, the military, and even for personal use. Nowadays, different gadgets and devices which incorporate the use of lasers are readily available in the market.

Laser printers have many significant advantages over other types of printers because they are capable of rapidly producing high quality text and graphics on plain paper. But choosing the right printer can be a daunting task. First of all you need to know which laser printer is suited to your printing needs:
- Monochrome Laser Printers - for printing black-and-white text or graphics
- Color Laser Printers - for lots of graphic-heavy materials
- Multifunctional Laser Printers - for scanning, copying, or faxing documents.
It is also important to take note of the printer's specifications, such as its resolution, printing speed, and paper handling capacity:
- Resolution - measured in dpi (dots per inch). The higher the number of dpi, the sharper the results.
- Printing speed - measured in ppm (page per minute). Consider the number printed pages per minute and how long to start print the first page.
- Paper handling - see the number of pages and the size of paper the laser printer can handle. The best laser printer is rated by the number of printed page it is expected to produce per month. Make sure the printer meets your workload requirements and suit with your paper size needs.
Rangefinders are devices which can help establish the distance of the observer to a target or object. They come in many shapes and sizes: large, small, waterproof, and digital, and combined with other devices such as binoculars or digital cameras. Rangefinders have different capabilities and performance levels. They also suit particular uses or sports. To get the right kind of rangefinder, consider the type of activity in which it will be used most frequently.
Laser diodes are, numerically, the most common type of laser, which is widely used in telecommunications, various measuring instruments, barcode readers, printing industry, image scanning, optical data recording, and many more.
Hair Removal Lasers
Hair removal is another popular application of lasers. Thinking of tweezers and razors, this fact is, without a doubt, a breath of fresh air for people who always suffer under painful hair removal sessions. The best part is with modern technology, it is now even possible to be done at the comfort and privacy of your own home.
These devices are relatively safe...if used properly. But before spending a substantial amount of money on laser hair removal kits, look very carefully into the model. Take into consideration any allergies you may have and fully read the instructions and precautions before using. Laser is a very delicate material to work with, so utmost caution is advised.
Fiber Optics Sights
Fiber optic sights are becoming popular for shotgun and archery enthusiasts, as they gather available light and concentrate it at the ends of the fibers, making it much easier to see in limited lighting situations.
When choosing a sight, make a checklist of the features you desire the most. Bright, durable and adjustable – these are just some of the factors that you need to consider when buying fiber optic sights.
Laser scissors are simply modern scissors, but with an interesting catch. It uses lasers to guide cutting in a straight line. It is very easy to use; all you have to do is to follow the beam for a perfectly straight cut. No more jagged, zigzag, diagonal, or crazy cutting for you!
Laser levels are replacing water levels and transit compasses on modern construction sites. The most important thing to consider when buying laser levels is accuracy. The stated accuracy of the level is a function of the distance between the level and its target. All accuracies for laser products are specified along with their effective range.
- Rotary levels - shoot a rotating dot to create a 360 degree line. They also usually come with a detector to assist in reading the hard to see laser lines outdoors.
- Line levels - (point to point levels) shoot multiple horizontal and vertical laser lines. These levels are for indoor use, and usually include plumb up and plumb down functions.
- Single line lasers - shoot a single line, and usually have a more restricted range.
- Point generators - levels which shoot a single laser dot. They may sometimes include a line generator that can be flipped down in front of the beam.
Laser Stud Finders
Another convenient modern tool is the laser stud finder, which can measure distances and detect studs. Laser stud finders can be used with wood or metal. Some stud finders not only mark stud locations, but can detect and identify separate materials behind walls, such as rebar, wiring, metal studs, wood studs, etc. However, they cost more. The key to choosing the right device lies in understanding your current and future needs, whether you need the device for more than just finding studs or not.
The laser mouse is the most sensitive mouse-style data entry device available for computer users today. Aside from the fact that it is more sleek and fashionable than an old computer mouse, it is much more efficient and saves more cleaning time.
The most important thing to consider when buying a laser mouse is ergonomics. Look for a mouse that sits comfortably in your hand and does not stretch your fingers too high to cause overextended curvature of the hand, or that your fingers have to move too much to reach the scroll wheel.
Radar detectors come in all shapes, sizes and colors. Some are dash-mounted, some are wireless, and some are remote-mounted. Laser guns or Lidar (Light Detection And Ranging) work much like a radar detector, but instead of radio waves, it shoots out bursts of invisible light. When buying a radar/laser detector, you may consider buying a corded/cordless, dash-mounted or concealed one. The features, which are important to the user, must also be noted, such as overall performance, POP, GPS equipped, three band or twelve band.
Lasers can also be found in thermometers, especially in a certain kind known as the infrared (IR) thermometers. These are also known as pyrometers and non-contact thermometers, and are used to measure the temperature of things that would be difficult to measure with conventional thermometers. An important feature that is standard on most instruments like these is a laser pointer. This assures that the correct point is measured particularly with instruments with a large spot ratio.
Lasers can be very helpful in your everyday life… as long as you know how to use them carefully and properly. Pick the right laser equipment for you!
