Tips for choosing and using a powerful laser pointer

Jun 2nd 2015 at 1:27 AM

Your professional and personal lives involve routine. You may consider a laser pointer to break the momentum. Laser pointers greatly enhance work-related tasks, and transform a lifeless party into a thrill-filled one.
If you wish to make a laser pointer part of your work or home-tool arsenal, do think carefully about what you will use it for. If you have never owned a laser pointer, you will find these suggestions for choosing one helpful.

Uses of laser pointers

The laser pointer's versatility will surprise you. This nifty, functional device has professional and creative uses.

If you are about to embark on a home improvement or building project, you will find a laser pointer indispensable. These devices are useful for pointing out nitty-gritty construction details. They are particularly handy for minute structures tucked away in dark, shrouded corners. If the construction project you are undertaking is a major one, you will find these pointers useful. Built into distance measuring tapes, they can focus on targets that are difficult to reach. They are precise tools when used over long distances.

Laser pointers are must-have accessories for office presentations. They highlight essential points on Powerpoint slides and help to focus an audience. If you are a student who needs to make Powerpoint or internet-based presentations, you will find this an extremely functional device.

Green laser pointers are especially useful if you are passionate about astrology and stargazing. Green pointers are ideal for identifying celestial objects, as they are highly visible in the dark. Their laser beams point directly to a star you want to highlight. You can attach them to telescopes to align them with stars.

You can also use them with animals. Feisty animals find chasing laser dots amusing. You can also find animals in dark corners.

If you want to stretch the abilities of the laser pointer, try playing laser tag. This usually needs special electronics and scoring software. User-friendly, laser-tag software is easily available over the internet.

Laser lights are available in a multitude of colors, so they are useful for creating light shows that will mesmerize children. This is not limited to fancy laser shows at stadiums. If everyone at home has a pointer of a different color, clear a space on a light-colored wall. Participants should sit some distance from each other, in a row, to avoid contact with laser beams. This can give hours of entertainment.

Old laser pointers that you have not pulled out for some time have their uses. With the long exposure mode on your camera, you can take spectacular photographs. Simply turn the lights off, release your camera's shutter and wave the pointer. You will capture bizarre, abstract visuals.
If you have painted a wall with glow in the dark paint, the pointer will excite it. A strong blue or ultra-violet pointer will make this extremely effective. Combine a laser tripwire with various trip points, lasers and mirrors to make a maze. This tripwire is the beginning of a haunted house for Halloween. Lasers illuminate objects, creating scary images. You can shine the pointer through a water droplet to make a simple microscope. Use this to focus on minute objects. Suspend it carefully on the end of a skewer before focusing on the object.


When using a laser pointer, you should always have safety in mind.Never aim the pointer at any person or animal, especially if it is of a high wattage. Eyes recover from light exposure only after 30 minutes. It blinds people and animals within seconds. Burning fires with lasers is hazardous. A fire started with a laser is difficult to extinguish. Many use pointers to add to the thrill of an airshow. While it is amusing to watch an airshow at night, never aim a pointer at an aircraft. This may blind pilots permanently.
You should only run Class 3 pointers while wearing protective gear. You may suffer from blindness and other injuries if you do not wear goggles.

How to choose a laser pointer
Laser pointers have a multitude of uses, but you must choose them carefully. Each pointer suits different situations and needs.
1. Decide on the pointer's color and wavelength.
The first order of business is to decide on the pointer's color and wavelength. Blue, red and green are the most common colors available. Red usually runs at a wavelength of 660mm, blue at 473 mm and green at 532 mm. Yellow, a more unique color, runs at 593.5 mm. Should you want a colorless, infrared pointer, invisible ones run at 1064 mm.
2. Consider its power requirements.
You should also consider the pointer's power requirements. If you need a simple pointer for use at home, a standard device that functions at 3-5 mW suffices. For highlighting objects, brighter pointers that run at 35 mW or a higher wattage are better. If you are a professional looking to create powerful laser shows, 400 kW devices, a hundred times more powerful than standard pointers, are readily available.
3. Consider its peak and sustained outputs

Find out the pointer's peak and sustained outputs. A pointer's power rises and declines. Sustained output refers to the highest amount of power a pointer has over time, while the peak output refers to the highest amount of power a pointer has before it begins to decrease. This allows you to decide how long you can use it for.
4. Find one of the right size.
When choosing a laser pointer, it is important to find one of the right size. Outdoor enthusiasts who carry large backpacks while on hikes will want to carry simple, light, key chain pointers. These are highly portable and are ever ready. Pen laser pointers are useful for office presentations. Manufacturers incorporate many with pens, which users can slip easily into their pockets. Slightly bigger than key chain pointers, they are comfortable to hold during presentations. Heavier, hand-held pointers are also available. Though these are not for use outdoors, they make useful laser lights in garages or workrooms.
5. Consider its cost-effectiveness
It is also wise to consider a pointer's cost-effectiveness. Higher wattage pointers will cost more. If cost is an issue, compact, red laser pointers are available at low prices. These often cost less than $10. If you need one for extensive use in basements or workrooms, larger hand-held ones that you should use only with safety goggles are available.
