Do you want to add more jazz to your presentation? Or are you an amateur astronomer? From educational and business to fun purposes, a laser pointer, also known as a laser pen, can come in handy in many situations. Whereas, a red laser can be used indoors, a green laser can help you in astronomy classes to point out the stars on a moonless night.
Laser Pointers – cool and handy devices
These little devices are super portable and can easily fit into a person’s palm. Once upon a time they were regarded as some kind of futuristic object. But today, they have become quite ubiquitous and a variety of laser pointers in different models and makes are available in the market. Different kinds of laser pens have different features suitable for different needs like the size of the pointer and the power of the laser. Some of these cool devices also come with USB gadgets and ball pens. Depending on your budget and preferences, there is a laser pen out there that will be perfect for your needs.
Types of lasers pens
Laser pens with red laser beams are perhaps the most common types that you can find online. But with the advent of technology other wavelengths in laser pointers are being safely recreated and more color choices are becoming readily available. But you must bear in mind that different colors of laser beams have different functions.
Red laser pens
Laser pens with red beams are the least expensive types, as the wavelength of the red color can be recreated more easily than the other colors in the spectrum. These are usually used in small pointers.
Green laser pens
Usually more expensive and also more powerful than their red counterparts, laser pens with green beams are increasingly becoming popular with the astronomy groups. These pointers are very bright and can be noticed from a great distance.
What to look for in a laser pointer?
The power of a laser beam usually decides what task it is most suitable for. Laser beams are usually measured in milliwatts or mW. So the higher the mW, the more powerful your laser pointer is going to be. The next step towards choosing the right pointer is to decide on the size you want to go for. Many are portable and come with key chains. The small ones can also be easily stored in your pocket and taken out whenever needed.
