A laser video projector is a product that takes a specific video signal and then converts that video signal to a modulated laser beam. Once the signal has been converted, the beam will project moving images. Laser video projectors currently product the highest variety of colors when compared to other display options. The very first laser video projector was used back in the 1970s. During this time, the very first laser projector was created and used in a movie theater. This laser featured 164 ion lasers and was created with a Spectra-Physics design. The creators of this laser used specifically designed output mirrors that produced simultaneous wavelengths in colors of red, green, blue and yellow. The beam that was produced by this laser looked white to the human eye. To separate the colors of blue and red, the beam was subjected to a high refractive index prism. This helped to separate the two colors by two degrees between each shade. This first laser video projector was a much larger model than what is used today. It was enclosed in a cabinet that measured over two feet squared and more than six feet high.
Projectors today however, have become much more advanced than this first creation. Many businesses and homes use laser video projectors and there are now several different types of projectors available. Choosing one will depend on your specific needs such as your budget as well as the specific features that you need and the purpose of your projector.
If you are planning to use a project for conference rooms or business meetings, then conference room projectors are the best choice. These are much brighter and can be adjusted for larger rooms and crowds whereas other projectors are more specifically geared for other purposes. There are a variety of models available such as laser pointers, computers and other necessities.
Since portability is a must today for many businesses, an ultra-light projector may be the best choice, depending on your specific needs. Those who give presentations frequently may find the lightweight portability of this type of projector a much better fit. Many manufacturers release newer and lighter versions of portable projectors every year and currently, you can find one of this style that weighs less than three pounds overall.
Micro-portable projectors are also available and are designed for those business individuals who like to keep things mobile. This type of projector is also very lightweight and newer versions have excellent brightness as well as many other features.
When purchasing a laser video projector, there are many things to keep in mind. You should first set your budget so that you know exactly how much you have to spend. Once you have your budget in mind, you can begin to look at various models and choose the features that are most important to you. Keep in mind that the quality of the projection will depend on the projector’s features such as type of lamp, brightness and the projection surface.
If you choose a projector that does not have sufficient brightness, your images may become blurred or distorted. Brightness for projection is measured in ANSI lumens. When choosing a new video projector, try to choose one that offers at least 1,000 lumens, more if you plan to use the projector in a fairly large room. You should also keep in mind that the best surfaces for projecting video is screen rather than a wall. Once you have chosen your projector, it is important that you ensure you are using the correct screen to give your projections the best quality. Finally, try to choose lamps that have lower wattage. These are much more economical and will last much longer. You may opt to purchase a projector that offers an economy mode feature. This will help you to prolong the life of your lamps significantly.
