Presentation Lasers
Lasers make pointing within a classroom or business environment as simple as pressing a button. Instead of pointing to the projection or LCD screen with your index finger, which gets tiring especially if the screen is large, you can point to your presentations standing in one location. Our lasers are also wonderful tools for tour guides, docents, and outdoor travelers.
In 2009, SKYlasers cooperated with a courthouse in the United States. Photo evidence was being shown to the jury on LCD televisions in a murder trial. As regular lasers were not bright enough to be visible, the prosecutor had sent us an email asking for a solution. We shipped several 15mW green lasers for them to use which worked out wondrously. The courthouse gave us an update after the trial. The murderer is now behind bars.
Not all high power lasers are suitable for presentations. You must choose the appropriate color and power output depending on the nature of your presentation and the room size.
Choosing a Laser Color
1. High power lasers are available in a multitude of colors, most commonly, red, blue and green. Each color varies in brightness and costs. All colors are suitable for presentation purposes, choose the color you like most.
2. The human eye is most sensitive to the color green. Therefore, you will find green lasers to be the brightest. Green lasers at low power outputs can easily show up on projectors, televisions, and LCD monitors.
3. Red lasers are the lowest in cost. Green lasers are more expensive than red lasers. The most expensive are blue lasers due to the high cost of crystals within the blue laser diode.
Determine Power Output
A green laser is a good choice for conducting presentations due to it brightness. For smaller classroom or meeting room settings, stay with our lower powered models between 15mW to 35mW. A green laser at this power range will easily show up on bright LCD / projection screens. Our next models up, the 55mW green laser and above are extremely bright and should be considered only if your presentations are conducted in large classroom, auditorium, or outdoor settings. These higher powered lasers also make excellent astronomy lasers.
While the laser spot of our green lasers are clearly visible under daylight, the laser beam is only visible in darkened conditions such as low lighting or complete darkness. As you increase in power, the laser beam and spot will increase in intensity and brightness. To compare the brightness of our laser models, check out our section on laser beam comparison.
Red lasers are cheaper, however, more power is needed to achieve the same brightness as green lasers. This is because the human eye is much more sensitive to the color green. We offer two red laser models, a 50mW and 80mW version. The 50mW red laser is suitable for smaller enclosures such as classrooms and meeting rooms. The 80mW red laser is suitable for long distance pointing in large classrooms, lecture halls, auditoriums, and outdoors.
