laserkeilain

Laserkeilain is a Finnish term that translates to "laser pointer" or "laser device." It refers to a portable handheld device that emits a narrow beam of visible light, typically red, green, or blue, produced by a laser diode. These devices are commonly used for a variety of purposes, most notably as a presentation tool. When pointed at a surface, the laser beam creates a small, bright spot that can be used to highlight specific areas of interest on a screen or diagram during lectures, meetings, or other presentations.

Beyond presentations, laserkeilaimet find applications in other fields. They can be used for pointing out objects at a distance, for example, during astronomy or outdoor activities. In some industrial or construction settings, they might be employed for alignment purposes, though more powerful and specialized laser alignment tools are typically used for precision work. Some laserkeilaimet also come with added features such as interchangeable "star caps" that project patterns of light, or in combination with other tools like clickers for presentation control. The intensity of the laser beam is usually low, intended for pointing rather than cutting or burning. However, it is important to exercise caution and avoid directing the beam into the eyes, as even low-power lasers can cause temporary or permanent vision damage.
