Demystifying Laser Light: Understanding Key Terminology
Laser technology is filled with intricate specifications and unique attributes that can be overwhelming for those in search of the perfect laser light projector. To help you navigate through these critical details, we've put together this article to explain common laser terminology using clear language and real-world examples.
Wavelength and Color
A fundamental characteristic of lasers is their wavelength, measured in nanometers (nm), which determines their color. Here's a breakdown of some common wavelengths and their corresponding colors:
405nm – Violet
532nm – Green
638nm – Red
445nm – Royal Blue
650nm – Deep Red
For laser light projectors that showcase multiple colors, DJ laser lights combine different wavelengths like red, green, and blue into a single unit or use wavelength mixing to create a spectrum from a single laser diode.
Scan Rate (KPS)
Scan rate, often referred to as KPS (kilo scans per second), measures how quickly a laser can project animations and graphics with precision:
Low-speed lasers below 4KPS are ideal for simple beam effects.
High-speed lasers rated at 12KPS or more are perfect for club settings with intricate graphics.
A scan rate of 20KPS supports highly detailed animations, including complex logos or text.
Diode Type
Laser diodes are crucial for generating laser beams. Common diode types include:
IR Diodes, emitting infrared wavelength beams that are invisible to the naked eye.
RGB Diodes, producing visible red, green, and blue laser beams.
Laser Modules, integrating multiple diodes and optics into a unified unit.
Top-notch diodes from reputable brands such as Osram ensure optimal efficiency and brightness.
Scanner Type
Scanners direct and control laser beam movement through mirrors. They come in several types:
Galvo Scanners swiftly steer beams using micro-mirror movement, ideal for graphic displays.
Polygon Scanners use rotating optics for faster and more complex laser effects.
Hybrid Scanners combine features of both types for enhanced versatility.
High-quality mirrors enhance scan rates and accuracy.
Optical Power
Optical power measures the output of the laser diode in milliwatts (mW). Higher power results in brighter projections:
Class 3R lasers emit less than 100 mW.
Class 3B lasers range from 100 to 499 mW.
Class 4 lasers emit 500mW or more.
Choosing the right power depends on venue size and lighting conditions.
Beam Count
Multiple laser diodes allow for simultaneous projection of beams in different colors. Beam count indicates how many beams a unit produces. For example, lasers with three beams emit separate red, green, and blue lasers.
More beams offer richer effects but typically come at a higher cost. For DJs, lasers with three or five beams strike a good balance.
Control and Programming
In addition to manual controls, laser projectors offer various programming options:
DMX Control connects lighting consoles to choreograph shows, sync motions with music, and integrate with other light fixtures.
ILDA uses PC-driven software for projecting graphics, text, and animations.
Standalone modes include built-in features like sound activation and automatic patterns.
Choose a programming method that suits your needs and technical expertise.
Key Takeaways
Understanding laser terminology, including wavelength, scan rate, power output, and control modes, is crucial for selecting the right laser light projector for your DJing needs. Armed with this knowledge, you can make informed decisions that enhance your events.
We hope this breakdown has clarified laser terminology and will guide you in choosing a professional laser projector. For expert advice on selecting the perfect laser for your event, feel free to reach out to NEWFEEL laser.
