A visible laser diode scanner is a type of optical scanning device that utilizes a laser diode to create a visible laser beam for scanning and capturing images or data. It is commonly used in various applications such as barcode scanners, 3D scanning, and document scanning.
The term "visible" refers to the fact that the laser beam emitted by the scanner is within the range of the human eye's sensitivity, typically in the range of 400 to 700 nanometers (nm). This allows the laser beam to be easily seen by users, aiding in the alignment and operation of the scanner.
The core component of a visible laser diode scanner is the laser diode itself. A laser diode is a semiconductor device that emits coherent light when an electric current is applied to it. In the case of a visible laser diode scanner, the laser diode is specifically designed to emit light within the visible spectrum.
The scanner's laser diode emits a narrow beam of laser light that can be rapidly moved across a target object or surface using mirrors or other scanning mechanisms. By precisely controlling the movement of the laser beam, the scanner can capture detailed information about the object being scanned.
The captured information can then be processed and used for various purposes, including decoding barcodes, creating 3D representations of objects, or digitizing documents. Visible laser diode scanners are known for their accuracy, speed, and reliability, making them a valuable tool for industries that require precise and efficient scanning capabilities.
