Part 4: Challenges Faced and Solutions during LaserPecker LP4 Product Development
Due to the different wavelengths of blue and infrared lasers, their refractive characteristics in the optical system vary. To ensure consistent focus in the laser engraving machine, optical system optimization was necessary. Overcoming this challenge involved adjusting optical components, particularly the lens system.
How did LaserPecker LP4 overcome these challenges? Here are some methods employed:
- Lens Selection: Choosing lenses suitable for both wavelengths. Different wavelengths interact differently with lenses, so selecting appropriately designed lenses ensures similar focusing characteristics at the focal point.
- Dual-Wavelength Lens: Using lenses specifically designed for multiple wavelengths to adjust the focal length to some extent, ensuring similar characteristics at the focal point.
- Adjusting Lens Positions: Fine-tuning and calibrating the optical system by adjusting the position of lenses or other optical elements.
- Use of Adjustable Focus Lens System: Equipping the laser engraving machine with an adjustable focus lens system that can manually or automatically adjust the focal length for different wavelengths.
Part 5. Expanding Knowledge: Types of Laser Light Sources
What are the types of laser light sources for diode laser engraving machines?
Diode laser engraving machines typically use semiconductor diode lasers as the laser light source. The types of these lasers are primarily categorized based on their working wavelengths. Here are some common types of laser light sources for diode laser engraving machines:
Infrared Laser Light Source: Some diode laser engraving machines utilize infrared lasers with wavelengths usually ranging from 700nanometers to 1100nanometers. Infrared lasers have advantages in specific engraving applications, such as engraving on transparent materials.
Blue Laser Light Source: Employing semiconductor lasers with wavelengths in the blue light spectrum, typically ranging from 450nanometers to 490nanometers. Blue lasers offer high resolution and precision in engraving, commonly used for materials like wood, leather, and paper.
Violet Laser Light Source: Using semiconductor lasers with wavelengths in the Violet light spectrum, typically ranging from 380nanometers to 450nanometers. Violet lasers create unique effects in certain applications, commonly used in making signs on transparent materials and biomedical applications.
