Choosing suitable galvo mirrors depends on several factors, including your application requirements, technical specifications and budget. Here's a guide to help you choose suitable galvo mirrors.
1. Galvo mirror Application Requirements
Scanning Speed: Determine the speed at which you need to scan or deflect the laser beam or light source.
Accuracy: Consider the level of precision required for your application.
Resolution: Determine the smallest incremental movement you need from the galvo mirrors.
Operating Environment: Consider factors like temperature, humidity, and vibration levels where the galvo mirrors will operate.
2. Galvo mirror Technical Specifications
Mirror Size: Choose the appropriate mirror size based on the beam diameter and scanning area requirements.
Reflectivity: Select mirrors with high reflectivity to minimize energy loss and maximize efficiency.
Coating: Ensure that the mirrors have coatings suitable for your wavelength range (e.g., UV, visible, IR).
Frequency Response: Consider the frequency response of the galvo mirrors, which determines how fast they can move.
3. Galvo Mirror Budget Considerations
Galvanometer mirrors come in a wide range of prices based on their specifications and quality. Determine your budget and look for mirrors that offer the best value within your budget constraints.
4. galvo mirror Supplier and Support
Choose a supplier known for providing high-quality galvo mirrors and reliable customer support. Sino-Galvo provide 2D / 3D laser marking, laser cleaning, laser welding, laser medical beauty galvo scanner, and provide 18 months warranty for most model.
