Why Choose Uncoated Molybdenum Mirrors

Key Advantages of Our Molybdenum Laser Mirrors

• 99.95% High Purity Molybdenum Substrate: Made from premium 99.95% high purity molybdenum with excellent thermal stability and mechanical strength. Provides consistent performance even in harsh industrial environments.
• No Coating - Never Peels or Flakes: Uncoated precision polished surface eliminates the risk of coating peeling or flaking, a common problem with coated mirrors. Ensures long-term stable reflectivity.
• Extremely Scratch Resistant: Molybdenum has a Mohs hardness of 5.5, making it much harder than silicon and gold coatings. Can be wiped repeatedly without damage, ideal for high dust environments.
• Repolishable Design: If the surface becomes oxidized or slightly scratched, it can be easily repolished to restore original reflectivity, extending service life by up to 3 times.
• Stable >98% Reflectivity: Provides stable >98% reflectivity at 10.6μm (45° angle of incidence), perfect for all 40-100W CO2 laser applications.
• 5 Standard Specifications: Complete range of diameters available, covering all mainstream desktop CO2 laser machine models and application requirements.
• Universal Compatibility: Standard dimensions ensure perfect fit with all original and compatible CO2 laser mirror mounts. Easy to install and replace with no additional debugging required.

Frequently Asked Questions

Q: Why don't molybdenum mirrors need a coating?
A: Molybdenum has natural high reflectivity at 10.6μm wavelength. Unlike silicon, which requires a gold coating to achieve high reflectivity, molybdenum can be used directly after precision polishing. This eliminates the risk of coating peeling or flaking, a common failure mode for coated mirrors.

Q: How do I repolish a molybdenum mirror?
A: If the mirror surface becomes oxidized or slightly scratched, you can repolish it using a fine diamond polishing compound (3-5 micron) and a soft microfiber cloth. Gently polish in a circular motion until the surface is shiny again, then clean with lens cleaning fluid. This can restore the mirror to almost new condition.

Q: When should I choose molybdenum mirrors over silicon mirrors?
A: Choose molybdenum mirrors if you have a 40-100W desktop laser, are a beginner, operate in a high dust environment, or want the most durable and low-maintenance option. Choose silicon mirrors if you have a higher power laser (>100W), require maximum cutting speed, or operate in a production environment.

Q: How long does a molybdenum mirror last?
A: Under normal operating conditions, an uncoated molybdenum mirror should last 12-24 months. With proper maintenance and occasional repolishing, it can last up to 3 years or more, which is 2-3 times longer than coated silicon mirrors.

Q: Can I use molybdenum mirrors for cutting metal?
A: Molybdenum mirrors are not recommended for metal cutting applications. Metal cutting produces a lot of sparks and debris that can damage the mirror surface. For metal cutting, we recommend using gold coated silicon mirrors.

Also available: High Reflectivity Gold Coated Silicon Mirrors for higher power and production applications.
