About CO2 LENS D20 F63.5

CO lenses are optical lenses specifically designed for use with CO lasers, which emit light in the infrared spectrum (typically around 10.6 micrometers). These lasers are commonly used in cutting, engraving, welding, and medical applications.

Because CO laser light is invisible and has unique absorption properties, the lenses used must be made from materials that are transparent to infrared radiation.

Q1. What is the primary use of CO lenses?
A: They are used in CO laser systems to focus or shape the infrared laser beam for applications like cutting, engraving, welding, and surgery.

Q2. Why is ZnSe commonly used in CO lenses?
A: Zinc Selenide transmits infrared light very efficiently and can handle the heat generated by high-power lasers. It also allows for the application of anti-reflective coatings.

Q3. How do you choose the correct focal length for a CO lens?
A:

• Shorter focal length (e.g., 1.5"): Smaller spot size, higher precision good for engraving.

• Longer focal length (e.g., 4"): Deeper focus and wider cut good for thicker materials.

Q4. How do you clean a CO lens?
A: Use optical-grade lens tissue and a cleaning solution (like acetone or isopropyl alcohol). Always wear gloves and avoid
