Care information

High care information about CO2 laser lenses, fiber laser protective windows, and
fiber laser lenses is essential to ensure the optimal performance and longevity
of these critical components in laser systems. Here are some key points to consider:

CO2 Laser Lenses:

Regularly clean CO2 laser lenses to remove dust, debris, and residue. Use a
soft, lint-free cloth or lens cleaning tissue. Avoid using abrasive materials
that may scratch the lens.

Always handle CO2 lenses with clean hands or lint-free gloves to avoid transferring oils or contaminants onto the lens surface.

Store lenses in a clean, dry, and dust-free environment to prevent damage and
maintain their integrity.

Properly align CO2 lenses within the laser system to ensure efficient laser
beam delivery and focus.

Regularly inspect lenses for signs of damage, scratches, or deterioration.
Replace any damaged or worn lenses promptly.

Laser Protective Windows:

Clean fiber laser protective windows with care to avoid scratches. Use a gentle
cleaning solution and a soft, lint-free cloth.

Keep protective windows in place when the laser system is not in use to prevent
contamination and damage.

If protective windows become damaged, replace them immediately to maintain
laser system safety and performance.

Fiber Laser Lenses:

Clean fiber laser lenses carefully to prevent damage. Use a lens cleaning
solution and a soft, lint-free cloth or lens tissue.

Handle fiber laser lenses with care to avoid fingerprints, oils, or scratches
on the lens surface.

Properly align fiber laser lenses to ensure accurate laser beam focusing and
efficient performance.

Regularly inspect fiber laser lenses for signs of wear, damage, or contamination. Replace any compromised lenses promptly.

Environmental Considerations: Be mindful of environmental factors such as temperature and
humidity, as extreme conditions may affect lens performance.

maintaining high care and attention to detail when handling, cleaning, and
storing CO2 laser lenses, fiber laser protective windows, and fiber laser
lenses will enhance their longevity and contribute to the smooth and reliable
operation of your laser systems. Always follow the manufacturer's guidelines
and best practices for each specific component to ensure optimal results.

Happy with the results.

Bill Latham
Amazing customer support

First, the products are top quality. I purchased the 4 piece kit for my Omtech 2028 and it's working flawlessly. The customer support is just as good or better. I made a mistake and ordered the wrong kit (16mm vs 16.15mm). I contacted them, explained how I made a mistake and Lou contacted me the next morning. He fixed everything and I had the correct set within a couple days. Highly recommend.

Patricia Larouche

I was not impressed with the additional charges when I received my item. I spent $340 Canadian for the lens and shipping -- Then charged an additional $95 for brokerage./ duty. I will not order again

Hi Patricia. I'm sorry that you were charged a high amount in duty and brokerage fees. American Photonics is not able to control the fees that the shipping provider charges for international orders. We offer multiple shipping methods so that the customer can choose what is best for them, but our shipping policy states that 'any potential extra charges, such as customs, duties, or taxes may apply depending on your country's regulations.'


Awesome customer service, Great product!
