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.

Overall, my experience with AP has left me thoroughly disappointed. I needed an upgraded lens kit for a large bulk order (200+) and sought advice from AP regarding compatibility with my specific machine. After a prompt response, I purchased the recommended product via the provided link. Despite the quick delivery within 5 days, upon arrival, it became apparent that the product was completely incompatible with my machine.

Upon contacting AP to address the issue, they acknowledged the mistake and directed me to a different product. However, rectifying the situation required me to bear the cost of return shipping, and while they offered a gift card equivalent to the original purchase price (minus shipping and taxes), it was hardly compensation for the inconvenience caused.

I used the gift card to purchase the correct product, but was dismayed to find I still had to cover taxes and shipping. This entire process not only resulted in additional out-of-pocket expenses but also wasted two weeks of my time. The lens kit did not arrive in time for our bulk order production, causing further delays and frustration.

What disappointed me the most was the lack of accountability from AP’s staff. Despite their initial misinformation, there was no apology offered for the inconvenience caused. Good customer service is paramount, and this experience has shown that even a quality product cannot compensate for poor communication and service. First impressions may not be everything, but they are certainly enduring, and unfortunately, my first impression of AP has been marred by this experience


As described. Gast shipping Also gave good information

Enrico Forlini

Very impressed with the quality of the 2.5 inch nozzle and gold mirror kit for my 80 watt Omtech, the machining of the kit screams quality and there’s a nice noticeable improvement over the stock items!

Walter Sowers
Amazing kit

I bought the 4 lens kit with the adapter for my Omtech and I have had exceptional results so far. The fact that I can leave my autofocus the same on all of the lenses is icing on the cake. The 1.5 inch does some great photo work and I can dive straight thru the 3/4 plywood with the 4 inch lens. Great products! Very pleased so far.

Jeffrey Sgrignoli
Best lenses I've used yet.

These are the best lenses I have purchased for my OMTech 2028-80 laser yet. the cut and engrave quality is excellent compared to the single lenses I have purchased elsewhere.
