American Photonics Lens: Approved by Laser Experts and Manufacturers

For the best-infrared optics, we choose CVD ZnSe from the USA. It is the best material. PVD ZnSe and GaAs from China are of low quality. OMTech and AP laser specialists tested and approved our focal lenses on their machines.

Introducing the new 18 mm Lens:

A 100% American-Made Option with Glue, Aluminum Mount, and Better Thermal Conductivity

1. Labeled Lenses: No More Guesswork with Focal Length

You don’t have to guess the focal length of your lenses because we label them.

2. Position Your Lenses with Confidence Using BIM IN Markings

You can easily position our lenses because they have BIM IN markings.

3. The Benefits of Glue for the Lens: No O-ring, No Stress, and No Power Loss

The glue keeps the lens stress-free and eliminates the need for an O-ring. Our lens prevents you from over-tightening it, causing power loss, lens overheating, and beam distortion.

4. Clean the Lens with Ease and Protection Using the Aluminum Mount

You can easily protect and hold the lens when cleaning with the aluminum mount.

Top 10 reasons why a lens fails?

1- Not cleaning the lens often enough.

2- Water in your air assist.

3- Oil in your air assist.

4- Accidentally left off the air assist.

5- Overtightening your lens (not using an O-ring).

6- Using cleaning products containing water or dies.

7- Poor beam alignment causing the head to overheat.

8- Dropping or chipping the lens while cleaning it.

9- Use of cheap nonlaser grade ZnSe.

10- Poor coating and optical quality.

Upgrades to consider.

Good air compressor
Desiccant filter or air dryer
Coalescing filter
Automatic air off and on

How to select the correct lens for the job and optical setup

Optical setup

The best possible optical setup for your machine and the truth about the compound lens system.

I computer model and manufacture Infrared optical systems. The best possible setup would start with perfect beam alignment. Poor beam alignment combined with a multiple-element system (compound lens) could give you a worse focal point than a single-element system (single lens). The second most crucial thing is optical quality. Differences like material, edge thickness variation, sphericity (how perfect each radius is), and surface quality. These are particularly important if you want the best setup for your machine. Errors in the optics are compounded in multiple-element systems. Compound lens systems are better on paper. But if you work first on beam alignment and get the best possible optics for your system, you save money. After focusing on beam alignment and optical quality, your engraving quality is as good as Epilog or Trotec. They are single-element systems. Here are some backup links to what I am saying.
