CO2 LASER LENS
How to determing focal length
The Focal Length is the distance between the lens and the cutting material.
The cutting requirements for different materials vary in terms of focal length. Typically, thinner materials require longer focal lengths, while thicker materials require shorter focal lengths. This is because the position of the focal point affects the focusing depth and diameter of the laser beam.

FIBER PATH
Cloudray Laser Lens
In the CO2 cutting process, the common optical path structure typically includes one focusing lens and two reflecting mirrors.
The focusing lens is located after the output coupling mirror and is primarily used to adjust the direction and shape of the laser, making it as symmetrical as possible, and guiding the laser beam to the subsequent reflecting mirrors.

Important Consideration
Cleaning Instructions
1. Use appropriate cleaning materials: Use gentle cleaning materials such as lens cleaning solution or lens cleaning tissues specifically designed for optical surfaces.
2. Clean in a dust-free environment: Ensure that the cleaning process is carried out in a clean and dust-free environment to prevent particles from getting onto the lens surface during cleaning.
3. Avoid excessive force,Excessive force can cause damage to the lens or misalignment of its optical properties.

CO2 LASER LENS
CO2 Lens Testing
Ensuring lens quality: CO2 lenses undergo high energy and high temperature in laser cutting processes, so their quality and durability are crucial. Testing can ensure that the lens materials, manufacturing, and coatings meet the quality requirements.

CO2 LASER LENS
Excellent Performance
Determining optical performance: The optical performance of CO2 lenses is highly
important for cutting and laser transport efficiency and quality. Testing can be used to evaluate optical performance parameters such as transmittance, reflectance, and scatter to ensure the proper functioning of the lens.
Detecting surface conditions: Testing can be used to detect scratches, dirt, or other defects on the lens surface.

Centering Tolerance Test
In summary, CO2 lens testing can ensure that the lens quality, optical performance, and surface conditions meet the requirements, thus guaranteeing cutting quality and equipment reliability.

Way better than dishing out a ton of money for a laser lens. These work great. Nothing else to say really. They fit in my machine, they work great, and I haven't had any issues with cracking or it getting cloudy. Will definitely buy again.

Works great with my machine. I have a polar laser by OMTech and I love it

I have a 70 watt boss ls14x20 and dropped it in adjusted a focus and boom! No reason to spend the 90$ boss laser wants to charge u for the same lens

I purchased some Ten-High lenses and some Cloudray lenses to check the quality of both. The Ten-High laser lenses are cloudy, but the Cloudray lenses are nice and clear and crisp. Not conviced? Look at the low rating reviews for Ten-High lenses. I'll never buy from them again. Good job Cloudray!

Bought this to replace the stock lens in my K40 laser in addition to the Si mirrors and have been impressed by the results. I have never heard of the company Cloudray but I decided to take a risk since this lens was a bit cheaper than the alternatives (who similarly had names that I have not seen). If this lens is in fact a CVD ZnSe that is advertised, then the value (i paid 20) is quite good. I definitely have significant improvement in cutting/engraving performance over the stock lens and it has held up well so far.I'll go ahead and say that this was a good purchase for my situation - the specs say it is good for up to a 200w laser and considering how big a difference I've seen in my performance it would be interesting to see how true that is.If you're on the fence trying to find a safe lens then I would just go for it - I think most people will be happy with this lens.
