Products Description
10.6μm CVD ZnSe CO2 Laser Focus Lens Infrared Lenses For Laser Cutting Engraving System
Co2 Laser Focusing Lens is an indispensable part of the CO2 laser processing systems and other kinds of light converging applications. CVD Znse focus lenses is the prior choice for high power CO2 laser systems due to its particularly low absorption for the 10.6μm laser beam.

YONGLI selects CVD (chemically vapor deposited) ZnSe grown in America, which features extremely low bulk losses induced by absorption and scatter, exceptional homogeneity, high thermal shock durability, and stability under harsh operating conditions.

The relatively high refractive index of Znse Selenide implies that anti-reflection coatings are crucial for ZnSe lenses, correspondingly, our AR coating ensures a high damaging threshold, high durability, and high abrasion-resistance, with an excellent transmittance of T≥99.5%@10.6mm.

Product Details
CVD ZNSE FOCAL FOCUS LENS FOR 0-200W LASER ENGRAVER CUTTER
ZnSe lense is widely used in CO2 laser cutting ,marking,drilling,other laser system of industrial, which has low absorption and withstand high laser power.The coating layer of ZnSe lense is solid.The trasmission of it can reach 67 % in 10.6 micron.

We do the optimization design according to diffration and aberration and then show the products that have actual focus spot size in the same focal length. We can produce the products upon your requirement.

We take the import ZnSe which is yellow transparent multi-crystal to be coating. Its trasmittance is 0.5-15μm. It is made in chemical vapor deposition method,which have little inclusions and low obsorption. Its has feature of low scatter loss. It is the best substrate that can make IR lenses to use in CO2 high power laser system because of low absorption in 10.6μm.
HIGH-QUALITY CVD ZnSe
YONGLI powerful focus lenses are manufactured from premium zinc selenium(Znse) via chemical vapor deposition for superior optical properties.

* HIGH TRANSMITTANCE: Both sides of each lens are covered with strongly anti-reflective coatings to achieve at least 99.5% transmittance rate for infrared light at a wavelength of 10.6 microns.
High Quality OEM Optical CVD Znse CO2 Laser Focus Lens
* LASTING DURABILITY: Our laser engraver focus lenses' double-sided coating process also ensures outstanding scratch resistance for longer service life.
* WIDE COMPATIBILITY: This CVD ZNSE laser focus lens fits YONGLI 40W-200W CO2 laser engravers. Please check the focal lens diameter in your machine’s manual before purchasing.

CO2 Laser Engraving and Cutting Machine Focus Lens

* EASY TO USE: The plano-convex shape of YONGLI's laser engraver focal lens lets you install it easily and correctly onto your machine in the proper orientation. Detailed cleaning instructions also help you take proper care of your lens.
• The stability of focus position strengthened, the cutting & engraving speed of some applications improved, and the ability for reflected light enhanced;
The lens consist in many advantages such as precise focus, thin-film coating anti wiping, higher luminous flux, etc. For which materially improves your work efficiency.

CO2 laser cutter lens ZnSe Lens Laser Focus Lens Feature

• Stable focus spot, better effect in cutting and engraving, bearable for high power density, and strong thin - film coating against peeling off and durable for wiping;
• Double-side coated anti-reflection coating, the light transmission of the parts increased by cylindrical surface polishing, reduction or elimination on stray light of the optical system;
• More bearable for wiping, longer life span as well as better process to radioactive coating.

QUALITY INSPECTION
YONGLI always invests the most reliable measuring equipment to strengthen our quality control capability. Through the years, YONGLI employs quantitative measuring devices for every single production Phase in order to strictly control our products quality no matter components or system level job.
Application
Co2 Laser Focus Lens for all brands of laser cutter & engraver
Widely used in the following brands CO2 laser engraving & cutting machines:Redsail, Kaitian, Yueming, Goldenlaser, Senfeng, Shenhui, York Laser, Hanma Laser, Ruijie, and Bodor etc.
Focal Length Measurement and Cleaning Procedure
How to adjust the focal length
Put a piece of harder paper under the laser head, adjust the height between the laser head and the paper by the focal length ruler, and then press the 'Laser' button on the panel to make marks. Compare the sizes of the marks made in different height and find the minimum sized mark,and then the appropriate height can be determined as the focal length of the machine.The following pictures shows an example. You may see that the mark made in the height of 8 mm is the minimal. Then we know the focal length is 8 mm. In the future, materials with different thickness should be cut in the height of 8 mm.

Notes:
1. Before installing the lens, please confirm the diameter and focal length.
2. The focal length is the distance between the lens and the cutting/engraves material.
3. Suggestion: convex upward, the plane side faces to material.
