Who it fits
Good fit for
This lens suits users with CO2 lasers operating between 150W and 400W. It fits machines that require a 25.4mm diameter focus lens with a 38.1mm focal length. The high transmittance and solid coating benefit operators who need consistent optical performance. It is a practical replacement for worn-out optics. The straightforward design works well for standard engraving and cutting setups. You should verify your machine’s lens size before purchasing.
Who should skip it
Skip this option if your CO2 laser requires a different diameter or focal length. The data lists other sizes like 4" and 7.5", so this specific 25.4mm lens will not fit those systems. It is also unsuitable for lasers outside the 150W-400W power range. If your machine uses a different material or coating type, this lens may not meet your needs. Check your current lens specifications carefully to ensure compatibility.
Verdict: This is a spec-driven replacement lens for compatible CO2 systems. It offers clear optical metrics for users who need a direct fit.
Key specs explained
Diameter: 25.4mm/1"
This measurement defines the physical width of the lens. You must match this size to the mounting holder in your laser machine. A 25.4mm diameter fits standard 1-inch lens holders. If your machine uses a different size, this lens will not fit. Check your current lens or the machine manual to confirm the required diameter before purchasing.
Focal Length: 38.1mm/1.5"
The focal length determines the distance from the lens to the material surface where the laser beam converges. A 38.1mm focal length creates a smaller spot size than longer lenses. This allows for finer detail in engraving and sharper cut lines. You benefit if you need high precision. Longer focal lengths offer a larger depth of field for uneven surfaces.
Transmittance: ≥99.5%
This percentage indicates how much laser energy passes through the lens material. A value of 99.5% or higher means minimal energy loss. More energy reaches the material, resulting in faster cutting and deeper engraving. Lower transmittance wastes power as heat. This spec helps you compare lens quality. Higher numbers generally indicate better optical performance and efficiency.
Material: PVD Znse
Zinc Selenide (ZnSe) is the standard material for CO2 laser lenses. It effectively transmits CO2 laser wavelengths. The PVD coating adds durability and optical precision. This material resists damage from high temperatures and debris. You benefit from a longer lens life and consistent performance. Ensure your laser type is CO2, as ZnSe is not suitable for fiber lasers.
Lens Materials And Physical Build
The listing states the lens uses PVD ZnSe material. This is a standard choice for CO2 laser optics. Zinc selenide transmits CO2 wavelengths efficiently. The coating claims a transmittance of 99.5% or higher. Higher transmittance means less energy loss. Your laser delivers more power to the workpiece. This can improve cutting speed or engraving depth.
The physical dimensions are precise. The diameter is 25.4mm, which equals one inch. The focal length is 38.1mm, or 1.5 inches. The thickness is 3mm. These measurements determine how the lens fits your machine. You need a holder that accepts 1-inch lenses. The focal length sets your working distance. A 38.1mm focal length is common for general engraving and thin cutting.
Weight is listed as 0.1KG or 3.53 ounces. This is a lightweight component. It does not add significant mass to your laser head. The shape is plano-convex. One side is flat, the other is curved. This shape focuses the laser beam to a single point. The listing mentions a solid double-sided coating. This suggests better durability against high temperatures. It is designed for machines using 150W to 400W power. You should verify your machine’s power output matches this range.
Setup and daily operation details
Setting up this lens is a straightforward mechanical task. You replace the existing optical component in your CO2 laser machine. The listing specifies a 25.4mm diameter and a 38.1mm focal length. These dimensions must match your machine’s lens holder. If your engraver uses a standard 1-inch mount, this part fits directly. The lens weighs 0.1kg. This light weight makes handling simple during installation. You handle it carefully to avoid touching the optical surfaces. The physical thickness is 3mm. This dimension ensures it sits correctly in the holder without interfering with the laser path. Daily use depends on matching the lens to your machine’s power. The product supports 150W to 400W CO2 lasers. You must ensure your machine operates within this range. Using it outside these limits may affect performance or damage the coating. The lens features a plano-convex shape. This design focuses the laser beam to a precise point. The double-sided solid coating helps maintain optical clarity. It resists high temperatures generated during cutting or engraving. This resistance contributes to a longer working life. You do not need special software or apps to use it. It is a passive optical component. You simply install it and power on your machine. The package includes one lens. No additional tools or accessories are listed. You rely on your existing machine setup. The high transmittance of 99.5% or more means efficient energy delivery. This efficiency supports consistent cutting and engraving results. You check the fit before powering on. Ensure the lens is clean and secure. Then you proceed with your standard operating procedures. The simplicity of the design means fewer things to go wrong. You focus on your design files and material settings. The lens handles the optical focusing.
Before You Buy This Lens
You need to verify your machine’s lens holder size before ordering. This TEN-HIGH lens has a 25.4mm diameter. It fits standard 1-inch holders. If your device uses a different size, this lens will not work. The focal length is 38.1mm. You must ensure this matches your required focus distance for your material thickness. The listing states compatibility with 150W to 400W power levels. Check your laser’s output power. Using this lens with a machine outside this range may affect performance or safety. You should also have a clean, lint-free cloth for handling. Optical surfaces scratch easily. Proper storage is essential to maintain the 99.5% transmittance claim. This lens is a replacement part, not a complete machine. It belongs in the accessories category for CO2 lasers. Consider your current setup and whether a new focal length offers better engraving depth or cutting speed for your specific materials. Compare this 25.4mm option with the other seven sizes available in the variations list.
Check before you buy
- Confirm your laser machine has a 25.4mm lens holder.
- Verify your machine power is between 150W and 400W.
- Check if a 38.1mm focal length suits your material needs.
- Ensure you have cleaning supplies for optical components.
