Optical Specs and Power Range
Compatible Laser Power
The TEN-HIGH 30mm Gold-Plated Copper CO2 Mirrors support a broad power range from 40W to 5000W. This makes them suitable for high-power industrial applications where heat dissipation is critical. In contrast, the TEN-HIGH 25.4mm ZnSe CO2 Focus Lens is rated for 150W to 400W. This narrower range targets standard desktop and small studio engravers. If you run a high-power system above 400W, the copper mirror is the only viable option. For lower power setups, both components function correctly, but the ZnSe lens is optimized for that specific bracket.
Optical Material and Type
Product A uses gold-plated oxygen-free copper, which is a reflective material. It is designed to reflect the laser beam rather than transmit it. Product B uses PVD ZnSe, a transmissive material that allows the laser to pass through. The copper mirror has a plane shape, while the ZnSe lens is plano-convex. This fundamental difference means they serve different roles in the optical path. You cannot swap them directly. The ZnSe lens focuses the beam to a point, whereas the copper mirror directs it. Your machine design dictates which material you need.
Diameter and Size
The gold-plated copper mirror has a diameter of 30mm, or approximately 1.18 inches. The ZnSe focus lens has a diameter of 25.4mm, which is exactly 1 inch. Both components share the same thickness of 3mm. The larger diameter of the copper mirror may offer more flexibility in mounting configurations for larger optical benches. The smaller diameter of the ZnSe lens is standard for many compact CO2 laser heads. If your mounting hardware is sized for a 1-inch lens, the copper mirror might require an adapter. Check your machine's optical tube dimensions before purchasing either part.
Transmittance and Coating
Both products feature high-efficiency coatings to minimize energy loss. The gold-plated copper mirror boasts a transmittance of greater than 99.9%. The ZnSe focus lens offers a transmittance of at least 99.5%. While both are excellent, the copper mirror has a slight edge in optical efficiency according to the specifications. Both items undergo precision slicing, polishing, and grinding. The ZnSe lens features a double-sided solid coating. The copper mirror relies on its gold plating for performance. Higher transmittance means more laser power reaches the material, potentially improving cut quality or speed.
Focal Length and Shape
The ZnSe focus lens has a defined focal length of 38.1mm, or 1.5 inches. Its plano-convex shape is designed to converge the laser beam to a specific point for engraving or cutting. The gold-plated copper mirror has a plane shape and does not have a focal length listed. Reflective mirrors do not focus light in the same way transmissive lenses do. They redirect the beam path. If you need to change the focal spot size, the ZnSe lens is the variable component. The mirror simply maintains the beam's trajectory. This distinction is crucial for optical alignment.
Choose the Right Optical Component
High-power industrial engraving users
If your machine operates between 40W and 5000W, this gold-plated copper mirror is the correct choice. Its broad power compatibility handles high heat better than standard lenses. The 30mm diameter and plane shape direct the beam effectively for large-format cutting tasks where thermal management matters most.
Standard CO2 laser engravers
For machines running 150W to 400W, this ZnSe focus lens provides the necessary focal length of 38.1mm. The plano-convex shape concentrates the beam for precise engraving and fine cutting. Its 25.4mm diameter fits standard optical tubes, making it the practical upgrade for most desktop and hobbyist systems.
Users needing beam redirection
This component acts as a mirror, not a lens. It reflects the laser beam rather than focusing it. If you need to guide the beam path within your machine chassis or direct light to a different angle, this gold-plated copper mirror is the essential optical element for your CO2 laser setup.

Frequently asked questions
Is the 30mm gold-plated copper mirror better for high-power CO2 lasers?
Yes, the TEN-HIGH 30mm gold-plated copper mirror is designed for high-power setups. It supports a power range from 40W to 5000W. This broad compatibility handles high heat effectively. It is ideal for demanding industrial engraving work where standard lenses might struggle with thermal load.
What is the size of the TEN-HIGH ZnSe focus lens?
The TEN-HIGH ZnSe focus lens has a size specification of 1.5 inches, which equals 38.1mm. It weighs 3.53 ounces. This size makes it a standard replacement for many CO2 laser machines, particularly those operating between 150W and 400W.
Can the gold-plated copper mirror replace a standard focus lens?
No, these components serve different functions. The gold-plated copper mirror is a reflective optic used to direct the laser beam. The ZnSe lens is a transmissive optic used to focus the beam. They are not interchangeable due to their distinct optical properties and mounting requirements.
Which lens is suitable for machines under 150W?
The TEN-HIGH ZnSe CO2 focus lens is suitable for standard machines. It is rated for systems from 150W to 400W. While the gold-plated mirror supports lower powers down to 40W, the ZnSe lens is the standard choice for typical engraving and cutting tasks in this range.
Does the copper mirror have a specific diameter?
Yes, the TEN-HIGH gold-plated copper mirror has a diameter of 30mm. This specific size is crucial for compatibility with certain laser tube assemblies. Ensure your machine accepts a 30mm optic before purchasing, as it differs from the 25.4mm or 38.1mm sizes used by other components.
Is the ZnSe lens made of gold-plated copper?
No, the ZnSe lens is made of Zinc Selenide, not copper. The product data identifies it as a standard CO2 laser lens. The gold-plated copper component is a separate mirror product. They use different materials to manage heat and transmit or reflect laser light.
