How alternatives compare to Cloudray
DGHUNST 100W CO2 Laser Power Supply
The DGHUNST 100W CO2 Laser Power Supply serves a different component role than the Cloudray tube. While the Cloudray unit provides the 40W laser source itself, this power supply manages the high voltage for tubes ranging from 80W to 120W. You would not swap the Cloudray tube for this item unless you are upgrading to a higher power system. The DGHUNST unit measures 11.2 inches in length and 7.68 inches in width. It offers a compact design suitable for systems with limited space. This choice is for users who already have a compatible high-power tube and need a replacement power source rather than a new laser emitter.
XUNKUANER 210x210mm CO2 F-Theta Lens
The XUNKUANER 210x210mm CO2 F-Theta Lens addresses marking precision rather than raw power output. Unlike the Cloudray tube which generates the laser beam, this lens focuses that beam for galvo systems. It provides a large 210x210mm marking field, which is significantly wider than standard engraving areas. The lens weighs 6.4 ounces and measures 5.5 inches in length. It is designed for CO2 galvo setups requiring consistent results on metals. You should choose this alternative if you are upgrading a marking system to handle larger fields. It does not replace the laser tube but enhances the output of an existing one.
TEN-HIGH Aluminum Honeycomb Table 430x330mm
The TEN-HIGH Aluminum Honeycomb Table is a structural accessory, not a laser component. It measures 430x330mm and provides a durable base for CO2 engravers. The Cloudray tube generates the beam, while this table supports the material being engraved. The honeycomb design promotes airflow to prevent smoke marks on materials. It is a practical addition for users needing a stable, flat surface. You would add this to your setup alongside the Cloudray tube. It does not affect laser power or wavelength. This item is for users who need to replace or upgrade their workbed rather than the laser source itself.
TEN-HIGH 40W CO2 Glass Laser Tube
The TEN-HIGH 40W CO2 Glass Laser Tube is the closest direct alternative to the Cloudray model. Both provide 40W of laser power. However, the TEN-HIGH tube is 700mm long, which is 20mm shorter than the 720mm Cloudray tube. The TEN-HIGH width is 1.97 inches, similar to the Cloudray. The Cloudray tube features pre-connected ports for easier installation. The TEN-HIGH option offers a transparent glass design. You should pick the TEN-HIGH tube only if your machine has a 700mm slot. The 20mm length difference means it will not fit machines designed for the longer Cloudray 720mm tube.
TEN-HIGH 5" Focal Lens for CO2
The TEN-HIGH 5" Focal Lens is an optical component, not a power source. It has a 127mm focal length and weighs 3.53 ounces. The lens measures 1.97 inches in length and width. It delivers high transmittance and durable coatings for precise CO2 laser work. This item focuses the beam generated by a tube like the Cloudray. It does not produce laser light itself. You would use this lens with the Cloudray tube to improve cut quality or engraving detail. It is a necessary upgrade for users needing a specific focal length. It complements the tube rather than replacing it as a primary laser source.
TEN-HIGH CO2 Laser Machine USB Key
The TEN-HIGH CO2 Laser Machine USB Key is a software license, not hardware. It unlocks compatible CO2 laser systems for standard or upgrade versions. The Cloudray tube is a physical glass component that emits laser light. The USB key provides no engraving capability on its own. It is a necessary accessory for users who already own a compatible machine. You would need this key to operate the machine, but it does not replace the laser tube. This item is for users who have a compatible system but lack the required license key. It is unrelated to laser power, tube length, or optical quality.
