OMTech vs TEN-HIGH CO2 Specs
Laser Type
Both products are designed specifically for CO2 laser systems. The OMTech marking spray is formulated to work with CO2 engravers of 25W and above, as well as fiber lasers, to create high-contrast black marks on metal. The TEN-HIGH focal lens is explicitly listed for CO2 laser cutting and engraving machines. This shared compatibility ensures that either accessory integrates seamlessly into a standard CO2 workflow without requiring different hardware adaptations or incompatible power sources.
Compatible Material
The OMTech spray targets bare metals, including aluminum, stainless steel, and brass, allowing for permanent black designs on jewelry, tumblers, and tools. It is a consumable that modifies the surface appearance of these materials. In contrast, the TEN-HIGH lens is an optical component used within the machine itself. It does not interact directly with the workpiece material but focuses the laser beam to cut or engrave various substrates. One is a material treatment product, while the other is a machine part.
Form Factor
The OMTech item is a 13 fluid ounce aerosol can, measuring 7.9 inches in height and 2.6 inches in width and length. It comes in a 3-pack configuration. The TEN-HIGH lens is a small optical component with a diameter of 0.79 inches and a thickness of approximately 0.09 inches. It weighs only 0.64 ounces. The spray is a bulky consumable package, whereas the lens is a compact, lightweight precision part. Storage and handling requirements differ significantly between the two.
Key Features
OMTech highlights a clog-proof nozzle for even coating, fast drying in under five minutes, and easy washing of excess spray. It uses a cadmium-free formula for safety. TEN-HIGH emphasizes superior transmittance ZnSe material, double-sided solid coating for wiping resistance, and high-temperature laser resistance. The lens features a plano-convex shape for better engraving quality. OMTech focuses on user convenience and finish quality, while TEN-HIGH focuses on optical durability and efficiency.
Build Quality
The OMTech spray relies on its aerosol can construction and nozzle design to deliver a fine-grained agent. The focus is on the consistency of the spray pattern and the chemical stability of the ink. The TEN-HIGH lens is built with high-precision processes, including precision slicing, polishing, and grinding. It uses excellent substrate material to ensure high transmittance and reduce laser loss. The lens construction prioritizes optical clarity and resistance to heat and physical wear over time.
