Focus Lens Protectors for CO2 and YAG Lasers

The focus lens protector from REFLEX Analytical Corporation is a precision fabricated optic for CO2 and YAG lasers. The lens protector establishes nobility as a focus lens shield against airborne particles (back spatter, fumes) and the variety of contaminants surrounding the work area.

"It is a cost-effective solution engineered to maximize the productive life of a focus lens within a laser system designed for cutting, welding or laser engraving," said a company spokesperson. "The lens protector is a value-added benefit for laser operators, who are particularly pleased with the savings lens protectors can offer since the damage and replacement of focus lenses is reduced significantly."

The CO2 laser lens protector is fabricated from either potassium chloride (KCl) or zinc selenide (ZnSe). The KCl lens protector is a cost-effective material solution engineered to maximize the productive life of a ZnSe focus lens within a CO2 laser system designed for cutting, welding or laser engraving at 10.6 micron. The ZnSe lens protector offers material advantages of greater hardness, strength and durability and includes an optional performance-enhancing anti-reflection coating that provides high laser energy throughput at 10.6 micron.

The YAG laser lens protector is fabricated from high purity specialty quartz. "It is a low absorption material engineered to minimize heating and its extremely low coefficient of thermal expansion results in an excellent thermal shock resistance that is superior to ordinary glasses," said the spokesperson. To further enhance performance, a high damage threshold anti-reflection coating is applied to provide for high energy throughput for 1030nm, 1064nm and 1070nm CW and pulsed lasers.

Most lens mounts are designed to provide adequate space for the insertion of a plano-plano lens protector in front of the focusing lens. REFLEX suggests confirming the available space within the focus lens mount or laser head since there is variation depending upon the laser manufacturer and the focus lens edge thickness. Lens protectors can be supplied as thin as 2 mm. The diameter of the lens protector would be the same as the focus lens diameter.

The lens protector materials processed satisfy strict quality control standards which meet or exceed the performance requirements of the laser system manufacturer. Custom components are available upon request. A representative list of laser systems supported, but not limited to, includes: Amada, Bystronic, Cincinnati, Coherent, Convergent Energy, Epilog, Kodak, Lasercamm, Laser Cut, Laser Lab, Mazak, Mitsubishi, PRC Laser, Rofin-Sinar, Strip-It, Synrad, Trumpf, Universal and others.
