18 Years Factory Laser Cutting Nozzle Selection - CO2 Laser Optics Lens Manufacturer China – HAAS Detail:

Product Description

CO2 laser cutting can be applied to cut almost all metal or non-metal materials. The optical system includes laser resonator cavity optical system (including rear mirror, output coupler, reflecting mirror and polarization Brewster mirrors) and outside beam delivery optical system( including reflecting mirror for optical beam path deflection, reflecting mirror for all kinds of polarization processing, beam combiner/beam splitter, and focusing lens).

Carmanhaas Focus Lens have two material：CVD ZnSe and PVD ZnSe. Focus lens shape have Meniscus lenses and Plano-convex Lenses. Meniscus lenses are deigned to minimize spherical aberration, producing a minimum focal spot size for incoming collimated light.Plano-convex Lenses, the most economical transmissive focusing elements available,

Carmanhaas ZnSe Focus Lenses are ideally suited for laser head treating, welding, cutting, and infrared radiation collection where spot size or image quality is not critical. They are also the economical choice in high f-number, diffraction limited systems where lens shape has virtually no effect on system performance.

Product Features

(1) High purity, low absorption material (body absorption less than 0.0005/cm-1)
(2) High damage threshold coating (>8000W/cm2)。
(3) Lens focusing reaches diffraction limit
