CO₂ Optical Field Lens
CO₂ Optical Field Lens
Products Description
CO₂ optical field lens, sometimes referred to as an F-theta lens or a flat field lens, is an essential component in CO₂ laser marking or engraving systems. These lenses are specifically designed for CO₂ lasers with a wavelength of around 10.6 micrometers and made from a material like ZnSe, which is transparent to infrared radiation.
The primary function of a CO₂ optical field lens is to focus the laser beam precisely onto the workpiece or substrate being engraved or marked. The lens effectively linearizes the radial scanning motion of the galvanometer scanner, creating a flat field over the entire scan area. This ensures a uniform focus and spot size across the marking field, improving the quality and consistency of the end result.
Focal length: Lenses with different focal lengths create different working distances and marking areas. Based on your application, choose a lens with a proper focal length that meets your marking or engraving requirements.
Material: The lens should be made of a material compatible with CO₂ lasers, like ZnSe, which has excellent transmission properties in the 10.6 μm wavelength range.
Coating: Make sure that the lens is coated with an anti-reflective coating to minimize reflections and maximize power transmission.
Diameter: The diameter of the lens should be large enough to accommodate the maximum laser beam size in your application. Bigger diameter lenses have higher damage thresholds and provide a larger field of view.
Quality: Ensure the lens quality by considering factors like surface accuracy, uniformity, and minimal wavefront distortion for precise, high-quality marking or engraving.
By carefully selecting the right CO₂ optical field lens for your application, you can achieve optimal laser marking or engraving efficiency, precision, and consistency.
CO₂ Optical Field Lens is easy to operate, energy efficient, customizable and has a long life span. It has good face shape precision, with high precision mounting and calibration, and can respond quickly. It can be used for all kinds CO₂ tube, and the working area is based on the focal length. Monolithic flat field scan lens is designed for CO₂ laser scanning system, widely used in drilling and marking fields.
Features
CO₂ Optical Field Lens is commonly used in laser engraving, cutting, marking systems, etc. For lightly contaminated dust, perform abrasive cleaning with a particulate needle and use a blowing airbag to blow off any contaminants scattered on the surface of the optics. It is also called flat field focusing mirror, scanning lens, mainly used to focus the light coming out of the oscillator on a plane.
