Focus Lens 1.5 x 5.FL AR .310

The 5mm focal length on this Mitsubishi Focus Lens 1.5 x 5.FL AR .310 produces a tightly concentrated beam spot ideal for thin material processing and intricate cutting patterns. An antireflective coating minimizes energy loss while the shorter focal distance reduces kerf width, making this lens particularly effective for applications where detail and minimal material waste are priorities.

Optimized for Thin Materials and Fine Detail

Shorter focal lengths create smaller beam diameters at the focal point, which translates directly to narrower cuts and reduced thermal distortion in sheet metal under 1/4 inch. The 1.5x magnification paired with the AR coating ensures efficient energy delivery even during high-speed piercing operations. This combination supports faster cycle times on parts requiring tight corner radii or complex geometries.

Operators processing stainless steel, aluminum and mild steel in thinner gauges benefit from the reduced heat-affected zone this focal length provides. Alternative Parts, Inc. (API) verifies dimensional conformity on every lens through our quality control process, ensuring compatibility with Mitsubishi laser heads and consistent optical characteristics across production batches.
