FOCUSING LENS D30F200

About FOCUSING LENS D30F200

The D30 F200 focusing lens is a high-precision optical lens used in fiber laser cutting heads to concentrate the laser beam onto the material surface for accurate and efficient cutting. With a 30 mm diameter and 200 mm focal length, this lens provides stable beam focusing and excellent cutting performance in industrial laser cutting machines.

Product Description

The D30 F200 focusing lens is manufactured from high-purity fused silica (optical quartz) and coated with advanced double-sided anti-reflective (AR) coating. This coating ensures high laser transmission, low energy loss, and strong resistance to high temperatures during continuous cutting operations.

Its longer 200 mm focal length helps produce a stable focal spot and deeper cutting capability, making it ideal for processing thicker metal materials with consistent edge quality.
