D37 F200 1090nm 12KW Focus Lens Set

d37 f200 focus laser cutting lens set for high-precision fiber laser cutting heads. this germany-material focus lens is designed around 1030–1090 nm fiber laser sources and built to handle up to 12 kw power (when used in a properly maintained cutting head). it conditions and stabilizes the beam before the focus lens, helping you keep a consistent spot size, clean kerfs and repeatable cutting performance in production.

this product is sold as a single focus lens set (1 set per order) each set includes 2 matched lenses **for fiber laser cutting applications.

size:

• lens type: focus lens set for fiber laser cutting
• diameter: d37 mm
• focal length: f200 (focus stage)
• nominal wavelength: 1090 nm (ar/ar 1030–1090 nm coating band)

spec:

• ar/ar coated for 1030–1090 nm fiber laser systems
• rated for up to 12 kw cutting applications (within head and machine limits)
• optimized geometry for f200 mm focus in industrial cutting heads
• designed to deliver a stable, well-shaped beam into the focus lens
• low-reflection coatings to reduce power loss and thermal loading

material:

• high-grade fused silica optics
• low absorption in the 1 µm band to minimize thermal distortion
• durable coating stack for industrial duty cycles and periodic cleaning

use:

• focus lens set for industrial fiber laser cutting machines
• straightens and conditions the laser beam before the focus stage
• supports consistent focus position, clean edges and stable piercing
• suitable for cutting carbon steel, stainless steel, galvanized sheet and similar metals (machine-dependent)

compatibility:

• for cutting heads that use d37 mm, f200 mm focus optics
• typical compatibility: precitec, wsx, bodor, raytools and boci-type fiber laser cutting heads
• always confirm your original lens diameter (37 mm), focus focal length (f200) and mechanical seat before ordering

quality:

• each lens visually inspected for coating quality, surface defects and curvature
• tight control on thickness, flatness and surface quality for repeatable optical performance
• packed in protective foam and a rigid box to keep the optic clean and safe before installation

included:

• 1 × d37 f200 laser cutting focus lens set
• no extra hardware included (reuse existing spacers and mounts from your cutting head)
• each set includes 2 matched lenses
