protective window d24.4mm et2mm 1090 nm for precitec procutter 2.0 fiber laser up to 20kw - germany material

d24.4 et2 protective window for high-power high-duty fiber laser cutting heads. high-duty germany material protective window made from fused silica with ar coating around 1090 nm and rated for up to 20 kw when used in a properly maintained head. this optic sits in front of the focus lens and takes the hit from spatter, fumes and dust so your main optics stay clean longer. suitable for precitec procutter 2.0 fiber laser cutting head applications where stable optical protection and consistent cutting performance are important.

size:

• diameter (d): 24.4 mm

• thickness (et): 2 mm

• quantity: 1 × protective window

spec:

• optimized for ~1090 nm fiber laser systems

• ar-coated surfaces to reduce reflection and power loss

• power handling: up to 20 kw in a correctly aligned and maintained cutting head

• precise thickness and surface flatness for stable cutting performance

• parallel faces to help maintain consistent focus and gas flow

material:

• quartz fused silica – “germany material” optics

• low absorption and good thermal stability under high power

• durable ar coating for long service life

use:

• protective front window in fiber laser cutting heads

• shields the focus lens from dust, fumes and metal spatter

• helps extend focus-lens lifetime and reduce unplanned downtime and cleaning stops

compatibility:

• for precitec procutter 2.0 fiber laser cutting heads that use round protective windows at d24.4 mm / et2 mm

• suitable for procutter 2.0 type cutting head maintenance and replacement needs

• always confirm your original window’s diameter and thickness before ordering

quality:

• each window visually inspected and packed in clean trays
