D38 ET2 Protective Window 6 kW for Fiber Laser Cutting Heads (10 pcs)

d38 × et2 mm protective window for fiber laser cutting heads rated up to 6 kw. the fused silica window takes the spatter, fumes and dust from the cut so the focusing optics behind it stay clean.

size:

• diameter (d): 38 mm
• thickness (et): 2 mm
• pack: 10 × protective window

spec:

• ar-coated for fiber laser wavelengths to reduce reflection and power loss
• power rating: up to 6 kw in a clean, correctly aligned cutting head
• thin 2 mm profile for heads designed around thin windows
• parallel, flat faces keep focal position and beam quality stable

material:

• fused silica (quartz) optical glass
• low absorption at fiber laser wavelengths, limiting thermal lensing
• durable ar coating on both faces

use:

• protective window in fiber laser cutting heads
• shields the focus lens from dust, fumes and metal spatter
• extends focus lens life and reduces unplanned cleaning stops

compatibility:

• for fiber laser cutting heads that use round d38 mm × et2 mm protective windows
• always confirm your original window diameter and thickness before ordering
