Available Upper Protective Lens Sizes
This collection includes BOCHU BOCI upper protective lenses for BLT fiber laser cutting heads. Available configurations include D21.5 × 2 mm, D25.4 × 4 mm and D36 × 5 mm windows, with different power ranges and model-specific BOCHU part numbers. These lenses protect the internal optical assembly from dust and contamination.
How to Select an Upper Protective Lens
Match the diameter, thickness, upper-window position, laser power range and original part number shown on the existing package. Protective lenses with similar diameters may use different thicknesses or applications. Provide a photo of the lens label or cutting-head nameplate when the correct specification is uncertain.
