Laser Cutting Machine Protective Lens D38×1.6mm D38×1.5mm
The D38.1×1.6mm protective lens is a high-precision optical consumable engineered for fiber laser cutting heads operating in medium- to high-power ranges. Built from premium fused silica and coated for low reflectivity, it shields the internal optical path from dust, spatter, fumes, and thermal impact, ensuring stable cutting performance and long service life. This protective lens is essential for maintaining clean transmission and preventing contamination in industrial metal-cutting environments.
Features
- 38.1mm diameter × 1.6mm thickness; lightweight and high-transmission design
- High-purity fused silica with excellent thermal and mechanical stability
- Double-sided anti-reflection coating for reduced energy loss
- Durable anti-spatter and anti-dust surface treatment
- Designed for continuous, high-duty metal cutting operations
Advantages
- Protects focus lens and internal optics from metal debris and smoke
- Enhances cutting consistency and edge quality
- Extends optical component lifespan and reduces maintenance cost
- Supports stable performance under long production cycles
- Improves system uptime and lowers consumable replacement frequency
