Upgrading Precision: Precision Laser Cutting for PNB586 Colored Optical Glass
At YOUJIA OPTICAL, we continuously strive to elevate our manufacturing capabilities to meet the rigorous demands of the global photonics and optoelectronics industries. This month, we are excited to announce a major upgrade to our production line: the integration of a state-of-the-art Laser Cutting System designed specifically for high-precision colored optical glass processing.

The Challenge of Processing PNB586 Optical Glass
PNB586 is a premium phosphate-based colored optical glass, widely utilized in infrared (IR) cut-off filters and specialized spectrum filtering applications. Due to its unique chemical composition, PNB586 is highly sensitive to thermal stress and mechanical impact.
Traditional cutting methods, such as mechanical dicing or diamond wheel cutting, frequently face significant challenges:
- Micro-cracks & Fractures: Mechanical stress can cause sub-surface damage that compromises the structural integrity of the glass.
- Chipping Issues: Edge chipping often requires extensive post-processing (grinding and polishing), increasing lead times and production costs.
- Thermal Stress: Uneven heat distribution during conventional processing can lead to micro-fractures in heat-sensitive substrates.
Our Solution: Advanced Non-Contact Laser Slicing
To overcome these limitations, YOUJIA OPTICAL has deployed an advanced laser cutting system. In our latest production run, this system successfully completed high-density, wafer-level array slicing on PNB586 substrates with outstanding results.
By utilizing optimized laser wavelengths and ultra-short pulse technology, our new process delivers:
- Near-Zero Chipping: The non-contact nature of laser cutting ensures perfectly clean, sharp edges, drastically improving the yield rate for micro-components.
- Ultra-Narrow Kerf Width: Maximizes material utilization, allowing more components to be sliced from a single glass substrate.
- Minimal Heat-Affected Zone (HAZ): Prevents thermal deformation and maintains the precise optical filtering properties of the PNB586 glass.
