High Purity Fused Silica Optical Window for Industrial UV Inspection & Detection Systems

High Purity Fused Silica Optical Window for Industrial UV Inspection & Detection Systems

 

1. Client Equipment Pain Points

 

A US industrial UV detection instrument manufacturer faced unstable detection accuracy caused by low-grade optical windows.

Traditional ordinary glass and low-purity silica substrates cannot transmit short-wave UV light efficiently. Internal impurities and tiny bubbles caused light scattering, resulting in inconsistent UV intensity and fluctuating spectral detection data during industrial material inspection. Low UV transmittance reduced equipment detection sensitivity and caused frequent calibration failures, affecting stable inline quality inspection for factory production lines.

 

2. Material Selection & Technical Comparison

 

Three optical materials were evaluated for industrial UV detection working environments:

 

- BK7 Optical Glass: Extremely poor short-wave UV penetration, unable to support ultraviolet spectral detection, not applicable for UV inspection equipment

- Sapphire Glass: High hardness but uneven UV band transmittance, unsuitable for precise UV spectral analysis and quantitative detection

- Fused Silica Optical Glass: Ultra-high purity material structure, excellent deep UV to visible spectrum transmittance, zero bubbles and impurities, low light scattering rate, stable spectral uniformity — the only qualified material for professional industrial UV detection systems

 

After UV transmittance testing and spectral uniformity comparison, high-purity fused silica was confirmed as the exclusive upgrade solution.

 

3. Customized UV Optical Solution Delivery

 

Felix Glass delivered industrial-grade fused silica UV optical windows customized for the client’s inline UV inspection equipment:

 

- High-purity bubble-free fused silica raw material to eliminate UV light scattering defects

- Double-sided ultra-fine polishing to maximize short-wave UV light transmission efficiency

- Strict internal stress elimination process to ensure long-term spectral stability

- Custom thickness and dimension CNC precision machining to fit UV sensor light path structure

- Cleanroom-level packaging to avoid surface contamination affecting UV detection precision

 

The customized fused silica windows significantly improved UV light utilization rate and stabilized spectral detection repeatability for continuous industrial inspection operations.
