High Uniformity Fused Silica Optical Blank & Window for Laboratory UV Testing Systems

High Uniformity Fused Silica Optical Blank & Window for Laboratory UV Testing Systems

 

1. Client Equipment Pain Points

 

A US laboratory instrument supplier developing UV spectral testing devices faced consistent performance flaws with standard optical blanks.

Conventional low-purity glass substrates contained internal impurities and micro-scratches, which caused uneven UV light transmittance and distorted spectral test data. Cheap optical blanks required frequent replacement after short lab usage cycles, raising university and industrial lab operating costs. The client required long-life, high-uniformity optical blanks that deliver stable UV transmission for daily laboratory spectral analysis work.

 

2. Material Selection & Technical Comparison

 

Three optical materials were tested for continuous laboratory UV testing environments:

 

- BK7 Optical Glass: Poor UV light penetration, cannot support short-wave UV spectral testing, unsuitable for lab UV inspection equipment

- Single Crystal Sapphire: High hardness but limited UV transmission range, and birefringence interferes with standard UV spectral detection data

- Fused Silica Optical Glass: Ultra-high purity raw material, full deep UV to visible spectrum transmittance, zero birefringence, excellent internal uniformity, ideal for long-cycle laboratory UV testing instruments

 

After UV transmittance and long-term aging simulation testing, high-purity fused silica optical blanks were confirmed as the standard laboratory solution.

 

3. Customized Laboratory Optical Solution Delivery

 

Felix Glass provided custom lab-grade fused silica optical blanks matching the client’s UV test equipment light path structure:

 

- Low-impurity high-purity fused silica ingot raw material to eliminate UV light blocking defects

- Double-sided fine polishing to remove surface scratches and guarantee uniform light transmission

- Stress-relief thermal annealing to avoid internal light path distortion

- Custom thickness & dimension CNC machining to fit standard lab test fixture mounts

- Strict batch consistency control for mass laboratory instrument assembly

 

The customized fused silica blanks eliminated spectral data deviation and extended service life for daily laboratory UV testing workflows.
