Fused Silica UV Window for Ultraviolet Testing Instrument

 Fused Silica UV Window for Ultraviolet Testing Instrument

Attention

Conventional soda-lime glass and standard optical glass cannot transmit deep ultraviolet light below 300nm, causing data distortion and low detection accuracy for UV spectrum testing instruments. Ordinary fused silica with impurity defects also suffers poor UV transmittance and light attenuation after long-term irradiation. Our UV-grade synthetic fused silica optical windows deliver stable high transmittance within 185–400nm deep UV band, solving core optical pain points for laboratory ultraviolet testing equipment manufacturers in North America.

1. Unique Deep UV Optical Advantages of UV-Grade Fused Silica

1. Ultra-high transmittance covering 185–400nm deep ultraviolet wavelength, no strong absorption valley for UV testing light source;

2. Low hydroxyl & metal impurity content, no yellowing or light loss under continuous UV radiation;

3. Low thermal expansion coefficient, avoiding focal shift and spectrum drift under long instrument operation;

4. Excellent chemical resistance, stable against lab acid, solvent and ozone aging in UV aging test chambers;

5. High homogeneity, eliminate stray light and ghost image to guarantee accurate spectrum test data.

2. Custom Shapes for All Kinds of UV Testing Equipment

1. Round UV fused silica window: Standard flange matching for UV-Vis spectrophotometer, fluorescence detector;

2. Rectangular fused silica viewport: Compact small UV test chamber, micro sample testing equipment;

3. Custom special-shaped window: Oval, stepped edge, counterbore design for customized lab optical cavity;

4. Vacuum flange pre-assembled window: CF/KF stainless steel flange integrated UV window for high-vacuum deep UV material analysis system.

 3. UV Anti-Reflection Coating & Precision Machining Workflow

Raw UV fused silica blank goes through multi-stage fine grinding, ultra-precision polishing and ultrasonic dust-free cleaning. Custom broadband UV AR coating (185–400nm) can be deposited to raise single-side transmittance over 92%. All components are processed in Class 1000 clean workshop to avoid surface scratch, particle contamination and residual organic pollutants that interfere UV detection results. Edge chamfer, mounting groove and sealing step CNC machining are supported per customer optical drawings.

4. Lab Spectral Transmittance Quality Inspection Standard

Every batch of fused silica UV windows completes full band spectral scanning test. Original lab test curve records real transmittance data from deep UV to visible light, fully matching common deuterium lamp UV light sources. Laser interferometer controls surface flatness up to λ/10 to ensure parallel light transmission and eliminate spectrum deviation during sample testing.

 5. Real Application Case for North American UV Testing Laboratory

A US environmental testing instrument manufacturer replaced common glass viewports with our UV fused silica windows for their water quality UV spectrum analyzer:

1. Deep UV signal loss reduced by 65%, tiny pollutant detection sensitivity greatly improved;

2. Optical component service life extended 6 times, cut frequent replacement and equipment maintenance cost;

3. Stable test data consistency under continuous 24-hour UV aging chamber operation, pass third-party laboratory calibration audit.

 6. Dust-Free Cleanroom Batch OEM Packaging & Delivery

Finished fused silica UV windows are separated into anti-collision dust-free plastic trays, vacuum sealed for cross-border export transportation. Flexible supply chain supports small prototype sample orders and monthly mass bulk production for laboratory instrument OEM factories across North America. Complete English material certification and inspection test reports are attached for import customs clearance and lab audit.

 7. Optical Path Matching Schematic for UV Spectrum Testing System

Complete UV testing optical workflow: Deuterium UV light source → UV fused silica collimating window → Sample testing cavity → Fused silica receiving viewport → Spectrum sensor detector. Our custom fused silica UV window simplifies optical path design for lab equipment R&D engineers and reduces assembly debugging difficulty.
