Frosted Fused Silica Rod 9mm Diameter 23.5mm Length Soft Light Diffusion

The Fused Silica Frosted Rod is a precision optical component with a diameter of 9mm and a length of 23.5mm, manufactured from high-purity silicon dioxide. The uniform fine frosted surface diffuses light softly and evenly, providing stable light scattering performance for spectral and optical systems. With high UV transmittance, excellent temperature resistance and strong chemical inertness, the rod maintains consistent optical behavior in demanding laboratory environments. The durable frosted finish resists peeling, while the ultra-low thermal expansion coefficient and high dimensional accuracy ensure long-term reliability in precision optical assemblies.

• High-purity silicon dioxide material: The fused silica body delivers clean optical performance and reliable consistency.
• Uniform fine frosted layer: The evenly frosted surface scatters light consistently across the full length of the rod.
• Stable soft light diffusion effect: The rod produces smooth, diffuse illumination suitable for optical homogenizing applications.
• High temperature resistance: The material withstands elevated operating temperatures without degradation.
• High UV transmittance: Excellent ultraviolet transmission supports UV spectral and scattering applications.
• Strong chemical inertness: The rod resists chemical attack, keeping its surface and optical properties stable in laboratory service.

The Fused Silica Frosted Rod is designed for optical systems that require controlled light diffusion and scattering. It is widely used as a spectral diffusion accessory, spreading light evenly to improve measurement accuracy in spectrometers and photometers. In illumination systems, the rod serves as an optical homogenizing component, converting point or beam light into uniform diffuse output. The component is also adopted as an optical attenuation part for laboratory optical paths, providing repeatable scattering-based attenuation. Additionally, the rod functions as a scattering rod for standard light sources, helping calibrate instruments by delivering stable, diffused reference illumination.

• Durable frosted surface: The frosted finish is firmly bonded and not easy to peel off during handling and cleaning.
• High dimensional accuracy: Diameter and length are controlled within tight tolerances for consistent optical geometry.
• Ultra-low thermal expansion coefficient: Minimal thermal deformation keeps optical performance stable across temperature changes.
• Corrosion resistance under acid and alkali: The rod remains unaffected in acidic and alkaline environments.
• Consistent optical performance: Uniform material and surface quality deliver repeatable diffusion results from piece to piece.
