Quartz Hexagonal Polished Body

Updated: 2026-08-12

Overview

The quartz hexagonal polished body is a specialized optical component manufactured from synthetic quartz with exceptional purity. Its six precisely polished surfaces enable superior light management in critical applications. The material's inherent properties, including low thermal expansion and high UV transparency, make it indispensable in high-tech industries. Quartz's unique molecular structure provides stability across wide temperature ranges (-200°C to 1100°C), distinguishing it from ordinary glass. The hexagonal shape offers geometric advantages for light manipulation, often serving as prisms or optical windows in advanced systems.

Structure and Working Principle

The component features six optically flat surfaces polished to sub-micron roughness (typically <5nm Ra). Each 120° angle is precision-ground to exacting tolerances (±0.1°). Internal molecular structure remains undisturbed during processing to maintain quartz's isotropic properties. Light interacts with the hexagonal geometry through refraction, reflection, and transmission. The precise angles allow controlled beam deviation while quartz's low dispersion minimizes chromatic aberration. Some variants incorporate anti-reflective coatings to enhance transmission above 99% at specific wavelengths.

Key Features

1. Optical Performance: >90% transmittance from 170nm to 2500nm wavelength range. 2. Thermal Characteristics: Coefficient of thermal expansion 5.5×10⁻⁷/°C (0-300°C). 3. Mechanical Properties: Knoop hardness 480-560, modulus of rupture 50-70 MPa. 4. Chemical Resistance: Inert to most acids except hydrofluoric acid. Manufacturers achieve surface flatness to λ/10 at 632.8nm with scratch-dig specifications of 20-10 or better. The material exhibits minimal birefringence (<5nm/cm), crucial for polarization-sensitive applications. Custom sizes typically range from 5mm to 150mm across flats.

Application Areas

Semiconductor: Used in lithography equipment as optical elements for EUV and DUV light sources. Photonics: Serves as beam splitters in laser systems and optical delay lines. Analytical Instruments: Critical component in spectrophotometer sample compartments and FTIR accessories. Industrial applications include high-temperature viewports for furnace monitoring and UV curing systems. Emerging uses encompass quantum computing optical interfaces and aerospace instrumentation. The medical field employs these components in laser surgery devices and diagnostic equipment.

Maintenance and Precautions

Regular cleaning requires lint-free wipes with isopropyl alcohol or specialized optical cleaners. Avoid abrasive materials that could scratch polished surfaces. For coated variants, use only manufacturer-recommended cleaning solutions. Storage should be in acid-free paper within protective cases, maintaining 20-25°C with <50% humidity. Thermal shocks must be avoided - limit temperature changes to <5°C/minute. During handling, always use powder-free nitrile gloves to prevent contamination from skin oils.

B2B Procurement Guide

Technical specifications should detail: 1. Surface quality (scratch-dig) 2. Wavefront distortion 3. Coating specifications (if applicable) 4. Dimensional tolerances 5. Material certifications (e.g., Corning 7980 equivalent). Lead times typically range 4-12 weeks for custom orders. MOQs vary by supplier but often start at 5-10 units for standard sizes. Quality documentation should include ISO 10110 inspection reports and material traceability certificates. Consider suppliers with cleanroom packaging capabilities for critical applications.
