Transparent Quartz Prism Quartz Glass Crystal Customized by Drawings
Quartz prisms are spectroscopic or refractive optical components precision-fabricated from high-purity fused silica (SiO₂≥99.99%) through cold working processes. They exhibit exceptional optical homogeneity (Δn≤±5×10⁻⁶) and broad-spectrum transmission (170nm-2500nm), with a low thermal expansion coefficient (0.55×10⁻⁶/°C) and high laser damage resistance (LIDT>10J/cm²@1064nm), making them ideal for laser systems, spectrometers, and UV optical devices.
ZMSH specializes in manufacturing high-precision optical components, offering customized design, precision machining, and coating services for quartz prisms. We support client-provided drawings for custom orders, including right-angle, equilateral, and beam-splitting prisms, achieving micron-level surface accuracy (λ/10@632.8nm) and ultra-smooth finishes (Ra≤0.5nm).

Key features of quartz prism
The core advantages of quartz prisms include:
- Broad-Spectrum Transmission: High transmittance from UV to IR (UV>85%@200nm, visible>93%@550nm) for multi-band optical systems.
- Thermal Stability: Withstands temperatures up to 1000°C with minimal thermal drift.
- Chemical Inertness: Resistant to acids/alkalis (except HF), suitable for harsh environments.
- High LIDT: Superior to conventional optical glass for high-power laser applications.
- Precision Machining: Angular tolerance within ±3 arcsec and surface roughness ≤0.5nm.
Primary applications of quartz prism
Quartz prisms are widely used in:
- Laser Technology: Tuning prisms or beam expanders in laser cavities requiring high damage resistance.
- Spectroscopy: Dispersion elements in spectrometers demanding high homogeneity and low stray light.
- UV Optics: Beam-steering prisms for UV lasers reliant on deep-UV transmission.
- Research Instruments: Refractive/dispersive components in interferometers/telescopes needing sub-micron surface accuracy.
- Industrial Inspection: Alignment prisms in wafer inspection tools, tolerant to high temperatures and contamination-free.

Q&A
1. Q: What is a quartz prism?
A: A quartz prism is an optical component made from high-purity fused silica, designed for precision light refraction/dispersion with superior UV-IR transmission and thermal stability.
2. Q: What is the difference between glass prism and quartz prism?
A: Key difference: Quartz prisms outperform glass in UV transmission (down to 170nm), thermal resistance (up to 1000°C), and laser damage threshold, while glass prisms are typically cheaper but limited to visible light applications.
