Customized Quartz Optical Glass Prism UV-Grade Fused Silica Right Angle Prism

Customized Quartz Optical Glass Prism UV-Grade Fused Silica Right Angle Prism

Quartz prisms are optical components manufactured from high-purity fused silica (silicon dioxide, SiO₂ ≥99.999%) through precision grinding, polishing, and coating processes. They exhibit ​​extreme thermal stability​​ (-200°C to 1100°C), ​​low thermal expansion coefficient​​ (5.5×10⁻⁷/°C), and ​​UV to IR full-spectrum transmittance​​ (185–3500 nm). Core advantages include:

· ​​Chemical inertness​​: Resistant to strong acids (except HF), alkalis, and organic solvents, suitable for corrosive environments.

· ​​Optical precision​​: Surface figure accuracy λ/10@632.8nm, angular tolerance ±3 arcseconds.

· ​​Diverse shapes​​: Right-angle, pentagonal, Dove, and roof prisms, supporting customized functions such as beam splitting, imaging, and light path deflection.

​​ZMSH​​ specializes in custom-manufactured quartz prisms, offering end-to-end services from design to mass production. Our products serve industries including fiber optics, laser systems, and semiconductor manufacturing, with support for drawings-based customization and small-batch rapid delivery (e.g., dimensions: 3–72.5 mm edge length, 0.1–5 mm thickness).

Key features of quartz prism

1. Material Properties

​

​​- High purity​​: SiO₂ ≥99.999%, impurities <5 ppm, ensuring low UV absorption (>90% transmittance at 200 nm).

​​- High-temperature resistance​​: Short-term tolerance up to 1200°C, long-term operational stability at 800–1000°C. Thermal expansion coefficient is 1/10th of standard glass.

2. ​​Optical Performance​

- ​​Transmittance​​: ≥90% (UV: 185 nm), ≥95% (visible), ≥85% (IR: 3500 nm).

- ​​Low dispersion​​: Abbe number >65, minimizing spectral broadening for high-precision applications.

3. ​​Mechanical Properties​​

- ​​Compressive strength​​: >1000 MPa, resistant to mechanical shock.

- ​​Lightweight​​: Density 2.2 g/cm³, 15% lighter than K9 glass.

4. ​​Surface Treatments

​​

​​- Coating options​​: Anti-reflective coating (AR, R<0.5%@400–1600 nm), reflective coatings (Al/Ag, R>95%), and laser damage-resistant coatings.

​​- Edge design​​: <0.2×45° protective chamfer to reduce stress concentration.

5. ​​Shape Diversity​​

- Right-angle prism​​: Light path deflection of 90° or 180°, used in periscopes and autocollimators.

​​- Pentagonal prism​​: Image deflection by 90° without rotation, ideal for laser rangefinders.

​​- Dove prism​​: Doubles the rotation angle of the incident light, suitable for panoramic viewing systems.

- ​​Roof prism​​: Folds light paths by 90° while inverting images, commonly used in telescopes.

Primary applications of quartz prism

1. Optical Instruments​​

· ​​Spectroscopy​​: Dispersive elements in spectrophotometers and Raman spectrometers.

· ​​Imaging systems​​: Translating prisms in microscopes and telescopes (e.g., Dove prisms).

2. ​​Laser Technology​​

· ​​Beam control​​: Laser resonators and rangefinder beam steering (pentagonal prisms).

· ​​High-power applications​​: Withstand 10⁶ W/cm² laser intensity for cutting/welding systems.

3. ​​Semiconductor Manufacturing​​

· ​​Wafer inspection​​: Photolithography equipment alignment prisms.

​​· Packaging testing​​: Infrared thermal imaging window prisms.

4. ​​Medical Devices​​

· ​​Endoscopic imaging​​: Steering prisms in medical fiber optics.

· ​​Laser therapy​​: Precision light path guidance in ophthalmic surgeries.

5. ​​Research & Industry​​

· ​​Quantum communication​​: Light path folding in single-photon detectors.

​​· Aerospace​​: UV imaging prisms in satellite remote sensing.

ZMSH's Services

ZMSH focuses on deep customization of quartz prisms, offering end-to-end services from optical design to mass production. Clients may specify materials (e.g., JGS1 UV-grade fused silica), dimensions (3–72.5 mm edge length), angular tolerances (±3 arcseconds), and functional requirements (e.g., laser damage-resistant coatings, gradient refractive index). We support non-standard shapes (e.g., spiral, bifurcated) and hybrid material composites (quartz-metal bonding).
