Precision Custom Optical Prisms from China Suppliers - Right-Angle, Equilateral & Roof Types Available from Factory
●Product Description
Core Functions
- Beam Manipulation: Reflect/refract for beam steering, splitting, polarization control (split ratio 50:50 to 99:1);
- High Dispersion: Equilateral prisms achieve >1.5° dispersion @400–700nm for spectrometers;
- Low Wavefront Distortion: Roof prisms with <3 arcsec 90° tolerance ensure imaging symmetry.
Technical Specifications
- Materials & Design: · UV Fused Silica: >90% transmission @200–2500nm, LIDT >8J/cm² @355nm; · IR Materials (ZnSe, Ge): Covers 3–5μm MWIR for thermal imaging; · Polarizing Beam Splitters (PBS): Extinction ratio >1000:1, LIDT >500mJ/cm² @1064nm.
- Precision: · Surface flatness <λ/5 (@633nm), local figure error <λ/10; · Angular tolerance ±30 arcsec (upgradable to ±5 arcsec); · Surface quality 40-20 scratch/dig (upgradable to 10-5); · Coating reflectivity >99% (metallic) or <0.5% (AR) @target wavelength.
- Coatings: · Metallic (Al, Ag, Au): Broadband reflection (400–2000nm) with environmental resistance; · Dielectric (TiO₂/SiO₂): Laser-grade R>99.8% @specific λ; · Beam-Splitting: Custom polarizing/non-polarizing with <±2% ratio error.
Applications
- Laser Systems: Pulse compression/combining in femtosecond lasers (±0.1ps delay);
- Spectroscopy: Beam splitting in Raman spectrometers (<0.1nm resolution);
- Metrology: Right-angle prisms for interferometers (<λ/20 PV surface);
- Medical Imaging: OCT scanning prisms with <5μm axial resolution.
Customization
- Complex Geometry: D-shape, sector-cut with <0.1mm edge chamfer, holes/threads;
- Multi-Prism Arrays: Cemented/air-spaced assemblies aligned to <1 arcmin;
- Fast Turnaround: Standard orders in 5 days, special requests <3 weeks.
●Differentiation Highlights
Interferometer calibration guarantees ±2 arcsec angular tolerance for ultra-sensitive systems (e.g., gravitational wave detection);
UV-IR composite prisms (e.g., CaF₂/ZnSe) enable cross-band spectral fusion.
