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
Sub-Arcsecond Precision
Interferometer calibration guarantees ±2 arcsec angular tolerance for ultra-sensitive systems (e.g., gravitational wave detection).
Hybrid Material Design
UV-IR composite prisms (e.g., CaF₂/ZnSe) enable cross-band spectral fusion.
