Barium Fluoride Optical Prism

Barium fluoride (BaF₂) is a high-performance optical crystal material covering the broad spectrum from deep ultraviolet to mid-infrared. Its extremely broad transmission band, ultralow dispersion, high optical homogeneity, and excellent physical and chemical stability make it ideal for prisms in ultraviolet/infrared dual-band optical systems, medical optics, infrared detection, spectroscopy, and research experiments. Scysgx uses high-purity barium fluoride single-crystal substrates and more than 260 precision processing machines and 65 specialized inspection instruments to provide a complete closed-loop production line covering cutting, grinding, polishing, coating, and quality inspection. Barium fluoride optical prisms are available as right-angle, Dove, pentagonal, roof, beamsplitting, polarizing, and custom prisms, with side dimensions of 1–1000mm and hypotenuse dimensions of 1–600mm. Commercial-grade and high-precision options offer flatness up to λ/10. Antireflection, high-reflection, polarizing, beamsplitting, and other specialized coatings are available, providing highly precise, stable prism solutions for broadband optical systems. Some standard specifications are stocked long term for rapid delivery.

Multiple coatings: antireflection, high reflection, filtering, polarization, beam splitting, DLC diamond-like carbon and high-laser-damage-threshold coatings support multifunction systems. Excellent physicochemical stability: heat/radiation resistance, chemical inertness, stable, drift-free long-term performance in harsh industrial, medical and research environments. Two grades: commercial for general industry and high precision for research/medical applications, balancing performance and cost. IV. Core material advantages. Spectral coverage: high broadband transmission over 200nm (deep UV)–14000nm (mid-IR), a preferred dual-band material without significant absorption or scattering. Optical properties: refractive index n_d=1.475, Abbe number Vd=81.6, ultralow dispersion, high contrast and easily corrected aberrations for precision broadband beam splitting and imaging. Physical properties: density 4.89g/cm³, Knoop hardness 82 and moderate mechanical strength enable ultraprecision polishing and irregular structures for diverse prism designs. Thermal properties: expansion coefficient 18.1×10⁻⁶/℃, softening temperature 800℃, excellent heat resistance and thermal stability, without significant optical deterioration under temperature fluctuations. Application advantages: outstanding radiation resistance for medical optics, aerospace optics and research spectroscopy, without long-term performance drift. V. Structures and customization. 1. Standard prisms: right-angle, Dove, pentagonal, roof, beamsplitter, polarizing, rhomboid and corner-cube prisms. 2. Customization: side/hypotenuse dimensions and optimized tolerance grades fit optical-system space; special-angle and irregular prisms can have arbitrary angles to suit optical-path designs; chamfering, edge grinding, ultraclean polishing and custom cleaning meet cleanroom/special-environment requirements; band- and function-specific antireflection, high-reflection, polarization and beamsplitter coatings improve performance. VI. Standard coatings. Deep-UV/UV AR: dedicated 0.28–3μm antireflection improves deep-UV transmission and reduces reflection loss. Near-/mid-IR AR: 8–12μm and 2–14μm for infrared optics and lasers. Broadband AR: full-band 200nm–14μm for UV/IR dual-band systems. Polarization/beamsplitter coatings: PBS polarizing and NPBS nonpolarizing beamsplitter layers for polarization and beam-splitting optical paths. High-laser-damage-threshold coatings improve strong-laser tolerance and protect core optics in high-power UV/IR systems. Other coatings: high reflection, filtering and DLC for multifunction optics. VIII. Yasi Optical advantages. Fully controlled in-house closed-loop blank cutting, milling/grinding, polishing, angle machining, coating, inspection, cleaning and packaging, without outsourcing and with full traceability. Precision equipment: ZYGO interferometers, precision goniometers, optical dimensional measuring instruments and surface-quality testers control all parameters and ensure flatness, angular tolerance and transmission compliance. Large/irregular fabrication: batch production of 1–1000mm large-aperture prisms and custom irregular/special-angle prisms meet high-end optical-path design needs. One-stop customization: structure, dimensions, angles, tolerances and coatings, with optical-path adaptation support and dedicated nonstandard solutions. Two-grade delivery: commercial/high-precision grades and stable small/large batches for general industry and advanced research/medical use. Stock/delivery: some standard products remain stocked for rapid delivery; controlled custom-order lead times meet schedules. IX. Quality assurance. All barium fluoride prisms undergo ZYGO interferometric flatness, precision-goniometer angle, optical dimensional, spectral transmission and surface-quality inspections to ensure 100% compliance. Automated ultrasonic ultraclean washing and vacuum moisture-proof packaging ensure transport and long-term stability for cleanrooms and harsh environments.
