Product Description Product DescriptionHellma Materials Barium Fluoride (BaF2) is a high-performance optical crystal engineered for wide bandwidth applications spanning the VIS, near-IR, and mid-IR spectral ranges. Grown from highly purified synthetic raw materials, it delivers superior internal transmittance (T > 99% @ 7μm), making it ideal for advanced thermal imaging, night vision, and surveillance imaging systems with integrated VIS and IR detector channels. Its low spectral dispersion also positions it as the preferred material for aberration and color correction in optical designs.Broad Spectral Transmittance: Maintains consistently high transmittance across UV, VIS, and IR wavelengths, supporting multi-band optical applications.Low Spectral Dispersion: Enables precise aberration and color correction, enhancing optical system accuracy.Superior Optical Homogeneity: Features high refractive index uniformity and low stress birefringence, suitable for high-performance designs from large telescopes to portable refractors.Gamma Radiation Resistance: Proven resistance to gamma radiation (validated by transmission testing), ideal for space-borne optical instruments. Application ScenariosThermal imaging, night vision, and surveillance imaging systemsAstronomical optical instrumentation (ground-based ELTs, semi-professional refractors)Space-borne optical equipment and radiation-resistant applicationsVIS/IR integrated optical devices requiring color correctionHigh-precision optical systems for industrial and scientific research Customization services for dimensions, coatings, and specifications are available.
