Product Description

General Introduction: Barium Fluoride(BaF2)
Hellma Materials Barium Fluoride is the material of choice for wide bandwidth applications covering the VIS, near-IR and mid-IR range. It is an optical crystal grown from highly purified synthetic raw material and features a superior internal transmittance (T > 99% @7μm) enabling advanced applications in thermal imaging, night vision and surveillance imaging using integrated VIS and IR detector channels. Low spectral dispersion makes BaF2 the preferred optical material for aberration and color correction.
Barium Fluoride is widely used in VIS/IR applications.

Alias: Barium Fluoride(BaF2), Barium Fluoride, Barium Fluoride VIS, Barium Fluoride IR, Hellma Barium Fluoride, Barium Fluoride Windows, Hellma BaF2, hellma BaF2, Barium Fluoride optical materials, BaF2 optical materials, etc.

Main Characteristics:
Same to Calcium Fluoride, Hellma Materials large size Barium Fluoride crystals does specifically meet the requirements of astronomical optical instrumentation, It has the following main characteristics:
1). Featuring a consistently high transmittance covering the full spectrum of ultraviolet, visible and infrared wavelengths.
2). Low spectral dispersion makes BaF2 the preferred optical materials for aberration and color correction.
3). Critical optical parameters including high refractive index homogeneity and low stress birefringence enable high performance optical designs for the full range from next generation ground-based extremely large telescopes (ELTs) to portable refractors for semi-professional use.
4).High resistance of BaF2 against Gamma radiation exposure proven by transmission testing makes these materials a superior choice also for space borne optical instruments.
