ISP Optics Calcium Fluoride (CaF2) Wedged Windows feature a 30 arcmin wedge to eliminate fringe patterns from etalon effects and to prevent cavity feedback. Calcium fluoride’s combination of low absorption and high damage threshold make these windows a popular choice for free-space lasers. Its low refractive index allows it to be used without an anti-reflective coating. ISP Optics Calcium Fluoride (CaF2) Wedged Windows feature low water solubility and offer superior hardness compared to other fluoride-based substrates, making them suitable for laser applications in harsh environments. Calcium Fluoride (CaF2) Wedged Windows provide laser output protection from environmental effects and are ideal for beam sampling applications.
