• material：CaF (calcium fluoride)
• Design wavelength：587.6nm
• Effective aperture：80%

       Calcium fluoride crystals feature high hardness, and excellent resistance to mechanical shock and thermal shock. Featuring good transmittance in ultraviolet, visible, and infrared bands, this product series has been widely applied in scientific and technological fields such as lasers, infrared optics, ultraviolet optics, and high-energy detectors, especially with excellent optical performance in the ultraviolet band. Its high transmittance and small fluorescent radiation make it an ideal material for ultraviolet photodetectors, ultraviolet lasers, and ultraviolet optical systems.

       Lenses usually refer to the optical elements that diverge or converge the beam of light. Lenses can be widely used in security systems, vehicle-mounted systems, digital cameras, lasers, and optical instruments, while playing a significant role in astronomy, military, transportation, medicine, and other fields. OMTOOLS provides or customizes positive and negative lenses (including plano-convex, biconvex, meniscus, plano-concave, and biconcave) for different bands, with different focal lengths and apertures made of K9, fused silica, and other materials to meet diversified commercial and scientific uses.
