Ball Lens Cap consists of a high-precision Micro Ball sealed in a can cap made of sealing alloy with our original glass frit. The standard types, such as TO-56 and TO-46, are available upon request. <MK-CAP> MK-CAP has high productivity and competitiveness by using our original glass manufactured consistently from glass melting and is suitable for FTTH application. Besides, super high refractive index lens RH-21 can achieve the extremely high coupling efficiency and contributes to miniaturization of module.
