Silicon Aspheric Lenses are high performance, lightweight solutions for MWIR applications, and are ideal alternatives for costly ZnSe lenses and brittle Germanium lenses. Silicon Aspheric Lenses feature the mechanical and thermal properties required to withstand many of the effects of harsh environments including fluctuations in temperature and pressure. Because silicon is a low density material, these lenses are also ideal for weight-sensitive systems, such as those found in many defense applications.
