WebHemispherical lenses are made by cutting a spherical (ball) lens in half, facilitating easier mounting compared to spherical (ball) lenses. These lenses are available with Fused Silica, Silicon, Calcium Fluoride, or Zinc Selenide substrates to provide coverage for applications from the ultraviolet to the long-wave infrared. Hemispherical emissivity of a surface, denoted ε, is defined as where • Me is the radiant exitance of that surface; • Me° is the radiant exitance of a black body at the same temperature as that surface.
