PARTICULAR ADVANTAGES OF OPTICON’S

OBJECTIVES

  1. Single material construction
    (uniform coefficient of expansion)
  2. Secondary mirror is integral
    (machined into) to “spider” assembly.
  3. Objectives are hand assembled
    in an interferometric setup, each pair of mirrors are optimized as a set for maximum
    resolution.
  4. Near “diffraction limited”
    performance.
  5. Optical surfaces can be “low
    scattered” for use with high power UV laser

ADVANTAGES
OF REFLECTIVE OBJECTIVES

  1. Achromatic in UV thru IR
  2. Long working distances
  3. High Numerical Aperture
