Light Collecting & Fiber Coupling Systems

Wide-Range Achromatic Condenser PS-2

Designed for collecting light from a sample within a wide spectral range and its effective transmission into an optical fiber or onto an entrance slit of a spectral device.

Consists of two achromatic UV-transparent objectives.

  • Spectral range: 200nm-2000nm
  • Light collection angle: 22
  • Front/back flange focal distance: 38.5mm
  • Entrance/exit aperture ratio F#: 1:3

Wide-Aperture Achromatic Condenser PS-3

Designed for collecting light from a sample within a wide aperture angle and its further transmission into an optical fiber or onto an entrance slit of a spectral device.

Consists of a meniscus and two achromatic objectives.

  • Spectral range:
    • preferable 400nm-1000nm
    • acceptable 400nm-1700nm
  • Light collection angle: 37
  • Front focal length: 29.5mm
  • Entrance aperture ratio F#: 1.5
  • Back focal length: 100mm
  • Exit aperture ratio F#: 3.3

PS-3 allows placing an Edge-filter in 25mm x 3mm holder in the parallel beam between two objectives.
