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
