Condensers for apertures matching

Close Menu
 


Condensers serve for working apertures matching at an image formation. Our condensers, being used with optical waveguide, change the entrance aperture of the beam which exits the optical waveguide and match this aperture with the entrance aperture of the spectral device.

Application of F-matcher allows:

  • Matching optical waveguide apertures with spectral devices apertures
  • Providing high quality of the image over the slit height of our spectral devices
  • Reduction of the stray light
  • F-matcher can be mounted on the exit slit of the device for collection of radiation to the waveguide  

More precise information on the apertures matching principle you can find here.

F-matcher 1xVIS

 

  • Magnification – 1 fold
  • Front and back operating parts – 21 mm
  • Spectral range – 400…..2500 nm

Constructively simple and easy in operation this condenser collects radiation from the object (maximal angle of coverage is 28.8 degrees) or optical waveguide (maximal aperture Na=0.15) and transfers it to the entrance slit of the spectral device without losses and stray light. Two achromatic in a wide spectral range objectives allow obtaining a high-quality image of the waveguide end in the plane of knife blades of the entrance slit of the spectral device. Replaceable diaphragm prevents propagation of the stray light. The peculiarity of this condenser is its operating entrance aperture Na=0.15, allowing operation with the waveguides having small aperture (Na=0.12). It is constructively possible to mount a filter wheel with light filters.
