4X Beam Expander

4X Reimaging Beam Expander For Very Small Beams
Description: 

Beam expanders are designed to work with C-mount threaded cameras that have 4.5mm imager back focal spacing or with CS (12.5mm) back focal spacing. The 4X beam expander is an expanding telescope that images the beam as it looks at 8mm from the end of the expander onto the CCD while enlarging the image 4X.

Accessories

Customers that purchase the above items also consider the following items:
  • UV converter assembly for 4X beam expander

    SPZ17019

    Screw on assembly which has UV plate that converts 193 - 360nm radiation to visible. This plate is at the object plane of the 4X expander so it produces a 4X enlarged image on the CCD

  • Spacer assembly for objectives

    SPZ08261

    Spacer assembly for above. One only needed for all expanders above

  • Beam splitter for expanders above

    SPZ17027

    45 degree angle wedge beam splitter which mounts onto beam expander. Reduces beam intensity by ~20 times. For spectral range 190 – 2500nm. Introduces 35mm extra beam path to object plane.

  • Additional beam splitter for above

    SPZ17026

    Additional beam splitter to mount to 1st beam splitter.
