4X Beam Expander
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.
4X reimaging beam expanderSPZ17022
Screw optical assembly that images the plane 8 mm in front of the expander onto the CCD while enlarging it 4X. Fits 4.5mm recess and CS mount cameras.Request a Quote
UV converter assembly for 4X beam expanderSPZ17019
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 objectivesSPZ08261
Spacer assembly for above. One only needed for all expanders above
Beam splitter for expanders aboveSPZ17027
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 aboveSPZ17026
Additional beam splitter to mount to 1st beam splitter.
