miniRaman MRs accessories:

  • long working distance probe, f=30 mm (NA=0.05, laser spot size 50 µm)
  • middle working distance probe, f=15 mm (NA=0.1, laser spot size 15 um)
  • short working distance probe, f=6.25 mm (NA=0.34, laser spot size 3 µm)
  • immersion probe; ideal for in-vivo skin measurements, direct contact measurements of powders and liquids (f=6.21 mm, NA=0.38, spot size 2.5 µm)
  • sample holders
  • axial focusing accessories
  • light protection sample cover
  • objective covers
  • adapters for standard microscopy objectives (RMS, M25/0.75, M27/1)

If necessary, miniRaman MRs can be attached to the vertical positioning system for precise focusing on the sample surface and long term measurements
