  • Zoom: x1 to x6.3
  • Eyepieces: x10
  • Beam splitter with C-mount camera adapter
  • Coaxial episcopic illuminator
  • Maximum sample height: 300mm
  • Maximum sample depth: 300mm
Volpi Intralux 5000-1 Cold Light Source
  • Light source: halogen reflector
  • Constant colour temperature
  • Ring illuminator
  • Filters: red, green, blue, yellow, daylight
