| Refractometer: Abbe for Multi-Wavelength have the ability to measure Refractive index or Abbe number of liquids or solids at different wavelengths ranging from 450 to 1,100nm using interchangeable filters. For measurement at wavelengths ranging from 681 to 1.100nm, the optional Near Infrared Ray Viewer (RE-9119) is required. Measurements are displayed digitally for easy reading. Measurement can be achieved by matching the boundary line with the intersection point of the cross hairs. Optional DP-21 printer available. |
