The basic equipment Abbe B, is also deliverable with measuring prisms for higher or lower nD-range instead of standard prism. (Price on request.)

When dark samples are measured, or the dispersion of a substance is high, we recommend the use of our universal spectral lamp unit with sodium spectral lamp. Furthermore, the lamp unit makes it easier to adjust the measuring prism.
