From the Zeiss catalog:

Spectroscopic Eye-piece (Micro-spectroscope) after ABBE. Achromatic upper lens adjustable to focus on the slit as above. Mechanism between the lenses for contracting and expanding the slit by symmetrical movement of the laminae (after Merz) by means of the screw F; these may be sufficiently widely separated so as to open the whole visual field. The screw H serves to reduce the length of the slit to such an extent, that, the comparison prism being inserted, the image of the object under investigation completely fills the slit. Comparison prism with lateral frame and clips to hold the object and the mirror. All these parts in a drum combined with the eye-piece.

Above the eye-piece, an Amici prism of great dispersive which may be turned aside about the pivot (K) to allow of the adjustment of the object being controlled, the prism being retained in its axial position by the spring catch L. A scale is project on the spectrum by means of a scale-tube and mirror attached to the mount of the prism; the divisions of the scale indicate decimals of a micron. the wavelengths of the section of the spectrum superposed by them. The screw P is for adjusting the scale relative to the spectrum.

The apparatus is inserted into the tube in place of the ordinary eyepieces and is clamped to the former by means screw M in such a position that the mirrors A and O serving to illuminate the comparison prisms and the scale ot wave-lengths are simultaneously illuminated by sun-light. In case, including set of lithographed scales for recording observations.
