Antique Scientific Instrument Spectroscope / Spectrometer by Adam Hilger

Updated to include prism in the sale. While the prism is not exactly period correct it is not far off. It is a high quality flint glass prism, produced in England, c1950. A Massive & Spectacular Spectroscope By Adam Hilger, London. The spectroscope stands on a massive cast iron stand with a tall column supporting the main workings of the instrument.

At the top is the large circular stage finely engraved around the edge. The collimator tube is fixed at 0 with the telescope tube able to rotate freely around the stage. The telescope tube has a vernier scale and a friction clamp with fine adjustment. Above the vernier is a magnifying eyepiece on an arm. Above the main stage is the secondary prism stage that holds a prism in a clamp. This stage can also be freely rotated and a scale is engraved around the edge. The telescope has course focusing via the 2 large wheels at the top. This scientific instrument would have been used to study the spectrum of light in fields ranging from astronomy, physics, chemistry and biology. I have seen this spectroscope referred to as the No. 1 Spectroscope and The South Kensington Model and suggestions that is it is a very early Adam Hilger model from other sources. However, I only have access to the online catalogues from 1920 and 1928 (links below) and I have not been able to find this exact model there, so I cannot confirm this. Width: Depends on how you setup the arms of the devices. Realistically you would need a min. Of 50 cm width to display. Mechanical: No visible damage, everything seems to move as expected.

Optical: I have not tested the optics to create a spectrum, however a visual inspection of the lenses doesn't show up any issues. What it costs me, it will cost you and no more.
