The spectrograph employs the principle of single crystal Bragg X-Ray Diffraction to measure wavelengths by interpolation from accepted standard lines. It is suitable for the identification and determination of the charateristic emissions of elements and thus for X-Ray spectrum analysis. The instrument was manufactured by ADAM HILGER Ltd. to the design of Professor Laby and is the best preserved instrument surviving from his research activity. A full description is given in the Hilger Pamphlet with the instrument; alternatively see duplicate in Appendix A5,A6 in Vol 2 of Laby ‘s COLLECTED PAPERS.
