Spectrometer Accessory Selection Guide

For both monochromators and spectrographs, Oriel continues its modular approach to designing instruments and components. Like pieces of a puzzle, our components fit together; you can add and interchange accessories. Our universal flanging system allows this coupling. Most components and instruments have a male flange, a female flange, or both. In the case where you need to couple two accessories with like flanges together (i.e. two male flanged components), we offer coupling rings, to help make the transition. A wide range of sources, fibers, and optics are available to help you measure light.
