Fixed Slit Holder, 77250 Monochromator and MS125 Spectrograph

The 77294 Fixed Slit Holder may be mounted to the input port of an Oriel Spectrograph, or at the input and output ports of many Oriel Monochromators. Using fixed slits is the most economical choice when a single, non-adjustable height and width are required. Fixed slits should also be considered when a few select sizes are required, as they provide excellent repeatability. A number of fixed slit models are available in various sizes (ordered separately). When ordering fixed slits, the input and output slits should be of the same size. Monochromators and Spectrographs require fixed slits to be installed into the 77294 prior to operation.

The MS260i Spectrographs and 77250 Manually Operated Monochromator require purchase of the 77294. It is automatically provided with preconfigured Cornerstone 130 and Cornerstone 260 monochromators, the Model 78877 Line spec System and MS125 Spectrograph.

Note: fixed slits are ordered separately. They should be the same size at the instrument's input and output ports.
