The relative size of the aperture expressed as a percent of maximum area. Optical Bench Detector Beamsplitter Source Accessories Comments Filename The type of detector used. The type of beamsplitter used. The type of source used. The accessories used to collect the spectrum. Any comments about the spectrum that you have recorded in the Collection And Processing Information window. The filename of the spectrum. 100 Thermo Nicolet
See “Spectral View” for a description of the Sampling Information option. Specifying X-axis display limits for new spectral windows You can specify the X-axis limits for displaying spectra in new spectral windows by typing the desired values in the Start and End text boxes in the X-Axis Limits box. The most commonly used starting and ending limits for wavenumbers are 4000 and 400, respectively. See “Specifying an X-axis format” for information on selecting an X-axis format. Security options If you have the DS option, the Security options are available in the Options dialog box (unless the Show Security Options In This Configuration option, listed below, has been turned off). The table below shows what you can specify with each option. To do this... Prevent existing files from being overwritten when you save files. Save the original data, such as background and sample interferograms, with collected spectra. Require users to provide a digital signature when they perform certain operations. Display the Security tab in the Options dialog box when the current configuration is used. Specify the directory location of the configuration files you will assign to users as their default configurations. Use this feature...
