Order Sorting Filters

These filters are used for order sorting. Choose a filter that starts transmitting just below the wavelength range of interest. Remember that it will transmit any second order above this cut-on wavelength. As an example, if you want to scan from 450 to 900 nm, choose a 51272 Filter, which transmits from 415 nm. This will eliminate second order problems to ~780 nm. To measure longer wavelengths, stop the scan at 700 nm and insert a second filter, model 51330, for second order blocking to ~1300 nm.

If you are scanning over a very wide band, as with our Cornerstone^TM, multiple grating instruments, you should consider using a filter wheel so you can easily switch filters during a scan. The filter wheel can be placed under CornerstoneTM control, and programmed for the "switch over" wavelength(s).
