Set scanning parameters | | | | | | | | | | Function 6 on the main menu allows four wavelength scans to be programmed, in much the same way as function 1 programs the wavelength positions. Scans are allowed to run in either direction, anywhere within the wavelength range 300-800nm. The scans occur as a series of discrete steps, with the wavelength incrementing through the range in intervals as low as 1nm. With the shortest intervals this approximates arbitrarily closely to a continuous scan, but if desired much broader wavelength intervals can also be selected, as can a much narrower scan range. An individual scan may thus contain anywhere between a few and several hundred individual measurements. The scan adjustment menus allow refining of the way the scans are performed. Information on these functions can be found in the technical manual. | | | | | | | | | | 7. Run scanning program This menu option has exactly the same functionality as the "run wavelength program" function, but there are some differences. For example, there is no facility to change the program number while a scan program is running, since that is unlikely to be of so much practical use. This is because different scan programs are likely to be used in conjunction with, say, different microscope objectives, which are only going to be changed between, rather than during data acquisition periods. However, the control of scanning programs by an external trigger pulse is exactly the same as for the wavelength programs. | | | | | | | | | | __Page 16 | | | | | | | | | | | | | | | | | |
