    Power Dynamic When this function’s Dynamic box is checked, you can simulate the fluorescence emission for various CHROMATUNE emission settings. The function works by dynamically modifying the fluorophore emission plots for the set wavelength, bandwidth and power as they are changed.

    Script Sequence tab Instead of writing scripts, the Sequence tab simplifies the method of creating an automated sequence of illuminations through its user-friendly interface. Within the tab, a series of visual steps are added, and each step contains illumination characteristics. Add steps containing the illuminations needed and when ready click the Run sequence button and the laser enables emission with the configuration of each step in a sequence.

    Script Sequence controls The sequence controls allow you to manage the steps in the sequence so that you can add steps, run the sequence and other functions as described in the following sections. Figure 76 Sequence controls Move step Click on a step in the sequence to highlight it, and then click either the up or down arrow to move the step’s position in the sequence order.

    Script Sequence steps Each step allows you to enter illumination characteristics in its attribute fields and menus for one of up to 16 steps in the sequence. In this way, you can order and sequence a series of 16 different illuminations. The step attributes are configured manually and described in the following sections.
