• To provide even more flexibility to target specifications a new option Target Interpolator has been implemented. It can be invoked through the [#] button next to the "Number of spectral points" and [?] entry fields in the Target editor window.. Using this option you can modify (increase or decrease) numbers of spectral points in a selected range using piecewise-linear interpolation or spline interpolation of targets in this range. This option is also convenient for fast specification of targets with piecewise spectral dependencies.

Example 2. Dense wavelength grid in target: the number of wavelength points is increased using the new option. No undesirable transmittance peaks appear in the course of the design process (put the mouse button on the right picture)

• The concept of User Defined Targets (UDT) has gained further development. It is now possible to include/exclude Light Source and Detector characteristics in calculating UDT. This can be done through the Configuration -> Settings dialog using the respective check-box at the Source/Detector/Cone/Integral tab of the General Configuration window.
