More information about dbOptic Optical Design Software for Windows
Users can step through the designs individually in the Rx Grid, with each Rx displayed in the Graphics Window and sort, filter or search for specific designs. For the current prescription, the Trace Menu allows display of spot diagrams and encircled energy plots and ray traces for the computation of aberrations. Aberrations considered include longitudinal and zonal spherical aberration, coma and OSC, chromatic aberration, secondary color, distortion, lateral color and field curvature. Printer output is available for most screens and views. The trace window for a Maksutov-Cassegrain telescope with field flattener lens is shown below. The oblique trace was performed for an object at infinity, 1.5 degrees off axis.
New prescriptions may be entered or existing ones edited using the convenient datasheet format shown below . . .
A fully-integrated glass catalog is included. . .

dbOptic is NOT an automatic lens design
program; however, it comes with a complement of tools which will assist in the
optimization of any design. The XY Plot Menu Command allows the plotting of aberration vs
surface design parameters, object distance and wavelength. From the plot
screen it is possible to reset a parameter for the purpose of reducing the magnitude of an
aberration. H'- L and H' - Tan U' plots are also available.
