Optical Design Software:
Optical Design for Personal Computers
"If other optical design software you have tried leaves you with the impression that a graduate engineering degree is a prerequisite, you will appreciate the power and simplicity of dbOptic."
dbOptic is a comprehensive optical design software program utilizing Microsoft Jet (Access®) Database technology to store, edit, sort, filter and update optical designs and glass catalog data. It can accommodate up to 99 surfaces per design (Rx) and a variety of surface types including spherical, flat ,elliptical, parabolic, hyperbolic, stops (called "Iris" surface type) and surfaces defined by an eighth degree polynomial (Ax2 + Bx4 + Cx6 + Dx8).
New prescriptions are entered surface-by-surface using a convenient datasheet format with each new surface displayed in the Graphics Window in real time. A fully featured optical design editing capability is included that enables editing individual surfaces, moving and "flipping" surfaces or elements and inserting new surfaces or complete designs from the database. New designs and lens libraries may also be imported into the database. The user may set defaults for new designs which include selection of English (in) or Metric (mm) units, object space medium and object distance and design wavelength in nanometers.
"dbOptic Optical Design Software can provide a quick solution to your immediate optical design and imaging problem."
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.
The current version of dbOptic offers polychromatic spot diagrams, imaging of extended objects and support for higher monitor screen resolution settings. Spot diagram for a double gauss photographic lens is shown below.
New prescriptions may be entered or existing ones edited using the convenient datasheet format shown below . . .
A fully-integrated glass catalog is included in the dbOptic optical design software package. . .
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.
dbOptic, the Optical Design Database Program, contains many more features than can be covered here. For more information . . .
