Asphere Writer Available on the Customer Portal

When vendors receive an aspheric design for fabrication, they must convert the aspheric prescription to a format that can be read by the machines used for fabrication. This intermediate conversion step increases the possibility for transcription errors, which can lead to both time delays and increased costs. The CODE V Asphere Writer creates the files required for specific fabrication and testing equipment directly from the CODE V lens file, thereby avoiding this potential source of error.

Asphere Writer is a COM-based utility for exporting lens data either in QED Optical Data Interchange Format (QODIF), used by QED’s optical grinding/polishing equipment, or in the ASJ format required by ZYGO’s fabrication equipment and VeriFire™ Asphere interferometer metrology system. QODIF files are written using the extensible markup language (XML).

Asphere Writer also provides diagnostic plots for the beam footprint and surface departure for a selected surface. Viewing the surface departure from a base sphere or conic can be useful in verifying how easily an asphere may be tested and/or manufactured.

See the Latest CODE V Enhancements at Photonics West 2012, Booth #700

Visit us at SPIE Photonics West (January 24-26, 2012), booth #700, to get a demo of the latest CODE V enhancements. Our engineers will be showcasing features from version 10.4, just released in September 2011, including:

• Beam Synthesis Propagation (BSP) general complex field input, which gives users flexibility to customize the input beam description by importing the beam’s intensity and phase.

• BSP birefringent crystal modeling, which enhances BSP’s ability to accurately model beam propagation through devices that manipulate the polarization of light.

• BSP Pre-Analysis enhancements that make this feature more robust when used with systems with a Gaussian input field followed by small collimation elements.

• Glass Expert tool, now fully integrated into CODE V, which uses a unique algorithm to find the best set of real glasses for a user’s lens design that provides superior color correction (including the generation of apochromatic systems) while considering factors such as glass transmission, cost, weight and other criteria. The result is a practical final set of glasses that eliminates the need for time-intensive glass selection.
