Tip: Reviewing glass data in CODE V
CODE V features an extensive catalog of glasses from numerous vendors, including Schott, Ohara, and even a special catalog containing numerous IR and UV materials. As we learn of updates to vendor catalogs, the catalogs supplied by CODE V are updated soon after and either included in a subsequent version of CODE V, or as a separate download from our website (see instructions to download glass database updates later in this Enews). View a log of glass database updates.
There are a few supplied tools to help you select appropriate glasses for your design. When you have a rough idea of the index vs. dispersion behavior or partial dispersion behavior that your application requires, there is a supplied macro called VP_PLOT.seq that will generate plots to compare these attributes for many glasses:
- Refractive Index vs. Abbe Value
- Partial dispersion vs. Abbe Value
- Refractive Index vs. Dispersion
To access the VP_PLOT.seq macro in CODE V, go to the Tools > Macro Manager menu and expand Sample Macros > Materials Information.
For engineers requiring special materials in a design, there is a similar macro available called SPECMAT.seq that will plot the Refractive Index and Partial Dispersion vs. Abbe Value as well. Enter three wavelengths that define your spectral band, and SPECMAT.seq not only lists and plots index, Abbe number, and partial dispersion, but it also tells you which of the special materials transmit in your wavelength band.
Once you have narrowed in on a few glasses, accessing details about each glass supplied by CODE V is easy using the Glass Catalogs option. To access the glass catalogs, go to Tools > Glass Catalogs...
Using this tool, you can get a detailed glass listing, which includes a listing of indices of refraction vs. wavelength, partial dispersion, transmittance, dn/dt, and more:
There are also summary listings to quickly compare characteristics like glass indices and transmission for glasses in an entire catalog:
For engineers using plastics and crystals, the PLASTICPRV.seq and OSACRYSTALPRV.seq macros are available in the Macro Manager > Sample Macros > Materials Information to define several plastics and crystals from the OSA Handbook of Optics. The macro manager also runs macros to load private catalog entries for Archer molded glasses (ARCHERPRV.seq), Rochester Precision Optics glasses (RPOPRV.seq), and Umicore IR glasses (UNICOREPRV.seq).
Choosing the right glasses for your design depends on many material properties, both performance based (index, dispersion, etc.) as well as non-performance based (price). You can use these tools in CODE V to learn more about the glasses you have at your disposal and how they fit within the constraint of your design and budget. To help you balance these properties, don’t forget that the Glass Expert is available to help guide you to complete glass selection quickly and efficiently.
CODE V Glass Catalog Updates Available for Download
Updates to the CODE V glass catalog, including the CDGM, Hikari, and Sumita manufacturers' catalogs, are now available for download from www.opticalres.com. In addition to download links, we have included more details about the glasses affected by this update and installation instructions.
CODE V User Group Meetings: Limited Space Still Available
There's still time to register for the annual CODE V User Group meetings! These free, one-day meetings will be held in Pasadena, CA (June 12), Mountain View, CA (June 14), and Rochester, NY (June 19). Join us for lectures, discussions, and presentations developed by OSG’s technical support and engineering staff. View the schedule and agenda.
To confirm your attendance, register online, send an email to ora_support@synopsys.com, or call 626-795-9101.
