CODE V 9.82 Service Release Available for Download
We are pleased to announce the availability of the latest CODE V Service Release, CODE V 9.82 SR1 (click here to download). This bug fix patch can be applied to CODE V 9.82 and includes the following enhancements and bug fixes:
- The computation of the overlaid Airy disk size in the Analysis > Geometrical > Spot Diagram (SPO) was incorrect for systems with dimensions of inches or centimeters (it was correct for millimeter dimensions). This has been fixed.
- Information for two Hoya glasses has been updated. Of particular significance is that Hoya has changed the dispersion equation coefficients for EFL6 glass without changing the glass designation. Please review any designs that may be using EFL6 glass with the obsolete dispersion coefficients. In addition, the transmission data for Hoya TAF3 glass has been updated.
- The computation of MTF using the MTF error function via Optimization > Automatic Design > MTF (AUT), was incorrect if there was significant variation in transmission as a function of wavelength. This situation is not typical, but would impact diffractive optical systems with non-ideal blaze types (BLT command). It may have also impacted systems when polarization ray tracing was enabled and there was significant variation in wavelength transmission due to coatings. This has been fixed.
- When using private catalog materials (PRV) with the glass manufacturer's Laurent's dispersion equation, Lens > Add Private Catalog Glass > Dispersion formula (Glass Manufacturer's Laurent, GML keyword), the computation of indices was incorrect if the final term in the series was the A3, A4, or A5 term. The computation was correct for A0, A1, and A2, and when all A0-A6 terms were used. Since the GML form was added specifically to model Hikari materials with non-zero values of A0-A6 defined, user would not generally encounter this. This problem has been fixed. Note that this problem only impact the GML dispersion equation form, the standard Laurent dispersion equation form (LAU keyword) computed indices correctly.
We strongly encourage all CODE V 9.82 users to download and install this update.
Quick Tips From CODE V Tech Support
Several new tips from ORA's CODE V Technical Support team are featured in the 2008 CODE V User Group presentation "CODE V Tips and Tricks", available for download from the ORA Customer Service web site, www.oraservice.com.
This presentation includes the following tips:
- How to import your CODE V environment (e.g., GUI customization) when upgrading to a new version of CODE V
- Using barrel tilt tolerances to rotate lens elements automatically
- Generating tabbed output windows with a multi-line command
- Modifying your lens prescription to include surface error effects
- Using PSPad for enhanced macro writing
These and other presentations from the 2008 CODE V User Group Meetings can be found on www.oraservice.com under the CODE V User Group Presentations link.
