Varilux S processing adds some additional complexity to the digital interface. Additional steps in the blocking and verification process require the files received back from Essilor to be saved somewhat differently.
On the Digital Type screen, for Essilor only, is a box titled "Extended Paths". When clicked, a new box is presenting that allows paths to be specified for the files that will be created for different devices, based on the information returned from Essilor:
Within the LMS file sent back by Essilor are sections identified by LDCRYPT=DEO:CLBS, LDCRYPT=DEO:CTA, etc. Following the LDCRYPT label, data is encapsulated by _ZZENCRYPT and _/ZZENCRYPT - this data will be extracted into files and saved in the folders indicated by the entries above, and using the file naming convention identified above. If the "Base Name" above is "O", the order number will be used as the base name for the file created; if the "Base Name" entry is "T", then the tray number will be used.
Most designs use the "Path" column; if the lens design is set up with the option "Use Alt DEO paths", then the file(s) will be created in the paths indicated in the "Alt Path" column. If the "Alt Path" entry is blank, then the entry in "Path" will be used.
For example, for an LMS file containing several blocks of data, using the above naming conventions and paths:
