Obtain 3D specification files
To examine all 3D specifications, save the files to your local drive and open them with your 3D application.
Lens colors in 3D files are solely for visual representation; consult the Datasheet for accurate lens type and color information.
In the event of a mismatch, the dimensions in the datasheet take precedence over the 3D specifications.
