The Descriptions for both (R) and (C) need to be Added

[edit]

I have attempted to edit the Summary section, to include the Descriptors for R and C, which appear to be missing. R represents Parabolic Refraction, where C represents Collimated Light.

In addition, there are several Grammatical inclusions which should be made. Since I am unable to Edit, please let me know if you need assistance with the Commas (,) which should be added, in order to make this Image Description Summary more grammatically correct.

Regards,
