Optical efficiency is determined by measuring the ratio of light collected after the optic and dividing by the total amount of light without an optic directly at the LED source.

The simple answer is yes. Carclo optics uses a technology called total internal reflection (TIR), so there is light lose during the collimation process.

In general when talking about lens optics the larger the optic the easier it is to collimate light into a tighter pattern. Another consideration when trying to achieve a tight spot is the size of the LED die. The smaller the size of the die the tighter the spot.
