1, 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.
2, The simple answer is yes. Carclo optics uses a technology called total internal reflection (TIR), so
there is light lose during the collimation process.
3, Lenses are made from transparent materials such as glass, polymers etc which are ground and polished to a desired shape. A Lens can focus light to form an image.
4, 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.

How do secondary lens optics work?
- LEDs generally emit light at a 120-degree viewing angle. LED applications that require more focused light often use a secondary optic that is placed over the LED, which internally reflects light into a spot, medium spot, wide spot or elliptical spot pattern.
- Most optics are cone shaped and need an optic holder to hold the lens in place over the LED.
- The lens itself clips securely into the holder, but the holder does need to be externally adhered. In the case of LED stars, optic holders have four legs that sit down into the grooves of the star board.
