1. Lenses are made from transparent materials such as glass, polymers etc which are ground and polished to a desired shape.
2. A Lens is a Transmissive Optical Device that affects the focus of a light beam through refraction.
3. A simple Lens consists of a single piece of material, while a compound Lens consists of several simple lenses (elements), usually along a common axis.
4. Optics allow you to control your illumination pattern, either diffusing it or focusing it as your application requires. Secondary LED Optics provide a standard LED with collimation for spot, medium, wide and elliptical illumination patterns.
5. This allows a lot more control as they are illuminating and controlling literally straight from the light source.
6. 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 loss during the collimation process.
