*) IMPORTANT NOTICE:
REAL SPOT
lens is a highly efficient pure collimator lens, which optically functions in an
excellent way, giving a high intensity. REAL SPOT lens also reveals the chip level optical
structure of the LED. We recommend REAL SPOT lens for applications, where light
intensity is of highest priority, while we do not recommend it for white light applications,
where color uniformity is of high importance.
SMOOTH SPOT
lens is a pure collimator lens with light mixing properties. It smoothens
the beam pattern and makes a uniform color distribution over the whole beam angle. Light
intensity is lower than for the REAL SPOT lens. SMOOTH SPOT lens is recommended for
white light applications, where pleasant, high-quality illumination is wished.
