Innovative B+M Structure texturing of lenses

Lenses with structural surface remove the need for diffusing plates and prevent the related loss of light.  There are three versions of these structures: Smooth,  Medium, Rough

Beam Angles and Focusing (secondary optics)

These molded glass Aspherical are suitable for all LED types (e.g. High-Power-LEDs with large-scale dice or normal LEDs with only one dice).The typical beam angle of an LED of 120° can be reduced to below 8° with our optics without any difficulty (at the same maintaining high efficiency and homogeneous illumination). The angle may be modified individually by changing the distance between lens and LED, also called “zoom-able” effect.

RGB-LED light mixing

An excellent optics for all RGB-LEDs to achieve dynamic color appearances.  Standard 4-chip LEDs as well as large-sized RGB applications may be mixed in a homogeneous manner.
