Control the spot size of your LED light

A tunable condenser lens is the ideal choice for illumination systems based on LEDs. In combination with secondary optics (TIR lens or reflector), large illumination angle variations can be achieved while maintaining an excellent spot quality and a very high optical efficiency. The low-dispersion lens material prevents color errors from spoiling the spot quality.

There is not a more elegant way to flexibly adapt the lighting angle of your illumination system than with a tunable condenser lens. Traditionally, lighting angles are adjusted by axially shifting a fixed lens. Yet, axial shifting of fixed focus lenses produces spherical aberrations that manifest themselves in undesired intensity rings and bad illumination spots. Furthermore the optical efficiency significantly drops when the fixed lens is moved away from the light source. These disadvantages can be overcome by using a tunable condenser lens.
