Manually tunable condenser lens

ML-25-50 Lumilens
 

The shape of our manually tunable condenser lens can be adapted from flat to strongly convex by rotating an adjustment ring. A tunable condenser lens is the ideal choice for illumination systems based on LEDs. In combination with an LED lens (TIR lens) 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.
 

Advantages
-. One spot light suits various applications 
-. Excellent spot quality for all tuning states (no intensity rings as in fixed lens shifting).
-. No color errors due to low-dispersion lens material 
-. Highest optical efficiency (low light loss) 
-. Easy to motorize

A tunable condenser lens is the ideal choice for illumination systems based on LEDs. In combination with an LED lens (TIR lens) 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.

The ML-55-106 was specifically designed for larger illumination applications. With the presented designs, beam angle variation of 45° to 10° can be realized with combinations of LED and TIR Lens providing over 2000 lumen of lighting power. Further information about the implementation of the ML-55-106 can be found in the application note in the download section below.
