Distance Size

Var­i­ous lenses are avail­able, depend­ing on the dis­tance from the lumi­naire to the pro­jec­tion sur­face and the size of pro­jec­tion required.

Stan­dard (85mm focal lens)
A medium focal lenght is suit­able for most sit­u­a­tions. The stan­dard lens gen­er­ates a pro­jec­tion witch a diam­e­ter of approx. 4.5 m from a dis­tance of 10 m.

Tele­foto (150mm focal lens)
A tele­photo lens with a large focal length enables a smaller pro­jec­tion with more inten­sive light. Tele­photo lenses enable bright pro­jec­tions across large dis­tances. From a dis­tance of 10 m it pro­duces a pro­jec­tion of approx. 2.5 m diam­e­ter.

Wide angle (63mm focal lens)
A wide-angle lens increases the sub­ject. The light quan­tity is dis­trib­uted over a larger area and the pro­jec­tion appears darker. From a dis­tance of 10 m it pro­duces a pro­jec­tion of about 6.5 m diam­e­ter.

Extra wide (45mm focal lens)
Such an object per­mits an extra-large focal length for par­tic­u­larly small dis­tances from the pro­jec­tion sur­face. It pro­duces a pro­jec­tion of approx­i­mately 8.75 m diam­e­ter from a dis­tance of 10 m.
