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 (135mm 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.
