The Prism Convex provides a beam edge quality tighter than a Fresnel and close to a soft-focused profile. This unit can be provided with a rotatable barndoor.
Colour frame and integral wire guard are standard on all Cantata luminaires.
The PC basic design dates back to the first days of stage lighting, but the modern version has one important difference. This lantern uses a modified plano-convex lens with a pebbled effect on the plano (flat) side. The pebbled effect gives the beam its characteristic soft edge. The edge of the beam is slightly harder than a Fresnel, but is not hard edged. The pebble convex lens uses the efficiency of the plano convex lens and gives the light a softer edge. Like a Fresnel, there is one focussing knob to change the beam angle.
