Discover Orbiter's Projection Optics. The new Orbiter Projection Optics 25° and 35° provide unparalleled precision in every detail allowing for crisp projection of a light spot, as well as immaculate gobo projection and precise shutter cuts. The field of light is entirely even and without color aberration. The projection has no visible hot spot or drop to the edge and the depth of field is outstanding. The Orbiter Projection Optics are a great addition to the already existing Orbiter Fresnel Lens 15-65°.
