The Xum Lens 7″ is a High-Transmittance Aspheric Fresnel lens.
Like a high-speed lens for a camera. It is nearly 20% more efficient than glass, and produces an ideal Fresnel light field; even and smooth, yet highly controllable.
The 7-inch lens is optimized for maximum efficiency, getting more light on target than any comparable system.
- High quality light.
- Wide zoom range.
- Very controllable.
- At full-spot the even light field is very usable.
- Very decisive cut with barn-doors.
- Beautiful shadow quality.
The lens is also a tilt/shift lens. You can tilt the lens at an angle to the illuminator within, to cast more light on one side of the beam. This allows you to light a green-screen from one side, and get uniform illumination, countering the normal falloff. You can also light a group of people from the side, and have them all be the same brightness from near to far. And you can light for movement, so as someone walks closer tot he light, they do not get brighter. Typically much larger lights would be used for these purposes, to get a big light far back so the light falloff evens out with more distance.
Any Lux Illuminator inserts into this lens and can be zoomed from a 12 degree spot to a 70 degree flood.
Accepts standard 7 3/4 Barn Doors, Gel frames, and the Xoft soft box directly, instantly.
