Chauvet Professional Ovation Ellipsoidal HD Lens Tube - 36 Degree

This lens tube brings high-definition optics to any ERS-style ellipsoidal fixture, Chauvet Professional's own Ovation ellipsoidals included. Two aspheric lenses work together inside a rugged housing to hold focus and deliver a crisp, well-defined gobo edge rather than the soft-edged projection a lower-grade lens tube produces, and an integrated gel frame holder with a standard gel frame ships in the box.

It is sold as one of six fixed focal lengths (5, 10, 14, 19, 26, 36, and 50 degrees), so the beam angle is set by which tube is ordered rather than a zoom mechanism - this listing is the 36 degree version.
