The Martin Professional ELP Static Lens Tube, with a 26-degree beam angle, is a specialized optical accessory designed for use with specific high-output LED moving head spot and profile fixtures. It is engineered to transform the fixture's native zoom range into a fixed, narrow beam of light, ideal for applications requiring sharp, defined aerial effects, intense beam looks, or long-throw projection in theatrical, concert touring, and permanent installation environments. Constructed from high-grade optical glass with anti-reflective coatings, the lens tube minimizes light loss and internal scattering, ensuring maximum intensity and clarity are maintained from the light source. The precisely calculated 26-degree field angle provides a concentrated output that enhances the fixture's throw distance and visual impact, making it particularly effective for creating powerful beam shafts through atmospheric haze or for tightly framing architectural elements.

Installation of the lens tube is a straightforward process, typically involving secure mounting onto the fixture's existing lens carriage or front assembly via a dedicated locking mechanism. This conversion effectively overrides the fixture's motorized zoom functionality, locking the optical path into a single, performance-optimized configuration. The tube is designed to maintain the fixture's overall color rendering, gobo projection sharpness, and prism effects without introducing chromatic aberration or significant distortion. Its robust construction ensures it can withstand the mechanical vibrations and thermal changes associated with live event use, providing a reliable and consistent optical modification. For lighting designers, this accessory offers a tool to standardize the beam characteristics across multiple fixtures in a rig, ensuring uniform beam width and intensity for cohesive visual compositions.

The practical use of this fixed lens tube expands the creative and technical possibilities of compatible fixtures. In beam-heavy show segments, it allows fixtures to perform more like dedicated beam lights, with a tighter, more laser-like quality. For profile applications, it ensures a consistently narrow field for sharp gobo projections across long distances. The 26-degree angle represents a calculated balance, offering a significant narrowing from typical wide zoom positions while retaining enough spread for functional wash effects when combined with frost filters. By offering this fixed optical path, Martin provides a solution for professionals who require predictable, high-intensity output from their fixtures, enabling precise planning for throw distances and beam visibility in large-scale productions where optical consistency is paramount.
