In stage performance art, light is not only a lighting tool, but also the key to emotional expression and atmosphere creation. As the core component of stage lighting equipment, optical aperture carries multiple tasks of adjusting light, shaping visual focus and enhancing artistic effects.
This article will take you into the world behind optical aperture, from design to assembly, to explore how countless fine mechanical iris devices are transformed into charming light and shadow on the stage through precision processing.
The role and core composition of mechanical iris
The mechanical iris plays a role in controlling the amount of light, affecting the depth of field and creating artistic effects in stage lighting. Its aperture ring and aperture blades are the core components for adjusting the amount of light entering, and the size of the aperture is controlled by rotation, movement, extension and contraction to change the stage lighting effect. The complex geometric shapes and precise size requirements of the aperture equipment make CNC the most ideal processing choice.
CNC machining: the best choice for precision manufacturing
1. Complex geometric shapes and high consistency realization: CNC machine tools can provide extremely high processing accuracy, which can reach micrometer or even nanometer levels. It is of great significance for mechanical irises that require extremely high-precision aperture blades to achieve light control.
2. Flexible material processing capabilities: Since the mechanical iris can reach a high temperature of 900°C under long-term working conditions, factors such as durability, strength, and thermal stability need to be considered when selecting materials. CNC machine tools have this strength. From metals, plastics to special composite materials, CNC machine tools provide flexible and diverse material processing capabilities.
Crystallization of intelligent manufacturing technology: self-developed fixtures unlock new realms of special processes
In Harman’s iris aperture equipment project, Airy combined its own years of precision manufacturing wisdom and the unremitting efforts of the technical team to finally provide Harman with a complete set of solutions, which not only realized the special processing operations of mechanical iris equipment in etching patterns, PVD coating to enhance wear resistance and optical properties, PTFE spraying, etc., but also used special dedicated iris assembly jigs to complete the rapid and accurate assembly of parts, effectively solving the complex problems in the precision manufacturing process and vigorously promoting the development of precision manufacturing technology.
