High-Precision Optical Housing (Lens Barrel Holder)

About This Part

1. Key Features & Optical Functionality Stray Light Elimination: Features custom internal triangular thread profiles designed specifically for light trapping (anti-reflective shading) to eliminate internal reflections. Complex Multi-Axis Geometry: Integrates high-precision cross-bores, deep internal cavities, stepped diameters, and locating flats with tight concentricity. Strict Thread Process Sequencing: Manages multi-size micro-threads (including M1.6 and M2) with strict post-anodizing tapping to guarantee perfect thread fitment and zero binding. 2. Manufacturing & Process Advantages Precision Threading After Surface Treatment: To prevent anodizing buildup from compromising micro-threads, all M1.6 and M2 threads are precisely tapped after the chemical oxidation process, ensuring go/no-go gauge compliance. Controlled Sandblasting & Matte Black Anodizing: Parts undergo controlled sandblasting (60# mesh) followed by non-reflective matte black anodizing to achieve the ultimate light-absorbing, low-glare finish required for optical paths. Sub-Micron Critical Dimension Control: Key positioning diameters, concentricity, and axial runouts are held to within micron levels, strictly complying with ISO 2768-f (Precision Grade) standards. Micro-De-burring Under Microscopy: 100% manual and ultrasonic deburring focused on the roots of internal grooves and micro-threads to ensure zero par
