A small-diameter pin from Sanwa Creation that improves the light-gathering performance of optical devices.

In the optical equipment industry, precise control of light and efficient light gathering are crucial factors that influence product performance. In particular, high-precision pins are essential for the positioning of optical components such as lenses and mirrors, as even slight misalignments can affect light transmission and focal length, potentially degrading the performance of the final product. Sanwa Creation's small-diameter pins provide optimal solutions to these challenges with high precision and a variety of materials and shapes. 【Application Scenarios】 - Positioning of lenses and mirrors - Alignment of optical fibers - Assembly of optical sensors - Precision adjustment of laser equipment - Manufacturing of microscopes and telescopes 【Benefits of Implementation】 - Improved light gathering efficiency - Stabilization of optical performance - Enhanced product quality - Reduced assembly time - Improved yield
