ND精工 Company Profile

Our general-purpose integrating sphere adopts a white reflective surface with uniform and high reflectivity. Additionally, even if the diffusing surface becomes contaminated or deteriorated, we can provide regeneration and maintenance services, ensuring stable performance over a long period. Furthermore, by replacing sockets and accessories, it can flexibly accommodate various light sources, and customization according to applications is also easy. We offer standard integrating spheres with specified sizes and port numbers, allowing for rapid implementation! Of course, we also accommodate custom orders and the production of large integrating spheres up to 2 meters, providing optimal products and services tailored to our customers' needs, from research and development to industrial applications.

Commonly used stones have several names, but fundamentally they are "granite." In the Asian market, Indian stones are widely used. Compared to metal materials, they possess many characteristics, such as superior precision and stability, and they do not rust or corrode. Although they are often perceived as expensive due to the difficulty of processing, there are actually many products available at prices comparable to metal products, as well as more affordable options. Since we own our own factory, we can customize products to meet customer needs beyond standard products. Our company produces and manufactures a range of items based on customer design drawings, from "measuring tools for general processing such as stone plates, square masters, and optical breadboards" to "large stone bases essential for the manufacturing of precision processing equipment like LCDs, semiconductors, and laser processing machines," as well as "large stone bases for precision measuring devices such as 3D measuring devices, CT inspection devices, and air bearing sliders." Furthermore, leveraging our experience in stone processing and CNC machine manufacturing know-how, we can also provide proposals related to design, production, and assembly.

Hello, this is ND Seiko. Suddenly, do you know why images appear inside crystals? Products like those you see in souvenir shops or as commemorative items, where "pictures are drawn inside the crystal." In fact, these are made using a special laser technology that carves only the interior without touching the surface at all. The 3D crystal and glass inner engraving machine (3D Green Laser) that we handle generates tiny fracture points (micro-cracks) inside the crystal. By creating tens of thousands to hundreds of thousands of these points, we can bring three-dimensional images or text to life. We also arrange for crystals for processing and LED bases, and we provide thorough after-sales support after installation.
