二光ライト Company Profile

Since 1953, we have been manufacturing optical and industrial precision plastics in Nerima (Narimasu), Tokyo. We have particularly supplied precision parts made of optical and industrial plastics. From molds to precision molded parts, and from prototypes to mass-produced items, we prioritize flexibility in supplying our components.

We handle everything from molding (including prototype production) to post-processing (painting, printing, and simple assembly), and we also arrange for handmade prototypes and cast prototypes. Our in-house products include glass retaining rings for photographic filters used in cameras and camcorders. Photographic filters have methods such as riveting, springs, and screws to secure the filter glass within the frame. The rings we offer are plastic rings with an outer diameter screw cut of approximately 1.5 mm that screws into the inner diameter thread of the filter frame (special rings sized 37 to 77 mm), which may be necessary for those in need. We also have various caps in different sizes (polyethylene and ABS).
