Jumonji Optical Co., Ltd.

We manufacture and sell parallel plane glass plates for the optical and electronic industries.

We manufacture and sell mainly parallel plane optical glass plates for the optical and electronic industries. These plates are used for custom-made glass wafers, substrates, and so on. We offer a wide range of industrial parallel plane optical glass plates with an external diameter of 1–18” (we can wash the plates in-house up to 12”) and a plate thickness of 0.15–30 mm. We have established an in-house integrated production system including grinding processing, polishing processing, pure hot water washing, inspection, and shipment to respond to customers’ needs for extremely high surface accuracy, small volume to large-sized lot production, and short delivery time. We guarantee thickness irregularity and flatness within ±3 μm.

Other presentation

[Company strength]
Our main products are industrial parallel plane optical glass plates, and we offer a wide range, with an external diameter of 1–18” (we can wash the plates in-house up to 12”) and a plate thickness of 0.15–30 mm. In response to a growing number of requests for processing extremely small thickness and high surface accuracy, we have introduced 30 double-side lapping machines to our original specifications from 9B (small machine) to 24B (large machine). We have established an in-house integrated production system including processing, polishing processing, pure hot water washing, inspection, and shipment to respond to customers’ needs such as extremely high surface accuracy, small volume to large-sized lot production, and short delivery time. Another of our strengths is that we guarantee thickness irregularity and flatness within ±3 μm. We acquired ISO 14001 certification in 2002 for environment-friendly factory management, such as industrial wastewater control. 

[Business description]
Our company started out manufacturing optical filters under contract for HOYA Glass in 1977. We have since been manufacturing and selling parallel plane optical glass plates for the optical and electronic industries. These plates are used for custom-made glass wafers, substrates, and so on, and are our main products for meeting various customer needs. We are trying to expand sales channels and develop novel technologies through trial-order production, which has been increasing recently. 

[Industry]
Manufacturing of parallel plane glass plates for the optical and electronic industries

[Representative's message]
It is difficult for us to expand if we continue to manufacture and sell just parallel plane optical glass plates for measurement devices and electronic industries. We seek to develop our business into new areas and industries by utilizing our special glass processing technology. We will use J-GoodTech to find new business opportunities, obtain various information and contact overseas companies.



[Company structure for market development/overseas expansion]
We have a dedicated Sales Channel Development Team in the Administration Department to accurately collect a wide variety of needs from customers. We also have technical staff who answer customers’ technical inquiries by sharing information with the Sales Channel Development Team.
