To Deliver Our Quality Products to the World

light optical work Ltd's  products

We provide a full range of services encompassing development-design, trial production, manufacture, packaging and shipment (including export) of binoculars, Riflescopes, spotting scopes (field scopes) and other optical instruments according to the customer's desired specifications.

A customer contacts us saying, "I want to market a x8 binocular to the U.S." Our business process swings into action. We tell the customer about products that we've already developed. Or, if new development is judged necessary, we can offer a rough estimate from our experience to date. And the negotiations can be in English, not just Japanese.

It truly takes large amounts of effort, time and expense to develop a product into a marketable item that end users can actually put in their hands in a store or elsewhere in the field. That whole series of operations can be left to us. We will also provide after-service in the post-delivery period, responding to your needs in faithful accordance with the items determined in the consultation when you contact us.

We said above that a transaction starts from just a few words - "This is the kind of thing I want ..." - but in order to turn that into a product we will naturally have to hold detailed consultations with you. They may seem too detailed, and we may even reveal a stubborn side as regards specifications. Still, the deeper our involvement with the customer, the finer the outcome product will be. Which means we take another step in our growth. All in order to deliver top products to the world.
