IR Cut Filters & Dicing

Message from the President

At TAMA Electronics, we have continued to focus our business on contract machining for semiconductor assembly in the Tama region in Tokyo, since we were founded nearly 40 years ago. Based on our key dicing technology, we began accepting contract machining work for optical parts in the 2000s and transformed into a parts machining contract manufacturer that handles everything from electronics to optical devices. In 2014, we successfully developed the world's thinnest IR cut filter as an original TAMA Electronics product, and we continue to expand our business not only as a contract machining company, but as an electronics and optical parts manufacturer with our own line of products. We are here today thanks to your supporting our stance toward rapidly challenging new business fields and our business stance of flexibly responding to your requests. We will continue to focus all of our efforts on satisfying our customers and on carefully planning how we manage our businesses. We hope that we will continue to enjoy your trust and support.
