Tokyo Opto-Electronics Co., Ltd.

We are a laser application device manufacturer that has a track record both in Japan and overseas.

Our company designs and manufactures laser application devices. Our main products are non-contact outer diameter measurement instruments and mirror cooling dew-point hygrometers. We also offer a roller measurement system that features our Laser Micro Gauge system, and computer-based measurement systems for measuring high-temperature thermal expansion of ceramics and metals. Our Laser Micro Gauge system is used for measuring thermal expansion in high-temperature (2400 °C) or radiation environments, and it is mentioned in the Japanese Industrial Standards (JIS). We have many dealings with Canon, Ricoh, Konica Minolta, Fuji Xerox, and other major Japanese companies. We have done business with overseas companies in China, Korea, Vietnam, and Malaysia.

[Company strength]
Our company is a long-established manufacturer that offers high-precision, non-contact dimension measuring instruments and optical dew-point hygrometers. We have been responding to requests from university research institutions and major manufacturers for 45 years since our establishment. We have enhanced precision and developed solutions for difficult-to-measure situations, thereby contributing to the JIS standards (two in heat expansion measurement, and another two in moisture measurement). Customer requests are highly appreciated in our company, and shared among the sales representatives and engineers. The mechanical, electrical, and software engineers in our company incorporate the request into the measurement instrument before making a proposal if necessary, however difficult it may be for other companies. We also excel at application systems that feature our measurement devices. Our roller measurement system is one example of this. We manufacture these systems on a made-to-order basis. We have many returning customers who have been using our products and systems for a long time. We try to keep records and a history for each customer, and offer repair service as long as parts are available, even for 20- to 30-year-old products. 

[Business description]
Our main product lines are Laser Micro Gauge non-contact measuring instruments, DPH mirror cooling dew-point hygrometers, and roller measurement systems used to measure the outer diameter and run-out of rollers. Our roller measurement systems are products that apply our Laser Micro Gauge system. Our company has been engaged in designing and manufacturing laser application devices for 45 years since our establishment. We have responded to requests from university research institutions, OA equipment manufacturers, and metal working manufacturers. We developed our Laser Micro Gauge system for high-temperature objects and radiation environments. We design and manufacture systems that contain jigs and software necessary for measuring the outer diameter and dimensions of plate widths and special wires. We also manufacture polychromators. We develop, manufacture, and sell high-temperature thermal expansion measurement equipment as computer-based measurement systems (including computer software) for ceramics and metals. These products make use of our Laser Micro Gauge system for high-temperature objects. 


[Strength of products/technologies]
We developed original measurement methods and high-speed scan types to cope with high-temperature objects. These have realized high precision in any measuring environment. Examples are provided below.
(1) Our high-temperature measurement type is used to measure thermal expansion, and is mentioned in JIS standards (e.g., JIS R 2207-1).
(2) It can be used in environments where fire, high-temperature light-emitting objects, and other sources of optical noise are present. These are usually difficult to measure with optical measurement instruments.
(3) Our product scans 3600 times per second, which is the world’s highest level among laser scan type instruments. It also measures at short intervals with enhanced repeat accuracy. This includes measuring wire with an outer diameter of less than 10 mm in units of microns at 0.46 m intervals on a line at 100 m per minute.
Our roller measurement system is a product that applies our high-temperature measurement system. It can also measure outer diameter, vibration, and straightness of various rods. This is why it has been adopted by many major OA equipment manufacturers and rubber roller manufacturers. 

[Representative's message]
Our company has offered a wide range of optical products to be of value to society ever since its establishment. Our main products have proven to be popular among customers. This includes our roller measurement systems with our Laser Micro Gauge built-in, and optical dew-point hygrometers, which measure humidity with light. We also embarked on 3D measurement, inner diameter measurement, and other new measurement fields by working with other companies. We have conducted demonstrations and measurement experiments on new objects in recent years in the context of new requirements for parts to have higher precision and diversity. These processes led us to discover new applications and functions for our measurement instruments, and we sensed the possibilities in new markets. We will continue to develop new systems to cultivate new markets. This will be done through our development experience in roller measurement systems. We will also improve our existing measurement instruments while enhancing their performance and reliability even further. 

[Company structure for market development/overseas expansion]
Our domestic sales contacts are the headquarters sales department and Kansai branch office. We do not have an overseas sales office, but all of us including both sales representatives and engineers are trying to respond to inquiries from other countries. Our response can be in English or Japanese. All indications on our products and operating instructions are written in English for exports. We have senior executives visit overseas locations a few times a year for promotions, technical meetings, and technical guidance. This is mainly done by the president. Our products are exported to China and Singapore through sales agents in Taiwan and Malaysia, and also to Korea, Vietnam, Thailand, the Philippines, and the US through Japanese trading companies. We recently productized a non-contact outer diameter measurement instrument using high-precision measurement technologies for metal wire and rollers. This product can conduct 2-asis measurement simultaneously, which is effective for cultivating these markets. We will expand our lineup to include measurement instruments for medical and optical communications parts. 

[Market share/Ranking]
Our automatic roller measurement system has the largest share of the market. Our non-contact outer diameter measurement instrument appears to be in third place in the industry (Keyence is first, and Mitutoyo is second). 

[Awards and media coverage]

Nikkan Kogyo Shimbun, our 2-axis Laser Micro Gauge appeared in an article as a 2-directional measurement method (November 25, 2014). 

Some of our laser device products are FDA certified.
