Well-equipped facilities that underpin the reliability of 150,000 lenses produced per month
We possess cutting-edge manufacturing equipment and high-precision inspection devices for optical lens production.
With these, we realize strict quality control and stable product supply, and provide high-precision optical lenses.
-
Polishing line We have over 80 polishing machines installed, enabling us to handle optical lens production of 100,000 to 150,000 units per month. We possess equipment capable of accommodating a wide variety of products and shapes. We also place strong emphasis on processing accuracy in order to meet strict quality standards, and supply high-quality lenses on a stable basis.
-
Ultrasonic cleaners As we prioritize environmental protection, we employ spindle-drying ultrasonic cleaners. These enables us to clean and dry products without the use of organic solvents (alcohol). Through successes in ensuring stable quality and mitigating the burden on the environment, we are working towards achieving a sustainable manufacturing environment.
-
High-precision evaporator This dedicated device is capable of processing ultra-wide band anti-reflection and high-reflection low-scattering metal mirrors (Al, and AgAg). Our proprietary control software allows us to maintain stable coating accuracy. Additionally, we possess a UH 4150, Cary 6000 i, and USPM RU W, which enable us to evaluate optical characteristics in fine wavelength ranges. With these, we are realizing the supply of higher-precision products.
-
Eccentricity
measuring machineThis eccentricity measuring machine by Trioptics makes precise eccentricity measurement possible, achieving stable product performance and provides high reliability particularly for products that require precision.
-
Inspection devices With three ZYGO interferometers installed, we have a strict quality control system in place. By measuring minute surface irregularities and optical errors with a high degree of precision, we guarantee product accuracy that meets the advanced needs of our customers.
-
Joint verification
spaceWith three laboratories in place, we can respond quickly to customer design projects, such as by incorporating or correcting optical lenses immediately after we have manufactured them. We have prepared an environment that allows us to smoothly check product quality for the purpose of making final adjustments to prototypes and products in development. In turn, this allows us to flexibly respond to customer requests immediately.
Initiatives geared towards passing on optical glass skills and developing young employees
In manufacturing optical glass, passing on skills is an essential initiative for developing the industry and improving product quality. Skills that have been passed down from generation to generation, which have been honed over time by skilled engineers based on years of experience and knowledge, are passed on through education and training for their successors. This makes the manufacture of products requiring outstanding optical performance and the supply of stable quality possible.
Additionally, to enhance various forms of technical prowess, we also focus on obtaining national qualifications and technical certifications. Every year, we are seeing an increasing number of employees with these qualifications. Through these initiatives, we are succeeding in improving our technical prowess and stabilizing our product precision, and are building a firmer technical foundation by developing the next generation of engineers.

Wastewater management that underpins sustainable production activities
As part of our ESG (Environment, Society and Governance) initiatives, we have installed wastewater treatment facilities and wastewater purification equipment at our factory through which we perform thorough wastewater purification. We are endeavoring to minimize the impact of wastewater generated at our factory on the environment and to preserve the water quality in the surrounding area. Through these efforts, we are realizing sustainable production activities and facilitating harmony with the local community and natural environment.
