オーエムジー Product Lineup

We design and manufacture optical filter glass tailored to customer needs, such as transmission and absorption of ultraviolet, infrared, and visible light. Leveraging our in-house melting facilities, we can respond to a wide variety of requests. It is also possible to adjust the transmission rate based on composition and thickness. Depending on your preferences, we can achieve the desired characteristics by combining with deposition processing. ■ The catalog includes spectral transmission data for our standard products.

Light is a general term that encompasses visible light, ultraviolet light, and infrared light. The type of light used varies depending on the desired effect. This document explains the various differences between visible light, ultraviolet light, and infrared light, as well as the effects that can be obtained from using them. 【Some examples of applications】 ■ Sterilization and cleaning using the DNA-damaging power of 254nm light ■ Anti-counterfeiting printing and non-destructive testing using black light ■ Ultraviolet curing resin ■ Photocatalytic reaction applications using visible light ■ Scanners ■ Medical devices for cancer treatment ■ Human presence sensors ■ Infrared cameras (thermography) Manufacturing is possible from a single unit. If you have a specific application in mind, such as "I want to use this for XX, what kind of light should I use?" please feel free to consult with us! *For more details, please download the PDF or feel free to contact us.

Regular glass is known to experience a reduction in transmittance due to solarization caused by ultraviolet (UV) irradiation. However, the glass developed this time does not degrade when exposed to UV light and exhibits a negative solarization, resulting in an increase in transmittance. It is suitable for applications such as light cleaning, sterilization, printing, UV-curable resins, medical use, and analytical measurement instruments. ● For more details, please contact us or refer to the catalog.
