basic information
- It is the SC 504 near-infrared absorption filter and the SCM 504, which has an even sharper absorption characteristic. - It has chemical durability and moisture resistance that allow for long-term use. - It performs efficient absorption in the near-infrared range and shows high transmittance in the visible range. - It is often used when the spectral sensitivity of solid imaging devices such as CCDs and CMOS extends from the visible to the near-infrared range, especially when correcting it to normal visual sensitivity.

Company information
Japan is one of the world's leading producers of optical equipment, with optical glass being a key component. Since its establishment in 1953, SUMITA has been engaged in the world of light and glass as one of the few expert companies in this field. Since the 1960s, we have pursued our unique optical fiber technology. Additionally, we maintain a consistent production process from raw materials to final products, and there are very few companies globally that can mass-produce glass optical fibers at a scale of up to 700,000 km per month. We have earned high trust not only in the domestic market but also in overseas markets. Our optical fiber materials offer excellent cost performance and are applied in a wide range of fields, including medical devices, telecommunications, image processing, measurement, sensors, and lighting.
