OTSU, Japan — Nippon Electric Glass Co., Ltd. (NEG) (TOKYO: 5214), a global leader in specialty glass headquartered in Otsu, Japan, announced that its IR Transmitting Glass (chalcogenide glass) “FI-02” has been adopted for Heimann Sensor GmbH’s wide-angle lens unit for thermal cameras. The lens unit achieves a 120° × 68° field of view, surpassing the previous product’s maximum of 92° × 59°. The adoption marks a significant milestone for FI-02 and showcases how advanced specialty glass can meet the demanding optical and manufacturing requirements of the expanding infrared sensing market.

Thermal cameras detect infrared radiation emitted by people or objects and convert it into thermal images. Infrared sensors can detect the locations of people and temperature distributions. They are expected to be used for people detection and monitoring, where privacy considerations are important, and for air-conditioning control, while their use is expanding in healthcare, equipment monitoring, and security.

Advanced Glass for Wide-Angle Thermal Imaging
Article content
Lenses for infrared sensors must meet various requirements, including infrared transmittance, suitability for mass production, and optical performance that enables a wide field of view. FI-02 combines high infrared transmittance with a high refractive index, making it highly suitable for wide-angle lens design. It is also suitable for mass production through press molding. Heimann Sensor evaluated these features and adopted FI-02.
