Glass Substrates

At KUPO Optics, we understand that the foundation of any exceptional optical filter lies in the quality of its glass substrate. Our commitment to excellence is reflected in our selection of superior optical-grade glass substrates, each tailored to meet the rigorous demands of various applications. Our substrates range from Borofloat and Borosilicate glasses to Sodalime and Corning Eagle XG, each offering unique properties to suit specific needs.

Our Borofloat glass, available in thicknesses from 1.1mm to 3.8mm, is renowned for its remarkable heat resistance of up to 450°C, making it an ideal choice for applications that encounter high temperatures. This glass type is characterized by its exceptional thermal shock resistance and low thermal expansion, ensuring optical integrity under fluctuating thermal conditions. In contrast, our Sodalime glass, with its range of thicknesses and a heat resistance of up to 150°C, caters to applications where lower thermal resistance is sufficient and cost-effectiveness is a priority.

For applications demanding even higher thermal stability and precision, our Borosilicate glass (D263T) offers thinner configurations while still maintaining the same high heat resistance as Borofloat glass. This makes it perfect for sophisticated optical systems where clarity and stability are paramount. Additionally, our Corning Eagle XG glass stands out with its environmental stability and absence of heavy metals, offering both thermal resilience and high optical quality.

At KUPO Optics, each glass substrate is meticulously chosen to ensure the highest quality and performance of our optical filters. Whether it's for high-temperature environments, precision optical instruments, or consumer electronics, our substrates provide the reliability and optical excellence our clients expect. This dedication to quality and versatility in our substrate selection underscores our role as leaders in the field of optical filtering and wavelength control.
