Vital Materials offers high-performance chalcogenide glass
(ChG) materials for infrared optical systems, supporting a wide range of
commercial and industrial applications. As a source-to-solutions provider, we
help customers integrate ChG into cost-sensitive designs that demand
scalability, precision, and optical reliability. With growing interest in
alternatives to traditional IR materials, ChG has become a compelling
option—offering comparable performance and a more efficient path to high-volume
production.
Properties
Applications and Considerations
Chalcogenide glass is an amorphous material composed of
elements such as selenium, sulfur, or tellurium, often combined with network
formers like arsenic or germanium. Unlike crystalline materials, which require
diamond turning and are more challenging to scale, ChG can be molded directly
into aspheric and complex shapes, enabling efficient, large-scale production.
Key characteristics:
·
Lower density and thermo-optic coefficient
(dn/dT)
·
Higher thermal expansion, closely aligned with
aluminum
·
Lower refractive index and greater dispersion
than crystalline counterparts
·
Maintains stable optical performance across a
broad temperature range
While ChG is not a one-to-one replacement for germanium, its
properties allow for comparable infrared system performance when optical
designs are properly tailored.
Chalcogenide glass is increasingly used in infrared optics
where cost, scalability, and production flexibility are critical. It enables
advanced optical designs in markets ranging from thermal imaging and sensing to
industrial and consumer electronics.
Design considerations:
·
Proven formulations like As₄₀Se₆₀ (e.g., VIG06)
offer consistent, scalable results
·
Not all compositions are suitable for every
application, material selection must align with system requirements
Vital Materials works closely with customers to recommend
ChG options best suited to their performance and supply chain needs. Our goal
is to ensure long-term availability and application-specific compatibility for
optical system designers.
