Welcome to Felix Glass Material Hub, our core knowledge base for high-performance optical substrate materials.
These infrared, multi-spectral, visible and high-temperature resistant optical materials are widely machined into optical windows, domes, lenses, prisms and custom components with AR / DLC protective coatings.
Each material page covers optical properties, physical specs, fabrication capacity, coating options and typical application fields for your optical design reference.
High hardness, scratch-resistant, wide transmission range, excellent thermal and chemical stability for harsh environment optics. Popular infrared material with low absorption at CO₂ laser wavelength, ideal for thermal imaging and laser optics. Multi-spectral zinc sulfide, balanced mechanical strength and IR transmission, widely used for optical domes and windows. High refractive index infrared material, commonly used for thermal imaging lenses and infrared optical assemblies. Lightweight, low-cost IR substrate, good mechanical performance for mid-wave infrared and compact optical systems. Standard crown optical glass, excellent homogeneity, low bubble and striae, widely used for visible lenses, prisms and optical assemblies. Chinese equivalent of BK7, stable optical performance and good cost efficiency for visible windows, prisms and precision optical components. Ultra-low thermal expansion, deep UV to near IR transmission, perfect for laser, aerospace and precision optical components. We offer custom machining, high-precision polishing and optical coating (AR, DLC, anti-reflection coating) for all materials listed in this hub.
You can download material datasheets or send your optical drawing for quotation. Common finished parts: optical windows, multi-spectral domes, spherical / aspheric lenses, prisms, capillary tubes and custom blanks.Optical Material Hub
