Chalcogenide Glass Optical Window

Chalcogenide glass(IRG26) is a high-performance material for mid/far-IR windows, with 1000–14000nm(1–14μm) transmission, high refractive index, and excellent machinability. Applications include thermal imaging, security night vision, industrial thermometry, and vehicle IR detection. Scysgx uses more than 260 precision-processing machines and 65 specialist inspection instruments for closed-loop cutting, grinding, polishing, coating, and inspection. Round, square, and custom windows span 1–1000mm, in commercial and precision grades, with flatness up toλ/20. AR coatings for 3–5μm and 8–12μm provide cost-effective, stable mid/far-IR windows. Some standard versions have regular stock for rapid delivery.

Infrared thermal imaging: windows for security thermal cameras, vehicle night vision, civilian infrared detection and outdoor night-vision equipment. Industrial temperature measurement: windows for infrared thermometers and noncontact temperature detectors, meeting mid-/far-IR thermometry needs. Vehicle/security optics: windows for vehicle infrared-assisted driving and security night-vision surveillance lenses in civilian infrared applications. Research/industrial optics: windows for university-laboratory infrared spectrometers and industrial infrared inspection. Civilian infrared equipment: windows for consumer thermal cameras and portable infrared detectors, suited to mass production.

Broadband high mid-/far-IR transmission: stable, excellent infrared transmission over 1000–14000nm (1–14μm), suiting most mid-/far-IR systems. High index simplifies optics: refractive index 2.7909 reduces lens/window counts, system complexity and cost. Cost-effective, easy fabrication: precision polishing and batch processing provide economical solutions for civilian infrared equipment. Ultraprecision planar fabrication: high-precision flatness to λ/20, parallelism down to 1″ and surface quality to 10-5, without scratches or defects, ensure stable optical transmission. Full shape/specification customization: circular, square and irregular shapes with steps, slots or holes, dimensions 1–1000mm and thickness 0.15–300mm suit diverse installations. Infrared coating compatibility: 3–5μm, 8–12μm and other infrared AR coatings greatly improve transmission and reduce reflection losses. Two grades: commercial for general industrial/civilian infrared equipment and high precision for research and industrial thermometry, balancing performance and cost. IV. Core material advantages. Spectral coverage: high broadband transmission over 1000nm (near-IR)–14000nm (far-IR), a preferred mid-/far-IR material without significant absorption or scattering. Optical properties: refractive index n_d=2.7909 simplifies infrared-system design for imaging and detection. Physical properties: density 4.63g/cm³, Knoop hardness 68, moderate strength, easy ultraprecision planar polishing and controlled fabrication costs. Thermal properties: expansion coefficient 21.4×10⁻⁶/℃, softening temperature 185℃, stable optical performance for ambient- to medium-temperature industrial use. Application advantages: cost effectiveness and easy batch fabrication make it ideal for civilian infrared equipment, security night vision and vehicle infrared-system windows. V. Customization. Shapes: circular, square, rectangular and irregular, including steps, slots, through-holes and counterbores, with nonstandard sizes available. Dimensions: diameter/side length 1–1000mm, thickness 0.15–300mm, optimized tolerance grades for equipment space requirements. Surface treatment: chamfering, edge grinding, ultraclean polishing and custom cleaning for cleanrooms and special environments. Coatings: band-specific 3–5μm and 8–12μm infrared AR layers improve performance. VI. Standard coatings. Mid-IR AR: dedicated 3–5μm and 8–12μm antireflection greatly improves mid-/far-IR transmission and reduces reflection loss. DLC: improves surface hardness, contamination and scratch resistance and window life outdoors and in industry. High-laser-damage-threshold coatings improve strong-laser tolerance and protect core optics in mid-IR systems. VIII. Yasi Optical advantages. Fully controlled in-house production: closed-loop blank cutting, milling/grinding, polishing, coating, inspection, cleaning and packaging, without outsourcing and with full traceability. Precision equipment: ZYGO interferometers, precision parallelism testers, optical dimensional measuring instruments and surface-quality testers control all parameters and ensure flatness, parallelism and transmission compliance. Oversize fabrication: batch production of 1–1000mm large-aperture chalcogenide glass windows for high-end infrared systems. One-stop customization: shape, dimensions, tolerances and coatings, with optical-path adaptation support and dedicated nonstandard solutions. Two-grade delivery: commercial and high-precision grades, stable small/large-batch supply for general industrial and civilian infrared equipment. Stock and delivery: some standard products remain in stock for rapid delivery; controlled custom-order lead times meet project schedules. IX. Quality assurance. All chalcogenide glass windows undergo ZYGO interferometric flatness, precision parallelism, optical dimensional, infrared transmission and surface-quality inspections to ensure 100% compliance. Automated ultrasonic ultraclean washing and vacuum moisture-proof packaging ensure transport and long-term stability for cleanrooms and harsh environments.
