Infrared Temperature-Measurement Window

Infrared thermometry windows protect noncontact temperature-measurement, thermal-imaging, and high-temperature online-monitoring systems. Designed for 2–14μm mid/far-IR thermometry, high-transmission IR crystals provide temperature and impact resistance, sealed dust protection, and high IR transmission in hot, dusty, corrosive, or high-pressure industrial environments. Scysgx supplies germanium, silicon, zinc selenide, zinc sulfide, chalcogenide glass, and calcium/barium fluoride windows. Round, square, and custom shapes, integrated sealing structures, and 1–1000mm sizes support furnaces, electrical inspections, petrochemicals/metallurgy, HVAC, and security thermometry. Some standard versions are stocked for rapid delivery.

Industrial high-temperature monitoring: online infrared thermometry windows for industrial furnaces, kilns, heat-treatment equipment and high-temperature piping.

Security/vehicles: windows for security infrared thermometers, vehicle infrared-assisted thermometry and outdoor temperature equipment. Research/medicine: windows for precision laboratory thermometry, medical infrared thermal imaging and noninvasive temperature measurement.

Dedicated high transmission for infrared thermometry: core mid-/far-IR thermometry band 2–14μm, transmission ≥90% after coating, and no infrared absorption loss ensure temperature accuracy. High-temperature/deformation resistance: excellent thermal stability over -40℃–1500℃, without optical deformation or coating cracking at high temperatures. Industrial protection: high hardness, impact resistance and resistance to dust, water vapor and acid/alkali corrosion for harsh outdoor, industrial-furnace and high-pressure environments. Integrated sealing: custom flange seals and waterproof/dustproof structures support stable long-term online industrial thermometry. Ultraprecision optical fabrication: flatness to λ/20, surface quality 60-40, no scratches or scattering and no interference with infrared thermometry signals. Flexible materials: germanium, silicon, zinc selenide and zinc sulfide selected to balance performance and cost. Full specification customization: circular, square, irregular, flanged, stepped and perforated shapes for diverse infrared temperature probes. IV. Material selection for infrared thermometry. Germanium (Ge): high transmission throughout 2–14μm, high index and a preferred general-industrial thermometry material for most equipment. Silicon (Si): 1.2–7μm mid-IR transmission, high hardness and wear resistance, preferred for high-temperature furnaces and industrial monitoring. Zinc selenide (ZnSe): broadband 0.6–18μm transmission, 10.6μm laser compatibility and dual use for precision/laser thermometry. Zinc sulfide (ZnS): broadband 0.4–12μm transmission and strong environmental adaptability, preferred for outdoor/vehicle thermometry. Chalcogenide glass (IRG26): 1–14μm infrared transmission and cost effectiveness, preferred for civilian/mass-produced thermometry equipment. Calcium/barium fluoride (CaF₂/BaF₂): UV/IR dual-band transmission for low-temperature/research-grade precision thermometry. V. Customization. Shapes: circular, square, rectangular and irregular, including flanges, steps, slots, holes and counterbores. Structures: single optical windows, integrated flange-sealed windows and high-pressure sealed thermometry windows. Dimensions: diameter/side length 1–1000mm, thickness 0.15–300mm, tolerances optimized as required. Coatings: infrared AR, wear-resistant DLC, broadband AR and high-laser-damage-threshold layers. Mounting: threaded, snap-fit, flange and other methods. VI. Standard coatings. Mid-IR thermometry AR: dedicated 3–5μm, 8–12μm and 2–14μm bands, transmission ≥90%. DLC: improves hardness, contamination/scratch resistance and industrial service life. Broadband AR: full-band 2–14μm for multiband infrared thermometry. High-laser-damage coatings: improve strong-laser resistance in laser-assisted infrared thermometry. VIII. Yasi Optical advantages. Materials for all applications: one-stop supply of all specialized infrared-thermometry materials, selected as needed without multisource procurement. Custom sealing: industrial sealed windows address protection under high temperature, pressure and dust. Fully controlled in-house closed-loop cutting → polishing → coating → seal fabrication → quality inspection, with full traceability. Precision equipment: ZYGO interferometers, infrared-transmission testers and optical dimensional instruments for comprehensive quality control. Stock/custom supply: standard sizes stocked, with rapid customized delivery of nonstandard sealed windows. Thermometry accuracy: low-scattering, high-transmission optics prevent window-induced errors. IX. Quality assurance. All infrared thermometry windows undergo infrared transmission, precision flatness, dimensional-tolerance, high-temperature and sealing inspections to ensure accurate industrial thermometry and reliable protection. Ultraclean washing and moisture-/shock-proof packaging support shipping and long-term industrial use.
