Core materials for infrared detectors: Sensitive to specific infrared bands, used to detect cold, dark celestial bodies, exoplanets, etc., and applied to infrared astronomical observations.
Large/Cryogenic mirror blanks: High rigidity, lightweight, and good thermal conductivity, maintaining shape stability at low temperatures.
High-performance diffraction gratings: Wide transmission band, good thermal stability, and radiation resistance, enabling high-efficiency, wide-band spectral dispersion.
Primary/secondary mirror substrates for extreme telescopes: With a near-zero coefficient of thermal expansion, maintaining mirror shape stability under extreme temperature differences, ensuring image sharpness.
