Equipment Accuracy:Star sensor lenses are core precision optical components of the attitude measurement systems for satellites and aerospace vehicles. As the optical front end of star trackers, they are specially used to capture stellar images, extract star centroids and match star catalogs in complex space lighting environments, achieving sub-arcsecond attitude determination and orientation. As indispensable "space eyes" for aerospace platforms such as modern microsatellites, launch vehicles and space stations, they provide stable, reliable and high-precision optical data support for orbital maintenance, payload pointing and interstellar navigation of vehicles.

Detailed Introduction:I. Core FunctionsCollect starlight and form high-quality images on the detector focal plane. Provide distortion-free, highly stable star centroid coordinates to support attitude calculation. Suppress stray light, sunlight and Earth albedo interference to enable all-day star observation. Provide a reference for satellite attitude control, orbit determination and laser communication pointing. II. Key Technical CharacteristicsUltra-low distortion: distortion < 0.01%, ensuring sub-pixel star positioning accuracy. High transmittance: broadband anti-reflection coating, strong capability for faint star detection. Ultra-low stray light: multi-stage light shielding, internal surface extinction and optimized diaphragms. High stability: athermal design, consistent imaging over a wide temperature range. Space-grade reliability: radiation resistance, vibration and shock resistance, long service life. Lightweight and compact: suitable for CubeSats, nano-satellites and micro-satellites. III. Typical Structure and DesignCombination of multiple spherical / aspherical lenses, mainly transmissive. Front diaphragm, large relative aperture (F/1.2–F/2.8). Wide field of view (10°–30°), balancing star acquisition speed and attitude accuracy. Space-grade optical glass, resistant to space environmental aging. IV. Application ScenariosSatellites: attitude determination for communication, remote sensing, navigation and meteorological satellites. Deep space exploration: attitude reference for lunar / Mars probes and manned spacecraft. Commercial aerospace: CubeSats, micro-nano satellites, recoverable launch vehicles. Aviation / near space: high-altitude UAVs, daytime star observation systems. V. Core ValueStar sensor lenses directly determine attitude accuracy, star detection sensitivity and environmental adaptability. They are irreplaceable core optical components for high-resolution remote sensing, space laser communication and deep space exploration missions.
