Sensor elements in optical arrays are designed for spatial measurement with multiple detection points in precise geometric arrangements, while single sensors provide only point measurements. Array elements have optimized crosstalk characteristics and uniform response across all elements.
Temperature variations affect dark current and responsivity, requiring temperature compensation circuits. Dust and contamination on optical surfaces reduce light transmission, while humidity can cause condensation affecting optical paths. Industrial-grade elements include protective coatings and hermetic sealing.
Regular cleaning of optical surfaces with approved solvents, periodic calibration against reference standards, inspection for physical damage or degradation of protective coatings, and verification of electrical connections. Most industrial elements are designed for minimal maintenance with MTBF exceeding 50,000 hours.
