Component Specifications

Definition
A receiver lens is a critical optical component in optical positioning sensors that captures incoming light signals (typically from a laser or LED source) and focuses them onto a photodetector or sensor array. It optimizes light collection efficiency, minimizes aberrations, and ensures precise signal detection for applications requiring high-accuracy position tracking, distance measurement, or alignment in industrial automation and manufacturing systems.
Working Principle
Operates on the principles of geometric optics, using precisely curved surfaces (spherical or aspherical) to refract and converge incoming light rays onto a focal point. The lens material and coating are engineered to maximize transmission of specific wavelengths while reducing reflections, scattering, and optical distortions, enabling the sensor to detect minute variations in light intensity or position for precise measurements.
Materials
Optical-grade glass (e.g., BK7, fused silica) or engineered polymers (e.g., PMMA, polycarbonate) with anti-reflective coatings (e.g., MgF2, multilayer dielectric) for wavelengths typically in visible to near-infrared ranges (400-1100 nm).
Technical Parameters
  • Coating Broadband AR coating (400-700 nm or 700-1100 nm)
  • Diameter 5-25 mm
  • Focal Length 10-50 mm
