Description



Precision N-BK7 Ar-coating Optical Hemispherical Dome Lens For Sun Light Sensor



1. Material & Construction

  • Optical Substrate: Schott N-BK7 borosilicate glass (Grade A homogeneity)

  • Geometry: True hemispherical dome (180° field of view)

  • Coating: Broadband AR coating (300–2500nm, >98.5% avg. transmission)

  • Sealing: Hermetic edge bonding for IP68-rated environmental protection


2. Critical Properties

  • Spectral Performance:

    • 90% transmission from 350–2000nm (uncoated)

    • <0.2% reflection loss per surface (coated)

  • Environmental Durability:

    • Thermal cycling: -50°C to +150°C operational range

    • UV degradation: <0.1%/year @ 1000 W/m² solar exposure

  • Optical Precision:

    • Surface accuracy: λ/8 @ 632.8nm

    • Refractive index homogeneity: <5 × 10⁻⁶


3. Core Functions

  • Omnidirectional Light Capture: 180° FOV for accurate solar irradiance measurement

  • Optical Path Preservation: Maintains collimation through curved interface

  • Environmental Shielding: Protects sensors from rain/dust while minimizing Fresnel losses

  • Calibration Stability: Near-zero angular dependence (±0.5% responsivity variance)


4. Key Applications

  • Solar Monitoring Systems:

    • Pyranometers & pyrheliometers (ISO 9060 compliant)

    • PV panel efficiency sensors

  • Meteorological Stations:

    • Daylight harvesting sensors

    • UV index monitors

  • Aerospace Instruments:

    • Satellite solar flux detectors

    • Rover environmental sensors

  • Agricultural Tech:

    • Photosynthetically active radiation (PAR) sensors
