R9000 Standard 8° Integrating Reflectance Meter
Product Introduction
The R9000 Standard 8° Integrating Reflectance Meter is designed for reflectance testing and process quality control in photovoltaic cell manufacturing. Also known as a D8 reflectometer, integrating reflectometer, or solar cell texturing reflectance tester, it evaluates the reflectance of textured and coated solar cells.
The instrument uses diffuse illumination to excite the sample and measures reflected light at a standard 8° geometry using a spectrometer. Designed with reference to ISO 7724 and DIN 5033, the R9000 supports quality control during solar cell texturing and anti-reflective coating processes.
With a high-quality integrating sphere, a 360–1080 nm wavelength range, and rapid measurement, the R9000 helps production teams monitor surface-treatment consistency and improve inspection efficiency.

Performance Features
• Standard 8° Measurement Geometry: Designed for solar cell reflectance testing using an 8° measurement angle.
•   Wide Spectral Range: Measures reflectance across 360–1080 nm.
•   Broad Reflectance Range: Supports measurements from 0% to 100%.
• Fast Inspection: Single-point measurement takes approximately 1 second according to the technical specifications.
•   Consistent Results: Specified repeatability of 0.1%.
• Integrating Sphere Design: Supports diffuse illumination and reflectance measurement.
•   Color Measurement: Includes color measurement capability.
•  Simple Operation: Compact, straightforward design suited to photovoltaic production environments.
• Convenient Maintenance: Structure is designed to simplify servicing by technical personnel.

Working Principle
The R9000 uses diffuse illumination to illuminate the solar cell surface. Reflected light is collected and measured at an 8° angle by the integrated spectrometer. The instrument analyzes the reflected optical signal across its wavelength range to determine reflectance characteristics.
These measurements help evaluate surface texturing and coating performance, supporting process monitoring and quality control in photovoltaic manufacturing.
