Infrared light, powerful through precision. IR LED quality defines the limit of intelligent sensing. Infrared technology is widely used in security surveillance, face recognition, optical communication, medical devices, automotive LiDAR, gesture control and more. The invisible nature of IR LEDs means testing cannot rely on the human eye—precise instruments must quantify radiant power, peak wavelength, centroid wavelength, spectral FWHM, luminous intensity, radiant intensity angular distribution and other key parameters to ensure product radiation efficiency, consistency and reliability.

Core equipment: integrating sphere with spectroradiometer for total radiant power and spectrum; DPS-500 high-precision DC source for accurate constant current and voltage measurement; SPM-8000IR spectroradiometer optimized for near-infrared (900-1650 nm, extensible to 1700 nm+); GMS-136 goniophotometer with IR detector for radiant intensity angular distribution by rotational scan. Covers single LEDs to modules and luminaires, lab R&D to production line, light distribution QC to 3D sensing module testing.

Key Features

• High accuracy: NIST/PTB traceable; <0.5% deviation vs. reference LED
• Wide band: 900-1650 nm standard, extendable to 1700 nm+
• Pulse measurement: μs-level pulse drive and sync; transient capture without self-heating
• Flexible: modular design; single LED to module/luminaire
• Automation: one-click operation, automatic report generation
