Light Measurement

IESNA LM79 and LM-80 compliant measurement system

High accurate and instant absolute quantum efficiency measurement is possible for powder, solution and solid sample. Stray light effect in UV wavelength region is substantially eliminated. Further, high sensitivity is achieved thanks to integrating hemisphere as detector, and re-excitation elimination function enables to obtain “True property” of phosphor characteristics.

Detecting singlet oxygen (Reactive Oxygen Species（ROS))

Multipurpose spectrometer covering UV to NIR wavelength range. Shortest integration time is 5ms. Using optical fiber, various measurement optics can be configured for versatile application, including micro spot spectrum, light source, transmittance, reflectance, object color and thickness measurement.

The spectroradiometer covering very wide dynamic range of luminance level now achieves lowest noise and highest accuracy measurement using electro-cooling linear array sensor, unique spectrometry design and signal processing.

Inline evaluation system for optical characteristics of LED synchronized with control signal in production line. LE-5400 provides the optical characteristics data which are required for quality control such as OK/NG judgement and LED binning.
