LEDUSBEthernet

Product Summary
The CL-700A illuminance spectrophotometer provides high-speed, high-accuracy measurement of illuminance, chromaticity, spectral power distribution and color quality metrics across a wide wavelength range (360–1,000 nm). It is designed for evaluation of LEDs, OLEDs, optical systems, image sensors, cameras, AR/VR devices and horticulture lighting, and for integration into production and inspection environments.

Product Overview
Combining Konica Minolta optical measurement expertise with compact, portable design, the CL-700A delivers stable, repeatable results from very low to high brightness levels. It supports handheld operation, fixed-station integration and synchronized multi-point measurement (up to 15 units). The instrument pairs with CL-S30 software for intuitive control, real-time visualization and efficient data management.
