Daily inspection for near-infrared light sources at wavelengths 850nm, 940nm, and 1050nm.
This is a luminance meter primarily used to measure the wavelength of infrared light sources. Measurements are taken by placing the light-receiving part on the surface of light source. The backlight display and measurement result hold function improve work efficiency. It also supports external communication and allows for data output (USB compliant). Additionally, it can be powered by either two AA batteries for portability or an AC adapter. It is a compact and lightweight measuring device weighing approximately 300g. It can be used for auto-calibration (self-calibration) with our company's light source box. Furthermore, it has the capability to correct differences compared to other companies' luminance meters.
