MCH Instruments Co.,Ltd.
Is a measurement apparatus capable of visually depicting regular changes in electrical activity, such as an electrical current or signal. The resulting data appears as a waveform drawn on a graph with two axes, where the horizontal X axis represents time and the vertical Y axis indicates voltage. In addition, the luminance of the waveform itself is often referred to as the Z axis, which demonstrates the intensity of the activity measured.

Instrument Systems Optische Messtechnik GmbH
A photometer is used to measure the photometric quantities of illuminance (lx), luminous intensity (cd), luminous flux (lm), and luminance (cd/m²). The integral method and the fast response time of silicon photodiodes means that photometers can achieve an outstanding measuring speed. They are therefore ideal for performing fast goniophotometric measurements. We take great care in the development and production of photometer heads and use innovative amplifier technologies.

PIMACS CO., LTD.
A goniophotometer is a system to measure the luminous intensity of the source (or illuminance from the source at a given distance) in many different directions from the source. Compared with the sphere method, the goniophotometer method is theoretically free from errors due to differences in intensity distribution of the light source under test. It is applicable to acquire the luminous intensity distribution, luminous flux, spatial color distribution, and luminance distribution of lamps and luminaires.
