Hioki Motors has launched a blue-violet laser-specific sensor "light sensor 9743". Used in combination with the company's optical power meter to measure the luminous intensity of blue-violet lasers. It is mainly used for laser head detection of a new generation of optical discs using blue-violet lasers.
Since the wavelength sensitivity characteristic near 405 nm is stable, the measurement can be stably performed even if the wavelength of the measurement object is uneven. In addition, since the reflectance is lowered, it is also possible to detect the laser head of a new-generation optical disc having a large incident angle of light on the light receiving surface of the sensor.
There are two types of hand-held "9743" and separate "9743-10", the price is 84,000 yen.
