Compact spectroradiometer CSS-45 with CSS-D

As well as spectroradiometers with integrated displays, Gigahertz-Optik manufactures spectroradiometer sensors that are separated from the operator’s handheld controller. These are more suitable for applications that require the sensor to be incorporated within some measurement system or equipment. In some situations the influence of the operator on the measured value can be reduced by the greater distance to the sensor. Sensor with fully integrated spectroradiometer function The CSS-45 is a complete spectroradiometer in a compact metal housing. With its cosine-corrected field of view, the sensor is suitable for measuring the absolute spectral irradiance without requiring any additional accessories. The sensor calculates a comprehensive range of measurement quantities from the measured spectral data. The high-quality diffuser offers a cosine-adjusted field of view with an f2 error of ≤ 1.5 %. The sensor is therefore qualified for measuring extended light sources and large area lighting devices. Compact control unit Since measurement data is processed directly in the CSS-45 sensor, the CSS-D unit is used exclusively for controlling the sensor and displaying the measured values. For this purpose, it is connected to the sensor by means of a 2 m long flexible cable. The CSS-D is equipped with a high capacity rechargeable lithium battery which also powers the sensor. The battery can be charged with common USB chargers. The color touch-screen offers a good contrast display. Alternatively, the CSS-D can be attached to a PC by a USB cable. This enables remote-control of the device.
