CSS-45 with CSS-D Spectral radiometer sensor

Product Descriptions
CSS-45 Spectral radiometer sensor for illuminance, color, irradiance (360 nm – 830 nm), PAR and bilirubin.
Spectro radiometer sensor with outstanding light measurement characteristics.
• Individual wavelength and linearity correction guarantee precise measurements of light sources irrespective of intensity and spectral distribution.
• Mathematical bandwidth correction according to CIE 214 for accurate colorimetric measurements.
• Another unique feature of the CSS-45 is its electromechanical shutter which enables the remote-controlled dark adjustment of the sensor. This is essential for temperature-independent and long-term operation of array spectrometers.
• Diffuser with a precise cosine adjustment (f2 ≤ 1.5 %) for measuring the illuminance and irradiance of extended light sources and lighting equipment.
• Wide range of illuminance measurement from 1 lx to 350.000 lx, covering applications from emergency lighting to broad daylight conditions.

CSS-45  with CSS-D Handheld instrument for illuminance, color, irradiance (360 nm – 830 nm), PAR and bilirubin.
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.
