The CSS-45 detector incorporates a powerful microprocessor which performs not only data acquisition but also all necessary lighting calculations. Both USB 2.0 and RS 485 interfaces are standard enabling the flexible configuration of single and multi-detector based systems. An optional software development kit supports integration into third party application software.
With its wide spectral range from 360 nm to 830 nm the CSS-45 is ideal, for example, as a high accuracy photometric and colorimetric detector (according to CIE S023). The precision diffuser provides excellent cosine correction (f2 ≤ 1.5 %). The optical bandwidth correction feature (CIE 214) further improves the quality of the spectral measurement data. Manual and auto gain settings enable a wide measurement from 1 lx to 350,000 lx for illuminance and color measurements.
The embedded intelligence of the CSS-45 enables the direct output of a comprehensive range of radiometric, photometric and colorimetric parameters based on the measured spectral data.
Additionally, specialist functions are incorporated for particular applications fields including:
• Horticultural lighting – PAR measurement Photosynthetic Photon Flux Density (PPFD) in μmol/m²s.
• Human Centric Lighting – melanopic irradiance and illuminance, melanopic daylight equivalent illuminance.
• Phototherapy – total irradiance for bilirubin, Ebi, in mW/cm2 (IEC 60601-2-50) as well as average spectral irradiance in μW/cm2/nm (American Academy of Pediatrics).
Options for the CSS-45:
• Software development kit for integration of the device in the user’s own software
The robust housing and its connectors are splash proof, and therefore suitable for use in industrial applications. A variant with protective glass dome in front of the diffuser is available. A special feature of the detector is its remote-controlled shutter, which allows a dark level measurement to be made at any time.
