Gigahertz-Optik debuts CSS-45 remote spectral detector

March 23, 2018

Amesbury, MA. Gigahertz-Optik GmbH has announced that its new CSS-45 packs the full power and capability of a spectroradiometer into a self-contained compact metal housing only 1.75 inches in diameter by 2 inches high. The CSS-45 covers a spectral range between 360 nm and 830 nm (extended visible spectral range according to CIE S023).

An optical bandwidth correction function based on CIE 214 further improves the quality of the measured values. Manual and auto gain settings enable a measurement range from 1 lx to 350,000 lx for illuminance and color measurements. Automatic dark-current suppression is accomplished by means of a built-in electronic shutter. Accurate illuminance measurements require a precise, cosine-corrected entrance optic. The CSS-45 has a cosine response of f2 ≤ 1 %.

The spectral detector head attaches to a PC via a one-meter-long USB cable. The USB interface handles the power requirements. Supplied software controls all measurement, data readout, and collection. An SDK is available for self-programmers.

A unique feature is the CSS-45 RS485 interface to permit fast communications with the device at longer distances for remote applications, the company said.

Every CSS-45 comes calibrated and certified by Gigahertz-Optik’s calibration laboratory that is accredited by DAkkS (D-K-15047-01-00) for spectral responsivity and spectral irradiance calibrations according to ISO/IEC 17025.

Special applications include horticultural lighting, human-centric lighting, and phototherapy.
