ColorLite Densitometer sd350 transmission densitometer
The ColorLite Densitometer sd350 was developed to meet the high precision requirements of the automotive industry. It measures the density values of product colours, such as plastic films, and combines high measurement quality with ease of use.
2-channel system for a high dynamic range
The sd350 uses a 2-channel system to give a high dynamic range. Depending on the density of the film, it measures with two separate measurement technologies and recognises automatically which one to use.
Transmission spectrophotometer with a real grating spectrometer
The sd350 measures the spectral transmission curve in 3.5 nm intervals and calculates density values as well as colorimetric data such as CIE L*a*b* or Yxy. A real grating spectrometer with more than 100 sampling points in the visible range gives results comparable to laboratory equipment, and density values are shown with three decimal places.
Solid aluminium integrating sphere
The integrating sphere is produced on a CNC lathe from a solid aluminium block and provides ideal diffuse illumination. The built-in LED light source has a lifespan of more than 20 years. The sd350 is made in Germany.
Calibration and verified measurement system
Zero calibration with an open path determines the offset value of the carrier material, and the trigger threshold is set automatically during zero calibration. Calibration is done with a certified BAM density 3 glass filter, and variable warnings remind the user when zero and D3 calibration are due. The sd350 has passed MSA type 1 and type 2 measurement system analysis studies for the automotive industry.
Options and accessories
As an option the sd350 can also measure in 45°/0° reflection. Accessories include coloured and grey filters, a Schott colour filter set, 6 mm and 2 mm apertures and the PC software ColorDaTra.
