  • Designed to comply to the highest precision standards of the automobile industry.

  • The ColorLite sd350 is a transmission spectrophotometer which measures the spectral transmission curve in 3.5 nm intervals. From this data various density values are calculated using functions stored in the software.  

  • As the complete spectral transmission characteristics are measured, various colour metric data such as the CIE L*,a*,b*-values or Y, x,y chromaticity values can be visualised.

  • Display of density values with true precise 3 positions after the decimal point.

  • The illumination is created in a high quality integrating sphere (Ulricht-Kugel) that is produced on a CNC controlled lathe from a solid aluminium block. The sphere surface then goes through a coating procedure, with the final coats made of an ideal diffuse barium sulphate powder as described in the DIN 5033.

  • By implementing the light source using an integrating sphere (as described in the DIN 4512-8) and a real grating spectrometer, the ColorLite sd350 measures the same results as elaborate laboratory equipment.

  • Variable calibration warnings for zero and D3 calibration. Warning when the calibration intervals have been reached.

  • LED Illumination source with a guaranteed minimal 20-year life span.

  • High resolution spectrometer of the ColorLite sd350 results in a highly accurate results and a superior  inter-instrument agreement.

  • By using our quality control PC software ColorDaTra emission curves for the sample film together with any light source can be calculated.

  • Scans are automatically triggered by pressing the arm downwards.

  • Trigger threshold is automatically determined during the zero calibration. This accounts for variations of the sample thickness.

  • Zero calibration to determine the offset value of the carrier materials.

  • Calibration made using a certified BAM Density 3 glass filter.

  • MSA Measurement System Analysis type 1 study passed automobile industry; Determining the repeatability (50 scans) on glass filters with values between D2 and D5.

  • MSA Measurement System Analysis type 2 study passed automobile industry; Determining the reproducibility on samples with measurements being repeated by different users.

  • PC quality-control database software available.

  • Via the USB interface measured data can be automatically uploaded to our database software - ColorDaTra - or to your own process control system.
