Characteristics of the array spectrometer ST1818

1. Silicon photodiode array (18 double-row) sensors

The larger array sensor, the stronger light will not be saturated, the lower light sensitivity is higher and the wider spectrum response range, has guaranteed the instrument measurement speed, the accuracy, the stability and the consistency, grasps the core technology, with the same platform of international standards, achieve perfect compatibility.

2,Adopt full waveband balanced LED light source

The array spectrometer ST1818 adopts 400 ~ 700nm full waveband balanced LED light source as the illumination light source, which has enough spectrum distribution in the visible light range and avoids the loss of the spectrum of white LED in the specific wave band.

3,Grating splitting technology

The use of plane grating spectroscopy technology, with a higher resolution, so that more accurate color measurement.

4,Intelligent base, automatic calibration

It is equipped with intelligent calibration base, can carry out automatic white board calibration, professional grade standard white board reflectivity R% ≥95% , good surface uniformity, high stability, can obtain repeated accurate data.

5,New fashion appearance design based on ergonomics

The hand-held position and the position of the measuring button are carefully designed to meet different holding habits, smooth and fine surface, derived from the professional appearance treatment technology.

6,Excellent interstation and repeatability

The repeatability ΔE * ab ≤0.038, the Inter-instrument Error ΔE * AB ≤0.38 data is stable and reliable, which ensures the consistency of the data measured by multiple devices, and can be used for color matching and accurate color transfer.

7,Multi-color measurement space and observation light source

Provide CIE LAB, XYZ, Yxy, LCH, Cie Luv, s-RGB, HunterLab, βxy, DIN Lab99 Munsell (C/2) color space, and a variety of observation light sources
