Portable spectrophotometer model of NS800 with integrating sphere 45/0 for paper printing

 

Based on large integrating sphere theory, NS800 portable spectrophotometer adopts 45/0 optical structure with 8mm aperture measurement. It is much more precise and stable than any other colorimeter model.

 


Our 3nh brand portable spectrophotometer colorimeter can specify using a universla color language and ensure suppliers are quality controlled and color managed. Plus, our SQC8 software for free make controlling color fast and easy.

 

Features:

1.  Aesthetic design perfectly combined with ergonomics structure.

2. 45/0 geometrical optics structure, comply with CIE, ISO, ASTM, DIN standard.

3. 3.5 inch large capacitive touch screen.

4. Two standard observer perspectives, multiple light sources modes, a variety of color systems.

5. The repeatability ΔE*ab is within 0.04, the errors between each instrument ΔE* ab is less than 0.2.

6. Large capacity storage, can save more than 10000 data.

7. PC software with powerful extension functions.

8. High hardware configuration with a number of innovative technologies.

9. Oversized integrating sphere, more effective homogenization ray of lights and precise measurement.

10. 15° oblique angle screen, more in line with the human eye observation.

Applications:

 

NS800 portable spectrophotometer is widely used in plastic, electronic, painting, coating, ink, textile, garment, printing and dyeing, food, medical, cosmetic, industries, scientific research institutes, schools and laboratories.  It can measure reflectance spectrum and other color index precisely. NS800 portable spectrophotometer not only can help to perform color matching and color management studies, but also can control product quality management accurately. The instrument is equipped with high-end color management software which can connect PC to achieve more extension functions.

 

Color Space

CIE LAB
-L(Lightness)-0 is black,100 is white
-a(Red-Green)-positive values are red; negative values are green and 0 is neutral
-b(Blue-Yellow)-positive values are yellow;negative values are blue abd 0 is neutral

CIE LCH
L: Lightness,value is the same in each scale C:Chroma H:Hue Angle

dE Total Color difference
Delta-E is a measurement used to indicate how much a color deviates from an accepted standards.The higher the dE, the more inaccurate the color.

 

What is CIE LAB?

CIE L*a*b* (CIELAB) is the most complete color space specified by the International Commission on Illumination (French Commission internationale de l'éclairage, hence its CIE initialism). It describes all the colors visible to the human eye and was created to serve as a device-independent model to be used as a reference.
The L*a*b* color space is used when graphics for print have to be converted from RGB to CMYK, as the L*a*b* gamut includes both the RGB and CMYK gamut. Also it is used as an interchange format between different devices as for its device independency. The space itself is a three-dimensional Real number space, that contains an infinite possible representations of colors. However, in practice, the space is usually mapped onto a three-dimensional integer space for device-independent digital representation, and for these reasons, the L*, a*, and b* values are usually absolute, with a pre-defined range.

What is Whiteness?

In colorimeter, whiteness is the degree to which a surface is white. An example of its use might be to quantitatively compare two pieces of paper which appear white viewed individually, but not when juxtaposed.
The International Commission on Illumination describes it in the following terms:
To promote uniformity of practice in the evaluation of whiteness of surface colors, it is recommended that the formula for whiteness, W2 or W10, and for tint, Tw,2 or Tw,10, given below, be used for comparisons of the whiteness of samples evaluated for CIE standard illuminant D65. The application of the formulae is restricted to samples that are called "white" commercially, that do not differ much in color, and that are measured on the same instrument at nearly the same time. Within these restrictions, the formula provide relative, but not absolute, evaluations of whiteness, that are adequate for commercial use, when employing measuring instruments having suitable modern and commercially available facilities.
