3nh 45/0 Spectrophotometers 

The 45/0 geometry spectrophotometer measures color by illuminating the sample at a 45-degree angle and capturing the reflected light at 0 degrees, perpendicular to the sample. This setup closely mimics how human eyes perceive color, making it ideal for evaluating the color as it appears in real-world conditions.  In a “fixed geometry” or “single angle” device, the first number is the starting point of the light, and the second number is where the light ends up after the reflection off the surface of the sample. In a 45:0, the light source is set at 45-degrees and the detectors are set directly overhead at 0-degrees.

When to Use 45/0 measurement: 

  • Smooth and Matte Surfaces: Particularly suitable for smooth and matte surfaces, where surface texture and gloss do not significantly affect the color perception.

  • Packaging and Printed Materials: Often used in industries where the final appearance to the consumer is critical, such as packaging and printed media.

  • Color Quality Control: Suitable for quality control in environments where visual consistency is key, ensuring that the product looks as intended under standard viewing conditions.


Translation for Color Measurement on Smooth Surfaces

For color measurement exclusively on smooth object surfaces, a color difference meter with a 45°/0° or 0°/45° geometry can be selected. This angular configuration most closely mimics the way the human eye perceives objects; therefore, the color information it measures aligns most closely with human visual observations. 

For instance, in color inspection scenarios involving flat plastic products, smooth metal sheets, and similar smooth surfaces, a 45°/0° or 0°/45° color difference meter can quickly provide highly accurate color data.

FAQs About YS4580 Spectrophotometer

Colorimeters or spectrophotometers are used to measure liquid color. They measure light coming through or reflecting off the liquid. Readings can be reported as Lab*, RGB, or absorbance units. So that objective color analysis can be used to control quality, or to measure chemical concentration.

D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries. 

True color in chemistry is the color seen in a solution or compound in standardized conditions. It depends on electronic transitions in molecules, specifically absorption of a particular wavelength of light, and this depends on the structure of the compound.

A colorimeter is sufficient for basic, routine color checks, while a spectrophotometer is needed for precise, comprehensive color analysis—here’s the clear breakdown:

When a Colorimeter is Sufficient

  1. Simple color matching needs: Ideal for checking if a sample matches a predefined standard (e.g., basic paint batches, plastic parts with solid colors).

  2. Consistent lighting conditions: Works well when measurements are done under fixed, standard light sources (no need to account for varied light effects).

  3. Cost-sensitive, high-volume tasks: Perfect for production lines requiring fast, low-cost color checks without advanced data analysis.

When to Use a Spectrophotometer

  1. Precise color quantification: Necessary for measuring Lab values (lightness, red-green, yellow-blue axes) or detecting subtle color deviations (critical for automotive coatings, high-end textiles).

  2. Complex color analysis: Required for metallic/pearlescent finishes, transparent materials, or samples with gloss/texture variations.

  3. Compliance and documentation: Essential when precise color data (spectral curves) is needed for quality audits, regulatory compliance, or brand color standardization.


To answer this question, you first need to clarify your specific needs: 

  • Is it for simple color quality control (QC)?

  • To coordinate with supply chain color management?

  • To monitor on-line color stability?

  • Do you require computer color matching or production color correction?

  • What is your budget?

  • Systematic supervision and evaluation of color performance in dyed products?

If you aren’t fully clear about your requirements at the initial stage, our color management engineers are ready to communicate with you. We will recommend solutions tailored to your needs. When conditions permit, we can provide prototype demonstrations and trial testing to ensure the instrument meets your practical application requirements.
