CS4560 Portable Spectrophotometer — 45/0, LED and UV, two apertures
The CS4560 portable spectrophotometer (COLO product code PRO7964) measures colour and colour difference with 45/0 geometry — 45° ring illumination and 0° viewing. A full-spectrum LED with UV light source, two switchable apertures (Ø8 and Ø4 mm) and the best repeatability of the series serve paints, inks, printed matter, plastics and textiles, and the instrument also measures traffic-sign colours.
Which 45/0 portable model?
Overview
The CS4560 is the most accurate model of the CS45 series. The UV source can be included or excluded for fluorescent and optically brightened samples, the Ø4 mm aperture reaches small areas, and the traffic-sign function shows brightness factor and chromaticity against standard sign colours.

Key characteristics
- 45/0 geometry with 45° ring illumination
- Full-spectrum LED and UV light source, 400–700 nm
- Two switchable apertures: Ø8 mm (MAV) and Ø4 mm (SAV)
- Repeatability ΔE*ab ≤ 0.03, inter-instrument agreement ΔE*ab ≤ 0.15
- Traffic-sign function: brightness factor, chromaticity, polygon tolerances
- USB and Bluetooth, 1 000 standards and 30 000 samples
Suitable for
- Traffic signs, road markings and retroreflective films
- Paints, coatings, inks and printed material
- Plastic parts and plaques, textiles, leather and paper
- Colour quality control with CIE Lab (D65/10°) and ΔE pass/fail in the laboratory, at the line or at goods receipt
Why this instrument
45/0 measures colour as it is seen, including the effect of gloss — the right choice when the result must agree with visual assessment of prints, paints and coated parts. The CS4560 adds UV for fluorescent materials and a second aperture for small areas in one portable instrument.

Software and data

The PC software (free download) stores standards with their tolerances, shows the spectrum and the colour difference, follows trends and exports results for reports. Standards can also be created and measured directly on the instrument.
Data are transferred by USB or Bluetooth.
Standard delivery

Optional: micro printer, powder test box, universal test component, locating plate. The delivered configuration for a specific order is the one confirmed in the COLO.Science quotation.
Knowledge base
New to colour measurement? Light sources, metamerism, CIE Lab, ΔE and measuring geometries (45/0 and d/8) are explained on COLO.Science, our knowledge base.
Selection guide
- Traffic signs, road markings, reflective films or coarse surfaces: CS4580 — Ø20 mm, UV, Bluetooth.
- Highest accuracy, fluorescent samples, large and small areas: CS4560 — UV, Ø8 and Ø4 mm, Bluetooth.
- Routine Lab and ΔE checks of non-fluorescent samples: CS4510 — one aperture Ø8, Ø4 or Ø2 mm, USB.
- Results independent of gloss (SCI) or glossy and textured samples: d/8 geometry — the CS30 portable series.
- Transmittance, liquids or haze: a benchtop spectrophotometer is needed — see the CS60 series.
