CS8520 Benchtop Spectrophotometer — LED with UV and tightened tolerances, d/8 and d/0

The CS8520 benchtop spectrophotometer (COLO product code PRO7911) measures reflectance and transmittance colour and haze with an LED light source with UV and 400/420/460 nm cut-off, a 154 mm integrating sphere and simultaneous SCI/SCE. It is the LED model with tightened tolerances: repeatability ΔE*ab 0.014 and inter-instrument agreement ΔE*ab 0.14.

Overview

The CS8520 benchtop spectrophotometer has the same optics, apertures and tablet operation as the CS8510, with tighter repeatability and inter-instrument agreement. It suits laboratories that work with an LED source and need closer agreement between several instruments without moving to xenon light.

CS8520 benchtop spectrophotometer with LED light source and 10.5-inch tablet

Key characteristics

  • Reflectance d/8 and transmittance d/0, SCI and SCE measured simultaneously
  • LED light source with UV, 400/420/460 nm UV cut-off, 360–780 nm
  • Repeatability ΔE*ab ≤ 0.014, inter-instrument agreement ΔE*ab ≤ 0.14
  • Reflectance apertures Ø25.4/30, 15/18, 8/10 and 4/6 mm, recognised automatically
  • Haze per ASTM D1003, more than 40 indices, 41 illuminants
  • 10.5″ rotatable tablet, built-in camera, USB and Bluetooth

Suitable for

  • Opaque and translucent plastic plaques, masterbatch and compounds
  • Paints, coatings, inks and pigments; textiles and paper
  • Films, sheets and glass in transmittance; liquids in cuvettes
  • Colour quality control with CIE Lab (D65/10°) and ΔE pass/fail

Why the CS8520 benchtop spectrophotometer

Several instruments in one company — laboratory, production and incoming inspection — only help if they report the same numbers. With inter-instrument agreement of ΔE*ab 0.14 the CS8520 narrows the difference between units, so tolerances can be set once and used on every instrument.

Reflectance, transmittance and sample handling

Reflectance port

Reflectance portSample holder presses opaque plaques, panels and textiles against the d/8 port; the built-in camera shows the measured spot.

Software and data

Colour measurement PC software

The PC software stores standards with their tolerances, shows the spectrum, the colour plot and the colour difference, and exports results for reports and archiving. Quality-control and sample modes are also available directly on the 10.5″ tablet, and the built-in camera shows the measured spot.

Reflectance and transmittance results are kept in the same database, so one standard can be checked in both modes.

Standard delivery

  • Instrument with white calibration board and black calibration cavity
  • Reflectance apertures Ø25.4, 15, 8 and 4 mm and sample holder
  • Transmittance test component, cuvette and transmission black baffle
  • 10.5″ tablet, PC software, USB cable, power adapter, user guide

Optional: Ø4 mm transmittance test clamp, inversion component, culture dish, film fixture, custom apertures. The delivered configuration for a specific order is the one confirmed in the COLO.Science quotation.

Selection guide

  • Closest tolerances, reference instrument: CS8560 — xenon and LED, ΔE*ab ≤ 0.01 repeatability and ≤ 0.1 between instruments.
  • LED source with closer agreement between several instruments: CS8520 — ΔE*ab ≤ 0.14 between instruments.
  • Routine laboratory colour control with LED: CS8510.
  • Xenon light for fluorescent and optically brightened samples at the entry price: CS8500.
  • Transmittance or haze: all four models — the transmittance test component is included.
  • Compact benchtop instrument with a built-in 7″ screen: the CS60 series (CS6080, CS6060, CS6020, CS6010).
  • Large or curved parts at the production line: a portable spectrophotometer is the better tool — ask us for the right model.
