CS8510 Benchtop Spectrophotometer — LED colour measurement in reflectance and transmittance
The CS8510 benchtop spectrophotometer (COLO product code PRO7910) is the LED model of the series for routine laboratory colour control: d/8 reflectance and d/0 transmittance, simultaneous SCI/SCE, an LED light source with UV and 400/420/460 nm cut-off, and a 10.5″ rotatable tablet.
Which benchtop spectrophotometer?
Overview
The CS8510 benchtop spectrophotometer measures plaques, panels, textiles, films and liquids with the full set of four aperture pairs and the transmittance test component in the standard delivery. Repeatability is ΔE*ab 0.015 and inter-instrument agreement ΔE*ab 0.15.

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 ≤ 0.015, inter-instrument agreement ΔE*ab ≤ 0.15
- 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 CS8510 benchtop spectrophotometer
Most colour checks in a laboratory are batch-to-standard comparisons repeated many times a day. The CS8510 handles them with the same optics and accessories as the other models in the series, an LED light source and a tablet interface that operators learn quickly.

Software and data

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.
