TS7700 Benchtop Spectrophotometer
An advanced d/8° sphere spectrophotometer with simultaneous SCI/SCE measurement, a 1,000-line grating monochromator and ΔE*ab 0.02 repeatability — including fluorescent samples.
- Dual optical path — simultaneous SCI and SCE measurement, including fluorescent samples
- 1,000-line diffraction-grating monochromator with a dual 40-element silicon photodiode
- ΔE*ab 0.02 repeatability and ΔE*ab ≤ 0.15 inter-instrument agreement
- Interchangeable Φ8/10 mm (MAV) and Φ4/5 mm (SAV) apertures, plus 8° gloss measurement
The TS7700 is an advanced, portable sphere spectrophotometer with d/8° geometry (di:8°/de:8°) and a vertical housing design. A dual optical-path system enables simultaneous SCI and SCE measurement — including fluorescent samples, which is unusual for this class of instrument. A 1,000-line diffraction-grating monochromator and a dual 40-element silicon photodiode deliver high spectral resolution and ΔE*ab 0.02 repeatability.
The instrument can also determine 8° gloss, and a built-in camera preview with a crosshair indicator makes it easy to position the measurement point precisely. USB and Bluetooth 4.2 connectivity plus bundled PC software cover archiving, export and printing of results.

Applications
The TS7700 suits quality control in plastics, paint and textile production, printing, automotive components, and cosmetic and food manufacturing. Its ability to measure fluorescent samples plus the built-in 8° gloss function make it especially useful wherever a standard sphere spectrophotometer falls short.
