LS178 Small Aperture Spectrophotometer

The LS177 Spectrocolorimeter is a benchtop spectral color measurement instrument with a 50 mm large measuring aperture, designed for accurate color evaluation, spectral reflectance analysis, and color difference comparison of non-transparent materials such as powders, masterbatches, plastics, textiles, painted surfaces, food products, and more.

🔍 Key Features

🟡 Large 50 mm Aperture

• 50 mm measurement aperture captures a wide area of the sample — especially beneficial for rough, uneven, or particulate surfaces where smaller apertures may give inconsistent readings.

📈 Spectral Reflectance Curves

• Provides professional spectral reflectance curves that go beyond basic tristimulus values, helping you analyze hue, saturation, brightness and subtle material characteristics.

📊 Rich Color Data & Color Spaces

• Supports multiple color spaces:

  • CIE Lab, Luv, LCh, Yxy

  • CMYK, RGB

  • Whiteness and yellowness indices like WI-98, WI-Hunter, YI-98, WI-R457

  • Spectral reflectance data

• Offers a full set of color difference formulas including ΔEab, ΔEuv, ΔE94, ΔEcmc (various weighting), and ΔE*00.

🧪 Robust QC & Comparison Tools

• Built-in quality control (QC) function allows you to set color difference thresholds and automatically judges pass/fail results.

• Electronic color charts are included internally for quick color matching (typically ~90% match accuracy).

💻 Connectivity & Software Support

• Connects via USB and Bluetooth to mobile APP and PC software to support data export, report generation, and statistical analysis.

📱 Touchscreen Interface

• Equipped with a 7-inch IPS color touchscreen for intuitive, standalone operation without needing external devices.

📊 Technical Specifications

🛠 Typical Applications
