Spectrum Calibration Improve measurement accuracy with the new calibration feature. Place any white reflective surface in front of the camera, tap "Calibrate," and run a single reference scan. All future scans are automatically normalized against this baseline, removing brightness variations caused by the light source across different wavelengths. This results in cleaner, more consistent spectrum readings where intensity differences reflect actual material properties rather than LED output characteristics. • One-tap calibration with on-screen guidance • Calibration persists between sessions • Recalibrate or clear anytime • Visual indicator shows calibration status

• Faster scanning — Switched to continuous video capture for smoother, higher-resolution spectral measurements. • Color shift analysis — New "Shift" mode plots the reflected wavelength from the camera, enabling diffuse reflectance spectroscopy (e.g., detecting hemoglobin absorption through a fingertip). • Scan mode selector — Choose between Spectrum, Shift, or Both views with the new toggle below the plot. • Improved plot resolution — Baseline moved to use 90% of the vertical axis for better visibility of spectral features. • Analytical color rendering — Replaced lookup table with a smooth wavelength-to-RGB conversion for more accurate spectral colors. • Performance improvements — Persistent rendering context, narrower camera sampling region, and reduced audio feedback for a cleaner scanning experience.
