UV–VIS–NIR Scanning Photospectrometer – Multi-Sample Analyzer

واجهة ثنائية اللغة • يدعم ملفات CSV/Excel/TXT • تحليل α و Eg (Tauc) • T%(E) و dT/dE(E) و Urbach(Eu) • PDF إنجليزي فقط.

Auto-delimiter (Tab/Comma/Semicolon/Space/Pipe) • Cleans non-numeric/comment rows.
Multiple files supported
Converted to cm internally.
Used if A/T% columns are missing.
Smart–Adaptive: selects the linear part of Tauc if left blank.
Auto uses the lowest 15% of the energy span.

A or T% vs λ (nm)

α vs E (eV)

Tauc Plot (αhν)^n vs E (eV)

T% vs E (eV)

dT/dE vs E (eV)

Urbach Plot: ln(α) vs E (eV)
