EQUIPMENT / FACILITIES

HITACHI U-3900H UV-VIS SPECTROMETER

A high-performance double-beam UV-Vis spectrophotometer for precise optical characterization across the 190–1100 nm range.

How It Works / Principle

  • Operates on the principle of light absorption and transmission, where a monochromatic beam passes through a sample and a reference.
  • Measures absorbance and transmittance to study electronic transitions of molecules and materials.
  • The double-beam system compensates for light source fluctuations and improves baseline stability.

Key Features / Advantages

  • High resolution and photometric accuracy.
  • Double-beam design for stable, reproducible measurements.
  • Measure absorbance, transmittance, or reflectance for both thin film and liquid samples.
  • Reliable baseline correction and low stray light.

Applications

    • Optical characterization of organic, inorganic, and hybrid nanomaterials.
    • Thin-film absorbance and transmittance studies.
    • Analysis of solution-phase samples (e.g., perovskites, polymers).
    • Fundamental studies in photophysics, photochemistry, and material science.
