Description
1. Service Overview
With nearly 20 years of experience in laser and optics, Sunpump offers professional sample testing services based on our own platforms: laser ultrasound, LBIC, ultrafast transient absorption/fluorescence spectroscopy, low-wavenumber Raman, LIBS and micro-imaging spectroscopy. Customized testing plans are provided per customer requirement, with complete data and analysis delivered.
2. Testing Capabilities
Laser Ultrasound: non-contact NDT for internal defects, thickness, stress and coating.
LBIC: light-beam-induced-current imaging for photovoltaic/semiconductor characterization.
Ultrafast Transient Absorption: femtosecond time-resolved spectroscopy for carrier dynamics and excited-state studies.
Ultrafast Transient Fluorescence: time-resolved fluorescence lifetime measurement.
Low-wavenumber Raman: down to 5 cm⁻¹ with ultra-narrowband notch filters.
LIBS: rapid elemental analysis for solids and liquids.
Micro-imaging Spectroscopy: micro-region composition and structure analysis.
3. Service Process
1) Requirements discussion; 2) Sample delivery; 3) Testing and data acquisition; 4) Report with spectra and analysis.
4. Applications
