BVF (Back-illuminated, fringe-suppressed)

*Strengths - High quantum efficiency (QE) with excellent sensitivity in low-light and near-infrared (NIR) regions

*Weaknesses - Fringe patterns may occur in the NIR region above 750 nm, potentially introducing noise into the analysis 
 

Measurement of weak Raman/PL signals in the near-infrared (NIR) region (e.g., biological samples, NIR Raman)

OE (Open Electrode)

*Strengths - Stable baseline with no fringe patterns in the NIR region

*Weaknesses - Lower quantum efficiency compared to BVF, with reduced sensitivity in UV and NIR regions 
 

Suitable for strong Raman or PL signals in the visible range (e.g., polymers, inorganic materials), especially where baseline stability is critical

Bio (Cells, Tissues)

*Recommended Laser Wavelength(s) - 785 nm (low fluorescence), 633 nm (alternative)

*Criteria for Wavelength Selection - Minimizes fluorescence background in biological samples

SERS (Surface-Enhanced Raman)

*Recommended Laser Wavelength(s) - 532 nm (strong enhancement), 633 nm (less heating)

*Criteria for Wavelength Selection - 532 nm and 633 nm enhance Raman signals through resonance with metallic nanostructures

Material Science (Polymers, Semiconductors)

*Recommended Laser Wavelength(s) - 532 nm, 488 nm (good resolution)

*Criteria for Wavelength Selection - High Raman intensity with low fluorescence leads to efficient signal acquisition

Carbon Materials (Graphene, CNT)

*Recommended Laser Wavelength(s) - 532 nm, 633 nm (Raman efficiency vs fluorescence trade-off)

*Criteria for Wavelength Selection - Balances between strong Raman scattering and moderate fluorescence

PL Measurement (Quantum Dots, Semiconductors)

*Recommended Laser Wavelength(s) - 325 nm (for UV excitation), 488 nm (common for visible-range PL)

*Criteria for Wavelength Selection - This wavelength range efficiently excites electronic transitions, with shorter wavelengths offering higher PL efficiency and wider measurement bandwidth.
