Single Beam UV-Visible Spectrophotometer LUS-F11 features wavelength accuracy of ±0.8 nm, ensuring that each selected wavelength closely matches its true value. It has an automatic wavelength calibration mode for precise wavelength accuracy and reliable peak positioning. The spectrophotometer includes three adjustable scanning speeds to balance scan duration and data quality. Our single beam UV-visible spectrophotometer provides a silicon photodiode detector for precise measurements without the need for high-voltage components.
