The L7110188 from PerkinElmer Inc is a UV-Vis-NIR Spectrophotometer that operates at a wavelength of 190 nm - 1100 nm. It has a wavelength accuracy of ± 2 nm and spectral bandwidth of 3 nm. This automatically calibrated spectrophotometer has a wavelength reproducibility of ±1 nm and scanning range of 200 nm - 950 nm. It uses a pulsed xenon lamp as an illumination source and has a split beam optical design. This spectrophotometer has a photometric range from -0.300 A to 2.500 A, linearity of ± 0.005 A (at 546 nm), and reproducibility of ± 0.003 A (up to 0.5 A) & ± 0.007 A (at 0.5 A - 1.0 A).
The L7110188 has a stray light below 0.5%, zero stability of ± 0.01 A/hour, and noise of 0.005 rms - 0.002 rms. It has a stored capacity of 90 and display size of 11.5 cm x 8.8 cm. This spectrophotometer can be controlled via a USB interface and supports Bluetooth. It has an SD card and optional printer. This spectrophotometer requires an AC supply voltage of 100 V - 250 V and consumes up to 30 VA of power. It is available in a compact package that measures 340 mm x 330 mm x 170 mm and is ideal for teaching and advanced R&D laboratory applications.
