The Aglent Technologies Cary 5000 UV-VIS-NIR spectrophotometer with innovative PbSmart technology provides an extensive wavelength scale of light absorption measurements from 175nm to 3300 nm.
Capabilities
- 175 to 3300 nm measurement range using a PbSmart NIR detector
- Scan rate in the UV-Vis: .001 to 2000 nm/min or 0.075 to 31206 cm-1/min or 0.01 to 20000 Å/min. NIR scan rate 0.004 to 8000 nm/min or 0.019 to 57142 cm-1/min and 0.04 Å to 80000 Å/min
- Beyond 8.0 absorbance units with reference beam attenuation
- Sample compartment with LockDown mechanism for quick changes and positioning for reproducible results
- Schwarzschild coupling
- Littrow monochromator
- Nitrogen pumping – separate purging in the sample and monochromator compartments
- Liquid Cell holder incorporating standard (10 mm pathlength) rectangular cell holders
- Liquid Cell holder for temperature-controlled measurements with the range 0 to 100 °C
- Solid Sample Holder with the aperture masks to allow beam collimation and measurement of small samples
- Near-Normal Specular Reflection Accessory - 8° angle of incidence with interchangeable masks for examining small samples or small areas on large samples: 3 and 6 mm in diameter
- Universal measurement accessory to measure absolute specular reflectance, transmission and scattering at different polarizations and a wide range of angles in 0.02° intervals using two-color rotating Si/InGaAs detector in a range 190-2800 nm
Applications
