UV/Vis Spectrophotometry
Instrumentation Available:
- Lambda 1050 UV/Vis Spectrometer: Spectral range of 175 nm to 3300 nm (Double beam instrument)
- Lambda 365 UV/Vis Spectrometer: Spectral range of 190 nm to 1100 nm (Double beam instrument)
Several accessories are available for the Lambda 1050:
Three Detector Module:
The Three Detector Module covers a wavelength range of 175–3300 nm. The detector module has a photomultiplier tube (PMT) detector for the UV/Vis range, and an indium gallium arsenide (InGaAs) detector and a lead sulfide (PbS) detector for the near infra-red (NIR) range. The detector module comes as standard in the Lambda 1050 spectrometer and is available as an upgrade to the NIR high-performance Lambda instruments
Universal Reflectance Accessory:
The Universal Reflectance Accessory (URA) is a variable angle specular reflectance measuring module that loads directly into the detector compartment The detector compartment is fully interchangeable with other sampling modules and can be quickly replaced by a different module such as an integrating sphere, if required. The URA can be used to collect absolute or relative reflectance measurements with an angle of incidence in the range 8°–65° and utilizing wavelengths in the range 3100–190 nm (3100–185 nm with N2 purge). Samples are placed on the horizontal sample plate and can range in size from 8 mm to greater than 150 mm. Samples with sizes between 3 mm and 8 mm could be measured using a custom-made sample holder. It is also possible to collect transmittance and absorbance measurements when the URA is installed. Samples should be placed in the sample compartment to collect these measurements.
Integrating Sphere:
The 150 mm Integrating Sphere accessory is available for use with the high-performance Lambda 1050 spectrometer. The sphere accessory is a diffuse reflectance accessory that loads directly into the detector compartment of the Lambda 1050 spectrometer. The integrating sphere device expands the measurement capability of the instrument to include total and diffuse reflectance of both specular and diffuse samples.
