How To Measure Reflectance in a Shimadzu UV-VIS Instrument Using an Integrating Sphere
This video demonstrates how to measure reflectance in your Shimadzu UV-VIS instrument using an integrating sphere.
UV-VIS-NIR Spectrophotometers
UV-2600i and UV-2700i spectrophotometers deliver the precision you need to support a wide range of applications. With their broad range of measurements, they can capture highly absorbing samples and sub-nanometer bandwidths. As a result, they are well-suited for analyzing band gaps, optical coatings, thin films and biological samples, like DNA and proteins.
With LabSolutions UV-Vis software, you can also simplify data collection, analysis and compliance. The software automatically processes data, and can easily export to Excel for further analysis. It also stores data in a secure database, complying with ER/ES regulations, that mandate safe data storage.
Wavelength Range |
185 - 900 nm 220 - 1400 nm (UV-2600i with ISR-2600Plus) |
---|---|
Photometric Range |
-5 to 5 Abs (UV-2600i) -8.5 to 8.5 (UV-2700i) |
Spectral Bandwidth |
0.1, 0.2, 0.5, 1, 2, 5 nm |
Stray Light |
0.005% or less (220 nm, NaI) (UV-2600i) 0.00005% or less (220 nm, NaI) (UV-2700i) |
The UV-2600i single monochromator with PMT can measure 185 - 900, but with the ISR-2600Plus ISR the wavelength range is expanded to 1400 with the addition of a NIR detector. The addition of the ISR improves S/N for diffusely reflecting/transmitting samples, enabling measurement of photovoltaic anti-reflective coatings and polycrystalline silicon wafers.
The UV-2600i and UV-2700i spectrophotometers use LabSolutions UV-Vis software, supporting easy analysis. This software has four measurement modes: spectral, quantitative, photometric and time-course. In addition to measurements and analysis, the software also provides judgement results. with its spectral evaluation function, it can automatically perform calculations on the data and assign a pass/fail judgment to ensure quality control standards are met.
The UV-2700i has a double monochromator that can measure ultra-low light levels. It offers more precision than standard double monochromators, which measure absorbance between 5 Abs and 6 Abs. The UV-2700i (has a larger dynamic range and) can take measurements up to 8 Abs, with a transmittance value of 0.000001% (1 part in 100 million). This precision enables you to measure low-transmittance samples, like polarization films used in LCD panels. It can also measure high-concentration samples without the need for dilution.

UV 2600/2700 UV-Vis Spectrophotometers
The UV-2600i and UV-2700i double-beam spectrophotometers are true research-grade instruments for a wide variety of applications. The high-absorbance measurement capability and sub-nanometer bandwidths make them perfect for analysis of band gap, optical coatings and thin films, biological samples like DNA and proteins, as well as for any routine work expected of a UV-Vis spectrophotometer.
