The functionality of the UV-2700i / 2600i can be freely expanded to suit the measurement objective. By accommodating a wealth of accessories, the system can address any user’s applications and a variety of situations. Thanks to intuitive operations, anyone can easily obtain the data required.
A key feature of the UV-2600i single monochromator system is its measurement wavelength range. By using the optional ISR-2600Plus Integrating Sphere attachment, the measurement wavelength range can be extended from 220 nm to 1400 nm, significantly expanding its applications.
Integrating Sphere Enables Measurements to 1400 nm
The UV-2600i is also equipped with Shimadzu's proprietary Lo-Ray-Ligh grade diffraction grating, which achieves high efficiency and low stray light levels. By installing the ISR-2600Plus two-detector integrating sphere, the 300 nm to 1100 nm wavelength range of conventional models can be extended to 1400 nm. In addition, the UV-2600i achieves a significant noise reduction, and can accommodate measurements of solar cell anti-reflective films and polycrystalline silicon wafers.
Equipped with a double monochromator that achieves ultra-low stray light levels, the UV-2700i is optimal for measuring low transmittance samples, such as polarization films used for LCD panels. The UV-2700i is capable of 8-Abs measurements, and can make accurate transmittance measurements to 1 part in 100 million, accommodating a variety of sample measurements.
Achieves Ultra-Low Stray Light, Enabling 8-Abs Measurements
In the case of a device equipped with a general double monochromator, the absorbance that can be covered is about 5 to 6, but the UV-2700i offers a range to 8 Abs, with a transmittance value of 0.000001 % (1 part in 100 million). This system achieves high-level absorbance measurements with incomparable precision. In addition to measuring even high-concentration samples as is, eliminating the need to dilute samples, the system can be applied to evaluating the transmission characteristics of polarization films. Wavelengths in the 400 nm to 650 nm range can be measured to 8 Abs.
Sample Polarization Film Measurement
With the rotating film holder (photograph below), two film samples can be set on the same optical axis. In this example, the polarization film is rotated in the plane, and the transmittance is measured when the film transmits and blocks light.
The new spectrophotometer with the LabSolutions UV-Vis software which achieves labor-saving measurement provide a more convenient analytical environment.
