Double monochromator UV-2700

Performance with a Minimum

8-Abs Photometric Range

Equipped with a double monochromator that achieves ultra-low stray light levels, the

UV-2700 is optimal for measuring low transmittance samples, such as polarization films

used for LCD panels. The UV-2700 is capable of 8-Abs measurements, and can make

accurate transmittance measurements to 1 part in 100 million, accommodating a variety

of sample measurements.

Sample Polarization Film Measurement UV-2700

Equipped with Shimadzu's Proprietary

Lo-Ray-Ligh Grade Diffraction Grating

Shimadzu's proprietary Lo-Ray-Ligh grade diffraction

grating enables the high precision of the UV-2700. In the

diffraction grating production process, new proprietary

manufacturing methods have been developed for

Shimadzu's holographic technology. By optimizing the

etching process, we have successfully manufactured

extremely low stray light diffraction gratings while

maintaining high efficiency. With this a newly designed

optical system equipped with a

double Lo-Ray-Ligh

monochromator, the UV-2700

achieves unparalleled

ultra-low stray light levels.

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.
