Double monochromator UV-2700i

Measures Slight Differences in

Absorbance

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.
