UV-Vis Spectrophotometer double-beam type OPTIZEN™ Alpha, OPTIZEN™ Alpha UV-Vis Spectrophotometer double-beam type
The luxuriously designed OPTIZEN Alpha is spectrophotometer to use double-beam method.
OPTIZEN Alpha can grasp the quantitative characteristics such as density or purity by measuring transmittance or optical density according to wavelength of sample in the range of ultraviolet rays and visible ray.
OPTIZEN SERIES can be utilized from not only a general analysis experiment to but also a specialized research field and guarantee accurate measurement and excellent reproducibility, accordingly offer reliable results in the various fields such as environment, biotechnology, chemistry, etc.

The previous single beam type spectrophotometer has a weak point of error occurrence in measuring a sample, because of the movement of a light source by time lag in measuring the strength of between a reference light and a light from sample.
To solve the problem, OPTIZEN Alpha was designed as a double-beam type spectrophotometer.
The system utilizes an additional reference beam to improve the measurement performance by compensating the intensity fluctuation of its light source.
