  • Product details

    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.

  • Product Information
    • Offering self-diagnosis function
    • Easily and quickly call up the information that is being measured or analyzed by registering it in you favorites.
    • Changing to the remote mode and then can link it with PC by using OPTIZEN VIEW.
    • The measurement is possible in the optimal condition by checking the equipment’s operation time, lamp warm up condition and accumulated using time in real time.
    • OPTIZEN Alpha’s login function can prevent the measured data from leaking to many and undesignated persons.
