Thông tin sản phẩm

The apparatus consists of: -

Light Source
Light Measuring System
Control Unit

The Light Source is a gas filled tungsten filament lamp. Power for the lamp is provided by a regulated power supply housed in the Control Unit.

The Light-Measuring Device consists of: -
Achromatic system of lenses
Silicon photo-electric cell
High gain low noise amplifier

These components are housed in an assembly with a collimating lens.

The signal from the Light-Measuring Device is taken to the Control Unit, which is capable of continuously measuring relative light intensity against time as percentage transmission over the ranges to be studied. The system has a linear response with respect to transmittance and an accuracy of better than ±1.5% of the maximum reading. The Control Unit also regulates the damping of the amplifier so that the response times required to achieve 95% accuracy (T95) correspond to the specifications given in the standard.

An analogue output on the control unit of 0–1V = 100% transmission is available to be taken to a data acquisition unit. A Windows based software package is also available to enable simple data acquisition, analysis and storage via a data logger. All parameters are displayed. The versatile data logger may be used in other applications and is supplied with software that allows the data stored in the logger to be downloaded to a PC for further analysis.
