Take inventory of system characteristics of surface photovoltage

Motorized Rotation Stage Manufacturer shares that it is well known that surface photovoltage is the photogenic voltage effect of solid surface and is the result of photoinduced electron transition. The surface photovoltage technique is an excellent way to study the characteristic parameters of semiconductor. Below small make up to tell you about the main characteristics of the surface photovoltage system

Surface photovoltage modularization design, stick to the user demand, flexible economy, widely applicable, upgrading, transformation and maintenance are convenient optional high-power halogen tungsten lamp and high-power xenon lamp light source, also can use existing patent or specified source spectral system, ensure good wavelength accuracy and repeatability, eliminate the influence of multistage spectrum and stray light small ultra weak signal processing ability, improve the signal-to-noise ratio, choice of many patent rack for accuracy, convenient clamping, electrode contact good, little interference to the weak signal testing.

Independent research and development of high performance weak signal processor, and can carry all the automatic control and signal switch: full automatic dedicated system software to integrate spectral system, multistage spectrum filter device, the weak signal processing system of parameter Settings and selection, automatic scanning, signal amplification and A/D, data acquisition and data processing, graphics file to automatically generate and display A variety of format of the data and images more groups of data backup and print function contrast function automatically remove bulky error, system error, linear error, automatic calibration cycle error, T.
