The SSIVT is a complete electrical current-voltage measurement system used to characterize photovoltaic cell performance. This current-voltage tester works by sampling current at different voltages of the photovoltaic cell with a variable impedance load.

This IV measurement system has a separate terminal interface for voltage and current measurements. Each IV curve dataset is saved as a separate ASCII text file.

This I-V Testing Measurement System has a 4 wire Kelvin configuration to remove the resistance effects of the leads and bias the cell at specific voltages.

The I-V Measurement System SSIVT-T20C includes:

A) Keithly Model 2450 - Touchscreen
.Power: 20 W
.Max Voltage: 200V
.Current Range: 1A

B) Sciencetech's SciPV-IV Software for Windows-based control.
.Windows 7/10 32/64 bit

C) RS232 to USB dongle

The SSIVT-2KC works with all Sciencetech Steady State Solar Simulators.

Compatible with Steady State (Continuous) Solar Simulators only.

The 9030DS consists of two 100 mm scanning monochromators placed in series in subtractive mode. Bandpass is determined by the width of an intermediate slit, but the 9030DS has a net output dispersion of zero because the monochromators are optically coupled so that the dispersion of the second grating cancels that of the first. This leads to homogenized wavelengths at the output port - there is no spectrum, only a single undispersed slit image - which allows the unit to act as a tunable bandpass or notch filter.

Stray light of all sorts is drastically reduced in a double monochromator, and in the 9030DS it is further minimized by the use of concave holographic gratings. It is ideal for applications where stray light is a problem - where there may be a strong scattered background, such as in spectroradiometry, Raman or UV measurements of solar radiation.

The 9030DS can be used as a tunable notch filter to remove one particular wavelength while allowing all others over the bandpass to pass through, making it an ideal instrument to pre-filter out the strong laser excitation wavelength in a Fluorescence or Raman system so that the weaker output signals can be observed.

The 9030DS is a fully integrated unit with the two diffraction gratings coupled mechanically for accurate positioning, adjusted manually using a thumb-wheel. A variety of fixed slit widths is available. It can be upgraded to be motorized and controlled by a computer with the 9030 Motorized Upgrade. Only one motor and drive unit is required for both monochromators, enabling control via Sciencetech Sci-Mono Active-X library or full featured Sci-Spec software.

The Model 9030DS can also be used to pass or filter out several selected wavelengths by using a custom intermediate multi-slit mask instead of a single width intermediate slit. Mirror coatings have been chosen for this model to enhance performance in the UV-VIS region. Please contact a Sciencetech Applications Specialist for such custom wavelength filtering.

The 9030DA double additive monochromator consists of two 9030 monochromators placed in series. Stray light is drastically reduced in a double monochromator, and in the 9030DA it is further minimized by the use of concave holographic gratings. The inbound light is dispersed by the first grating and again by the second. Both gratings rotate simultaneously in the same direction, and in the DA the monochromators are coupled so that the dispersion is double that of a single 9030 monochromator. Bandpass is half of the corresponding 9030 monochromator for the same output slit, and resolution using a 100 µm slit is 0.4 nm.
Mirror coatings have been chosen for this model to enhance performance in the UV-VIS region.

The Sciencetech 9030 monochromator is a compact, single grating, scanning monochromator with 100 mm focal length (both output and input). It has a manual wavelength selector dial with an optional external motor drive for computerized control. The compact design is made possible by its Seya-Namioka optical layout, using a single holographic concave grating and f/3.2 aperture. A pair of removable fixed-width slits are included for the input and output ports. Several removable fixed slit width sizes are available to choose from ranging from 100 μm to 3 mm width. Additional removable slits and custom width slits can also be purchased separately.
Mirror coatings have been chosen for this model to enhance performance in the UV-VIS region.
There are 5 grating choices (sold separately) covering from UV to near-IR; choose a UV to VIS range to pair with the UV-VIS mirror coatings on this model. The 9030 monochromator cannot be used as a spectrograph and therefore only accepts single channel and PMT detectors at its output port. However, it can be used as an excitation wavelength tunable light source.
The 9030 is Sciencetech's most economical monochromator with a manual control wavelength selector and removable, fixed-width slits. The input and output ports are purposely placed optically in-line, making it a simple addition to a straight line beam in an optical system. Being a scanning monochromator, it does not have a flat output field and hence cannot be operated as a spectrograph with a multi-channel detector mounted at the output port.
