The PC software drives an Ocean Optics miniature spectrometer and does real time MCR (Multivariate Curve Resolution) calculations for the series of spectra. It resolves time evolving data such as chemical reaction or chromatographic data into pure constituent profiles and pure spectra. The software does this without prior information about the nature and composition of the measured mixtures. Automatic baseline correction and opacity/absorbance correction for haze solutions are standard features of the software. In RAMAN measurements the fluorescent signal component in the spectra can be eliminated, too. With the Sample/Spectrum database software the user can build up a searchable spectrum library of her/his samples or can use it for electronic documentation. The library can be searched for a given spectrum or for a given component. Chemical (sub) structure based search as well as spectral search over a sub region can be done. In self learning mode the software can be used to monitor industrial and agricultural processes with automatic alert when new component appears in the samples or a known component disappears from them. In the chemical component setup the program continuously monitors a chemical reaction and displays any change in component concentrations, including the number and spectra of the new components.

This microcontroller circuit drives an Ocean Optics miniature spectrometer via RS232 or SPI interface. Besides taking storing and transferring spectra, 8 channel digital controls are provided for precise timing of external devices, light sources. Data flow between PC and controller is done via fast RS232 interface. The controller circuit can be plug and play connected with Chemometrics and Colorimetric coprocessors.

This coprocessor circuit performs real time MCR (Multivariate Curve Resolution) calculation for a series of spectra obtained with a microcontrolled Ocean Optics spectrometer. It is just connected to the microcontroller circuit and can be used immediately. Its Small size and low power consumption makes this device ideal for field operations. The user can configure it for the necessary computations. The 8-core 32-bit CMOS microcontroller uses a 64-bit floating point numeric coprocessor in the fast calculations. The coprocessor can be set up for MCR calculation of a given number of absorption, emission or RAMAN spectra. Automatic baseline correction, opacity/absorbance correction for haze solutions and RAMAN fluorescence compensation are standard options. In RAMAN measurements the fluorescent signal component in the spectra can be eliminated, too. The Chemometrics Coprocessor circuit is configured with a PC through its RS232 interface and transfers the results using this interface, too.  In self learning mode the coprocessor can be used to monitor industrial and agricultural processes with automatic alert when new component appears in the samples or a previous component disappears from them. In off-line operation the results are stored on a 32G pen drive in FAT32 file format, which is directly readable by a PC operating under MS Windows.

The PC software drives an Ocean Optics miniature spectrometer and does real time Colorimetric calculations on the measured emission or reflection spectra. The calculations are performed using CIE standard 1 nm resolution tables. The calculated colorimetric values are the followings:

PAL, SECAM, NTSC, SMPTE and Apple RGB coordinates
CMYK coordinates
Dominant wavelength
1, 4 and 10 McAdam ellipses in the measured or in the reference point
With calibration: Light intensity (lux) in a direction at a distance
With calibration: Total flux (lum) in an integrating setup

For white sources the followings are calculated, too

The program displays and stores the measured spectrum, absorbance curve and colorimetric data. Its database system can retrieve the data by measurement id or date. The program can make statistical analysis of the measured data according to quality assurance demands.

The specially designed detector separates specular and diffuse reflections from a surface. In this way it can directly measure the light absorbance curve of the object which determines its true color. The detector automatically compensates for ambient light and it has active light sources. It is enough to place it above the measured surface without contact and the true color measurement takes only 2 seconds. The detector can measure the true color of highly reflecting surfaces, like varnished car’s paintings or lacquer paintings, too. It can quickly determine the true color of vegetables, meats and other food products.  The software that comes with the detector can resolve the spectral color components of multicolor objects after the measurement of some samples of them. From the measured spectral absorbance curve the software calculates the reflected spectrum of CIE standard illuminants (A, C, D50, D55, D65 and D75) the following colorimetric quantities:

X, Y, Z, u, v color coordinates
PAL, SECAM, NTSC, SMPTE and Apple RGB coordinates
CMYK coordinates
Dominant wavelength

The detector and the software can be used in biometrics for early warning of changes that are accompanied with the modification of color spectra of the studied biological object. Following a training period with appropriate objects it can automatically signal the presence of characteristic color change. The measured absorbance curves can be stored automatically and be studied later to identify trends of changes in the true color absorbance curves.

The compact LED tester uses a low noise, sensitive and high resolution Ocean Optics spectrometer. The holder in the 10 inch diameter integrating sphere allows the precise positioning of the tested LED sources. The LED is powered with a programmable digital power supply. The current or voltage of the LED can be precisely determined while the colorimetric measurements are taken. For larger luminaires we can develop larger integrating cavity with photometrically optimized shape. The tester can take 10 spectra/second while the LED’s current can be changed in a predefined manner. The CIE standard colorimetric calculations are performed for each spectrum, using 1 nm step tables. The tester calculates the followings:

X, Y, Z, u, v color coordinates
PAL, SECAM, NTSC, SMPTE and Apple RGB coordinates
CMYK coordinates
Dominant wavelength
1, 4 and 10 McAdam ellipses in the measured or in the reference point
Total flux (lum)

For white LEDs the followings are calculated, too

CCT Correlated Color Temperature
CRI Color Retention Index

Beside the LED’s current, voltage and light spectrum, its temperature is measured 5 times per second. In this way the colorimetric data can be analyzed in the function of temperature, as well. Measurements are stored according to type, sample No. and measurement date. For a given LED type the software can make statistical calculations according to quality assurance demands and can display GO–NO GO decisions.

The user can arbitrary select one from D50, D55, D65 and D75 standard CIE sunlight sources and the device yields an intensive, homogeneous beam with the desired spectrum. Additionally, the user can select a temperature value from the 2500K to 10000 K interval and the programmable source emits light with the spectrum of the corresponding thermal radiator. The emitted light is composed of the light of high power digitally programmed UV-VIS LED array and the average deviation of its power spectrum from the desired one is less than 10 % in the 200 nm -1025 nm interval. The light output of the LEDs can be 2500 lumen and the intensity of the beam can be set between 10 W/m2 – 120 W/m2. The spectrum of the radiated beam is continuously monitored and the instrument automatically compensates for the temperature drift of the high power LEDs. The examined device can be placed on a Peltier regulated temperature stage to measure temperature dependent behavior of it.
