Spectrocolorimeter “TKA-VD”/02
The device consists of one 02 optoelectronic unit (input window with a cylindrical cosine nozzle of a luxmeter ø17) and a signal processing unit, interconnected by a flexible multicore cable. In this case, measurements are made only in the illumination mode created by normally located sources. The optoelectronic unit is a polychromator: the input optical radiation formed at the entrance slit is decomposed into a spectrum on a concave diffraction grating and focused on a diode array, from which a signal is taken for subsequent processing and calculation of the measured parameters. A device with a linear detector with a fixed position of the diffraction grating has no moving parts, which makes it possible to simultaneously record a relatively wide visible spectral region with imaging.
The device has a unique ability to determine the values of the correlated color temperature in real time and measure the exact values of the chromaticity coordinates of the radiation source using a special program protected by the Certificate of Official Registration of the Computer Program No. 2003612396 .

The device Spectrocolorimeter “TKA-VD” has the ability to display information in two ways: on the built-in LCD and dumping data via the RS-232 interface (virtual USB).
Updating the data output depends on the brightness level of the light source and takes up to 5 seconds. Switching modes to LCD is performed in a closed cycle by pressing the “ Mode ” button :
| one | Display of illumination E, lx and chromaticity coordinates (x, y) in the MKO 31 system |
| 2 | Display of illumination E, lx and chromaticity coordinates (u ‘, v’) in the MCO 76 system |
| 3 | Display color coordinates X, Y, Z |
| four | Display of correlated color temperature T c , K |
