Spectrocolorimeter “TKA-VD”/01
The device consists of one 01-optoelectronic unit (input objective ø21 with a coated lens) and a signal processing unit, interconnected by a flexible multicore cable. In this case, measurements are made only of self-luminous overhead method and cinema screens in brightness mode. 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 calculate the values of the correlated color temperature in real time and measure the exact values of the coordinates of the chromaticity 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 | Measurement of luminance L, cd / m 2 and the chromaticity coordinates (x, y) in the CIE system 31 |
| 2 | Measurement of luminance L, cd / m 2 and the chromaticity coordinates (u ‘, v’) in the CIE system 76 |
| 3 | Display color coordinates X, Y, Z |
| four | Display of correlated color temperature T c , K |

One of the important aspects in the organization of labor in an enterprise, in an organization for the sale of goods or the provision of services is the measurement of conditions at the workplace, and for this, with the help of instruments, a study of the correct illumination of color design is carried out. To measure color coordinates and calculate the color temperature of light sources with good accuracy, our instrument Spectrocolorimeter “TKA-VD” is suitable. This device will also be an indispensable tool for installing digital cinemas and calibrating monitors and displays. This Spectrocolorimeter “TKA-VD” is a success both in large organizations and among private clients who care about the compliance of their work or study place with the requirements of GOST. Spectrocolorimeter “TKA-VD”, the cost of which includes verification, is useful for a variety of research conditions.
