      Description

      Structurally “TKA-VD” consists of three functional blocks:
      – 01 “Brightness” (replaceable optoelectronic unit with a cable, input lens ø21 with an enlightened lens),
      – 02 “Illumination” (replaceable optoelectronic unit with a cable, input window with a  cylindrical cosine nozzle luxmeter  ø17),
      – a signal processing unit with a 15-pin connector for connecting a replaceable optoelectronic unit, with a keyboard and a two-line character display with backlight.
      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 coordinates of the chromaticity of the radiation source using a special program protected Certificate of official registration of the computer program No. 2003612396 .

      Also,  at the request of the customer, the  device can be produced with the following execution options: “TKA-VD” / 01 and “TKA-VD” / 02 with one of the non-replaceable unit selected by the customer without a connector.

      The optoelectronic unit of the TKA-VD spectrocolorimeter is a polychromator: the input optical radiation generated by the objective is decomposed into a spectrum on a concave diffraction grating and focused on a diode array, from which a signal is taken for further 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.

      Switching between the modes of the instrument Spectrocolorimeter “TKA-VD” on the LCD is performed in a closed cycle by pressing the “Mode” button:

      one Measurement of  luminance  L, cd / m  (or  light  E lx) and  chromaticity coordinates  (x, y) in the CIE system 31
      2 Measurement of  luminance  L, cd / m 2  (or  light  E lx) and  chromaticity coordinates  (u ‘, v’) in the CIE 76
      3 Display  color coordinates  X, Y, Z
      four Display of  correlated color temperature  T c , K

      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.

      Main advantages

      • Compactness and ease of use
      • Information output to the built-in LCD
      • There are no direct domestic analogues
      • Real-time value definitions
      • Own program for communication with PC
      • Low power consumption
      • Simplicity and ease of use
      • The optoelectronic unit contains a photometric nut (1/4 inch thread) for mounting on a tripod.

      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. Our spectrocolorimeter “TKA-VD” is suitable for measuring color coordinates and calculating the color temperature of light sources with high accuracy. This device will also be an indispensable tool when installing digital cinemas or calibrating monitors. This spectrocolorimeter “TKA-VD”, the price of which is quite low for a device of this class, is popular both in large organizations and among private clients who care about the compliance of their work or study place with the requirements of GOST.

      The device is designed to measure chromaticity coordinates and  calculate the correlated color temperature of light sources in the international colorimetric system CIE 1931. and 1976, in the plane of illumination created by normally located sources, or in the mode of measuring the brightness of self-luminous surfaces by an overhead method or the brightness of remote extended luminous surfaces and a cinema screen.

      • Spectrocolorimeter “TKA-VD” (three functional blocks).
