The devices are designed to measure radiometric (SPEYA, SPEO) and colorimetric (chromaticity coordinates, correlated color temperature, color rendering indices) characteristics of self-luminous objects in the visible spectral region with subsequent processing, recording and printing of the information received in graphic and digital form.
The device is recommended for research at the design stage of new LED greenhouse phytolamps and for assessing the energy efficiency of a lighting device during operation.
In world practice, an agreement has been adopted that allows us to define and measure the PAR irradiance as a falling quantum flux in the range from 400 to 700 nm without involving any experimental plant reactions . For a quantitative transition from units of energy power to units of luminous power, we use a standard expression (see “Lighting measurements” by MG Kozlov, KA Tomsky, p.37).
Structurally, the spectroradiometer is made as a single unit. There is a lens on the front end cap of the body, the angle of view is 2 degrees (BRIGHTNESS mode).
Additionally, the device is equipped with a cosine corrector. The aperture of the cosine corrector is 180 degrees and eliminates a number of optical-geometric matching problems (LIGHT mode). Direct measurements in two modes.
Thanks to a careful selection of the functions used and the displayed parameters, it was possible to minimize the number of various menus and screens. The size of the displayed characters allows you to confidently read the instrument readings up to one meter.
“TKA-Spectrum” working screens
The interface part of the software (freeware) TKA_Spectr4 (@ M ‘Windows) is used to display the received data both in tabular and graphical form, to save the measurement results .
