    Chapter 2 – System Overview MS-75 S TANDARD BJECTIVE ® If your A-TAKT V-7HS was equipped with the MS-75 objective lens, it is a 75mm f/2.8 MacroSpectar lens that focuses from 1:4 magnification (at 14” from the target) to infinity. This feature allows the instrument to be focused at different distances from the sample providing the ability to change the measured spot size.

  • Page 16: Chapter - 3 Theory Of Operation

    Chapter 3 – Theory of Operation Chapter - 3 T HEORY OF PERATION The A-TAKT V-7HS are true Spectroradiometers. It collects the optical radiation (light) through the objective lens. The signal then passes through the aperture (hole) in the aperture mirror to the diffraction grating (see Figure 6).

  • Page 19 Chapter 3 – Theory of Operation Next, spectral correction factors are established using a continuous source with known intensities at each wavelength. These factors insure that the proper spectral power distribution (SPD) of the target is determined following a measurement, and that calculated values such as CIE Chromaticity, based on the measured spectral quantities, are accurately reported.

X represents the red component, Y is the green component and Z is the blue component. Y also serves as the photometric value – when using the standard MS-75 lens, Y gives candelas / meter²...
