2D far-field analysis of infrared emitters Fast testing of IR emitters in the far-field range with the highest measurement accuracy The VTC 2400 is a high-resolution infrared-camera that was developed specially for 2D-far-field analysis of the radiant intensity distribution of VCSELs and IR emitters. The measurement system consists of a light-permeable screen and a monochrome camera specialized for measurements in the near infrared range. With its two standard versions, the VTC 2400 covers all typical aperture angles of IR sources: the VTC 2400-100 was designed for angles up to maximum ± 25°; the VTC 2400-200 for angles of maximum ± 60°. Thanks to the light-shielding camera housing, the system is suitable for use both in the lab and in production applications. Ultra-fast radiation profiling in the far-field The measuring system is constructed in such a way that the radiation source (DUT) irradiates a light-permeable, diffusely scattering screen, where its typical spatial radiation properties are visible. On the other side of the screen the infrared camera VTC 2400 captures this two-dimensional image and converts by calibration the irradiance [W/m2] into the radiant intensity distribution [W/sr] of the DUTs.
