VTC 2400 Far-Field IR Emitters Testing Camera

VTC 2400 -The perfect solutions for far-field analysis of IR (Infrared) sources.

Instrument Systems VTC 2400 2D far-field infrared emitters analysis camera was specially developed for ultra-fast, precise two-dimensional analysis of INFRARED emitters. The VTC 2400 is a high-resolution infrared camera developed specially for 2D far-field analysis of the radiant intensity distribution of both 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. VTC 2400 has 2 variants that covers all typical aperture angles of IR sources. VTC 2400-100 was designed for angles up to maximum +25°; VTC 2400-200 was designed for angles of up to 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 2D image and converts by calibration the irradiance [W/m²] into the radiant intensity distribution [W/sr] of the DUTs.

Identification of the intensity maximum for laser safety evaluation

The mapping of the radiation source via an additional screen and subsequent 2D imaging by the camera make the measuring system considerably more flexible. Basic measurement parameters, e.g. distance to the DUT, angular field of view or angle resolution can be optimally adjusted to one’s own application. The measurement distance is almost freely selectable for a given viewing angle, so that minimum angular resolutions can be achieved and the DUT in the far-field (measurement distance >> DUT size) can be measured with maximum precision. This permits precise reconstruction of the radiant intensity distribution and identification of the maximum intensity (hot-spot) by the software as required, e.g. for laser safety evaluation.

This unique measurement concept guarantees a minimum error budget and results in extremely high measurement accuracy. This enables manufacturers to exploit the full performance potential of VCSELs/lasers while guaranteeing reliable operation.

Instrument Systems specifically develop the VTC 2400 for the far-field analysis of IR emitters and offer the optimum measurement solution for both laboratory and production environment.

It is particularly recommended for the analysis of VCSEL applications, including 3D sensing in smartphones (e.g. facial and object recognition) and in the automotive industry (e.g. LiDAR systems, time-of-flight).
