Model PH7290



Fixed-mount camera with RS-170 60Hz video output for wavelengths 800 nm - 2200 nm.

The PH 7290A is an infrared viewing video camera with a unique spectral response characteristic which extends from 400nm through the near-infrared to over 2 microns. Notable features include: excellent sensitivity and resolution, auto/manual gain control setting, integral optical filter slide, gen-lock input, internal shading correction, compact and lightweight.

Minimum Detectable Signal

The bench-top PH 7290A is an economical solution for laser beam profiling applications that do not require extreme precision, for example, 1-2 micron lasers (including Nd:YAG at 1.3 µm, Er:Glass at 1.5 µm and Ho:YAG at 2.1 µm). It can also be used for viewing and aligning a variety of IR sources, for thermal imaging of objects hotter than 250° C, moisture detection, forensic analysis of materials as well as semiconductor sub-surface analysis (such as Si and GaAs).

Applications


Laser beam profiling:
The bench-top PH 7290A is an economical solution for laser beam profiling applications that do not require extreme precision. The PH 7290A has become commonplace in the fiber optic and laser industry due to its high sensitivity at 1.3 and 1.55 microns and reasonable cost. Laser beams can be adjusted to impinge directly on the 9.5mm x 12.7mm (V x H) detector. Elemental resolution is limited to approximately 20 X 20 microns. The limitations of the vidicon technology confine the accuracy of the measurements to around 10%, and there can be non-linearities and shading issues with the baseline that need to be corrected for. This instrument performs quite well in near-field profiling applications where the beam is static and in the center of the detector.
