Photodiode Arrays for NIR Spectroscopic Analysis

Hamamatsu Photonics (UK) introduce a new range of InGaAs photodiode arrays, the G12430 series, designed for NIR spectroscopic analysis.

Formed in a ceramic DIP, the G12430 comes in three different array sizes: 16, 32 or 46 elements. The element size on each of these sensors is large which enables high light collection along the entirety of the array; the G12430-016D offers elements measuring 0.45 x 1 mm, and the G12430-032D and G12430-046D offer an element size of 0.2 x 1 mm.

The G12430 series offers a spectral range in the NIR from 0.9 – 1.7 µm with a typical photosensitivity of 0.95 A/W under room temperature operation, so there is no need for additional cooling. These features are what make them ideal for simple measurement in NIR spectrophotometers.
