XenICs has introduced the XLIN 1.7/2.2/2.5 series of InGaAs linear photodiode arrays. They are available as a hybrid assembly of photodiodes integrated with a charge-amplifying multiplexer, or ready-mounted into the compact and rigid XenICs XEVA-LIN digital camera.
The new XLIN series have high sensitivity, linearity and uniformity, as well as good stability and a wide dynamic range. They come with three pixel counts: 128, 256 or 512, and have a wavelength response up to 2.5µm with a read-out rate of more than 9,000 lines per second.
The new XenICs XLIN arrays are hermetically sealed in a standard flat bottom package with a coated anti-reflection window and extending fixation flanges. This ensures an optimum thermal coupling of the device. The built-in multiplexer, along with thermo-electric coolers (TE1, TE2 or TE3) reduce the dark current and noise of the array and enable longer integration times. Four integration capacitors (0.1 to 16pF) can be selected.
The XLIN arrays enable thermal imaging of hot objects in the 200°C to 800°C range. They are suitable for near infrared spectroscopy and inspection in industrial production lines and agriculture.
