Encapsulated PbS Detectors and Arrays

These PbS infrared detectors and arrays have a unique encapsulation that gives you special features:

• Robust and stable so it can be directly mounted on your PCB
• Longer lifetime and highest detectivity at room temperature
• Small footprint through new thin-film encapsulation
• Bondable contacts
• Compatible with industry standard production methods
• The high sensitivity of PbS
• High quality is built into the manufacturing process and inspection

PbS Detector Options
Pbs Chips (Bare SMD Chips)
Line Arrays (1 – 512 Pixels)

Single Pixel Bare Chip Detectors

trinamiX bare chip infrared detectors are protected by a thin-film encapsulation. They can be directly wire-bonded to printed circuit boards. Bare chip solutions enable small, flexible and very efficient devices.

• Bare chip
• New encapsulation technology (patent pending)
• Fully wire bondable
• Readily available in large scale

Multi Pixel Array Detectors

Multi-Pixel detectors consist of 2 to 16 pixels in line or matrix design. The detectors cover a wide spectral range, which is highly relevant for applications in inline or mobile process analytics, quality control and gas sensing.

• PbS and PbSe Multi-Pixel detector for wavelengths from 1 to 5 µm
• Pixel numbers from 2 to 16 possible in variable designs
• Highest detectivity at room temperature compared to standard technology
• High stability and long lifetime through thin-film encapsulation

Line Arrays

The arrays are available in a pitch starting from 50 µm. Further customization is possible. Due to their unique thin-film encapsulation they can be directly wire-bonded to printed circuit boards.

• High stability and long lifetime through thin-film encapsulation
• PbS detector for wavelengths from 1 to 3 µm
• Detectivity at room temperature above 1 ∙1011 cm·Hz½/W.
• Readily available in large scale.

The array modules comprise a 256 pixel PbS array (1-3 µm) and a corresponding read-out electronic in a hermetic PS28 package.

• Frame rates up to 1 kHz
• Thermo electric temperature stabilization
• Analog multiplex output.
• AR-coated sapphire window for optimal transmittance in accepted wavelength range

Thanks to their low power consumption, trinamiX array modules are the ideal solution for mobile applications such as handheld spectrometers.
