VIGO Photonics Affordable MWIR Detection Module

VIGO Photonics has introduced the smallest, eco-friendly MWIR detection modules available on the market. The modules feature overall chip dimensions of 10 mm x 10 mm x 3 mm.

The cost-effective detection modules have been built using InAsSb semiconductor material, meaning that cadmium or mercury are not used, thus leading to a RoHS-compliant device.

The low-cost MWIR InAsSb detection module AM03120-01 is an 'all-in-one' uncooled IR detection module that comes in a compact TO8 package. A photovoltaic multiple-junction InAsSb detector element is directly combined with a low-noise preamplifier. Amplified analog output may be directly linked to the measurement equipment. It is possible to carry out through-hole mounting.

The detection module features an anti-reflection coated window that avoids unnecessary interferences. The end product can be provided as an OEM component (just PCB with detector element), fitted on a TO8 submount or mounted and sealed in a TO8 package with a window.

Key Features of the Product

VIGO Photonics technological potentials enable the production of indium arsenide antimonide (InAsSb) detectors, with the advanced techniques of Molecular Beam Epitaxy (MBE).

Cost-effective detection modules are designed specifically for applications in which it is crucial to ensure a higher resistance to harsh operating conditions. InAsSb modules comply with the RoHS directive, implying that the products guarantee the consumer market safety. The reasonable price is a powerful benefit together with materials of highest quality.

The following features make the modules user-friendly:

  • Compact size
  • Signal already amplified, voltage output
  • Available on a standard submount (TO8)
  • Available for directly mounting onto user’s PCB (OEM version)

The AM03120-01, a cost-effective MWIR InAsSb detection module, comes with three options. AM03120 is a detector available in the TO8 package. AM03110 is a detector that comes on a steel base. Users can also order a miniaturized chip, measuring 10 mm x 10 mm x 3 mm, with an amplifier on the PCB – AM03100.

The cost-effective detection module can be used for several applications. Thanks to its high-speed response, it is appropriate for applications when MWIR fast pulse laser carries data, for instance, MWIR spectroscopy. The affordable module has been designed specifically for low-power and space-limited applications.

Since the need for a built-in trans-impedance preamplifier is avoided in customer application, space is saved. It offers an additional advantage of low power consumption suitable for battery-operated devices.

Listed below are the other applications:

  • Laser metrology
  • Laser power tracking and control
  • Monitoring industrial and laboratory processes

The device has been developed particularly to offer new features: thermoelectric cooling, digital output, etc.
