Vigo Catalog 2018/2019 - 4

I am very pleased to introduce the 2018 edition of VIGO System product catalog for infrared (IR) detectors and dedicated electronics. VIGO System has been providing infrared detectors to the market for many years; VIGO IR detectors are used in various applications where reliability and the highest technical performance are required. Our products have unique performance and operating parameters thanks to close coordination of research, development and production, as well as cooperation with renowned research centers around the world. 2017 was unique for VIGO System as we celebrated our 30th...

VIGO System S.A. was founded in 1987 by a group of specialists in the field of photon infrared detectors. VIGO System owns a unique technology that enables the production of devices for very fast, sensitive detection of infrared radiation in the range of 1 - 16 μm, operating at ambient temperature or cooled with maintenance-free thermoelectric coolers (TEC). Our manufacturing capabilities begin with growth of epitaxial HgCdTe or InAsSb wafers by MBE or MOCVD. We deposit metal contacts by thermal evaporation and do full photolithography, dicing, assembly and packaging in our facilities. Over...

Infrared detectors HgCdTe, photoconductive, photoelectromagnetic and photovoltaic detectors are optimized for operation at any wavelength within the wide spectral range 1-16μm, reaching fundamental BLIP limits and operating within 190 – 300K temperature range without cryocooling. The detectors are characterized by high detectivity and excellent speed of response. We are able to adapt to your needs and also create unique one- and multi-element detectors designed for a specific application.

2.1 Photoconductive detectors Infrared detectors Photoconductive detectors PC PC series features room temperature and TE cooled IR photoconductive detectors. The devices are optimized for the maximum performance at opt . Cut-on wavelength is limited by GaAs transmittance (~0.9 Jm). Bias is needed to operate photocurrent. Performance at low frequencies (<20 kHz) is reduced due to 1/f noise. The highest performance and stability are achieved by application of variable gap HgCdTe semiconductor, optimized doping and sophisticated surface processing. * Other optimal wavelengths available upon...

2.2. Photovoltaic detectors Infrared detectors Photovoltaic detectors PV PV series features room temperature and TE cooled IR photovoltaic detectors. The devices are optimized for the maximum performance at X . Cut-on wavelength can be optimized upon request. Reverse bias may significantly increase speed of response and dynamic range. It results also in improved performance at high frequencies, but 1/f noise that appears in biased devices may reduce performance at low frequencies. Highest performance and stability are achieved by application of variable gap HgCdTesemiconductor, optimized...
