Marktech expands SWIR sensing capabilities with new large-active-area InGaAs PIN photodiodes

Marktech Optoelectronics Inc of Latham, NY, USA, a privately held designer and manufacturer of standard and custom optoelectronics components and assemblies – including UV, visible, near-infrared (NIR) and short-wave infrared (SWIR) emitters, detectors, indium phosphide (InP) epiwafers and other materials – has launched two large-active-area indium gallium arsenide (InGaAs) PIN photodiodes designed specifically for expanded infrared instrumentation and monitoring capabilities.

The new Models MTPD1346D-200 and MTPD1346D-300 are available in higher-gain active-area sizes of 2.0mm and 3.0mm, respectively, joining existing series InGaAs PIN photodiodes with 0.1-1.5mm active areas. All series models feature a 1.7μm cutoff wavelength. In addition, all large-active-area Marktech InGaAs PIN photodiodes offer increased light sensitivity, uniform response, low dark current, and identical wide spectral response ranges.

Typical applications for Marktech large-active-area InGaAs PIN photodiodes include spectrometers, thermometers, through-water detection and chemical analysis. Available accessories for the Models MTPD1346D-200 and MTPD1346D-300 include a full range of SWIR range emitters, all of which can be spectrally and mechanically matched to the InGaAs PIN photodiodes within a single, contact package. Units are also both REACH and RoHS compliant.

Small-to-medium-sized volumes of standard Models MTPD1346D-200 and MTPD1346D-300 are available with 24-hour shipment from stock via distribution partner Digi-Key Electronics Corp. In addition, alternate package and sorting options, as well as custom and hybrid designs, may be produced in as few as 6-8 weeks from the point of customer prototype approval.
