Marktech Optoelectronics expands SWIR sensing capabilities

Marktech Optoelectronics has announced the introduction of two large active area InGaAs PIN photodiodes, designed for expanded infrared instrumentation and monitoring capabilities.

The MTPD1346D-200 and MTPD1346D-300 are available in higher-gain active area sizes of 2.0 mm and 3.0 mm, respectively, joining existing series InGaAs PIN photodiodes with 0.1 to 1.5 mm active areas. All series models feature a 1.7 um cut-off. 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 include spectrometers, thermometers, thru-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 Marktech 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 Marktech distribution partner, Digi-Key Electronics.

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.
