Marktech Optoelectronics, Inc. , a privately-held, VOSB-certified, designer and manufacturer of standard and custom optoelectronics components and assemblies, including UV, visible, near-infrared (NIR), and short-wave infrared (SWIR) emitters, detectors, InP epiwafers, and other materials, has expanded its standard Silicon photodiode offerings to include additional processes, active area sizes, case isolation and packaging options.
Marktech customers can now choose from among four unique processes to accommodate an expanded range of UV and NIR applications. These include the 365 nm UV-enhanced Series 4, for spectral ranges of 300 nm to 1100 nm, further offered in an additional 7.5 mm2 active area size; the general-purpose Series 8, for spectral ranges of 350 nm to 1100 nm; and the UV- and NIR-enhanced Series 11, for spectral ranges of 254 nm to 1100 nm. In terms of new standard mounting options, customers can now specify surface mount units for automated pick-and-place capabilities, in addition to the existing choice of TO-46 (3-pin) or TO-5 (2-pin and 3-pin) metal can package. TO-metal can packages may be further case isolated for reduced noise.
These latest additions to the Marktech standard Silicon photodiode family have been made in direct response to customer feedback, joining the also-recently introduced Silicon avalanche photodiodes and broadband PIN photodiodes. All Marktech Silicon photodiodes feature high sensitivity, low noise, and low dark current, and are both REACH and RoHS compliant. Small-to-medium sized quantities of standard Silicon photodiodes are typically available with 24-hour shipment from stock via Marktech’s longtime distribution partner, Digi-Key Electronics.
Beyond standard product, Marktech Silicon photodiodes are available with a full range of supporting NIR and point source emitters. The photodiodes and LED emitters may be supplied, either as separate stand-alone components; or, combined into a seamless, mechanically and spectrally matched package, such as a reflective switch. Most custom and hybrid designs from Marktech are available in as few as 6-8 weeks from point of prototype approval and may be produced in virtually any-sized quantity, from prototype to OEM volumes.
Typical applications for Marktech Silicon photodiodes include colorimeters, spectroscopy equipment, fluorescence, photometers, and analytical equipment, within industries such as medical, laboratory and university research, aerospace, robotics, and industrial automation.
