Marktech’s New 50mm Active Area Silicon Quad PD
[Latham, NY, November 28, 2023] – Marktech Optoelectronics, a renowned leader in optoelectronic components, is excited to announce the release of its latest innovation, the Quadrant Silicon Photodiode, part number MT03-072. This state-of-the-art photodiode meets the advanced needs of applications such as beam centering, beam nulling, position centering, beam alignment, optical tweezers, atomic force microscopes (AFMs), fine sun sensors (FSSs), and free space optical receivers.
The MT03-072 stands out in the market with its unique packaging in a hermetic TO-8 metal can. This robust packaging is expertly engineered to protect the photodiode and maintain optimal performance even in the most challenging environments. It effectively prevents the ingress of oxygen, moisture, water vapor, and other corrosive gases known to degrade semiconductor materials. These attributes make the MT03-072 exceptionally reliable and durable compared to products in standard plastic SMD or non-airtight packages.
One of the remarkable features of the MT03-072 is its non-outgassing nature in vacuum, low-pressure process chambers, or space environments due to its all-metal package containing no plastic or volatile organic compounds. This characteristic is crucial for high-precision applications where outgassing can significantly affect performance and results or damage the detector.
The MT03-072 quadrant photodiode or photodetector are made using Marktech’s proprietary Series 8 SiPD process offering a responsivity range from 350nm to 1100nm, with a peak sensitivity around 940nm to 980nm. This broad range ensures that it caters to a wide spectrum of applications, delivering high detection efficiency coupled with low noise.
For example, near infrared (NIR) laser beams with wavelengths of 800 to 980nm, 940nm, and 1064nm are commonly utilized for optical tweezing biological materials like cells, bacteria, or spores. NIR light provide a good balance between minimizing photodamage, low interference with fluorescence imaging excitation, and producing effective trapping forces. Atomic force microscopes are used to manipulate cells as well as measure surfaces at the atomic and nanoscale. These instruments utilize NIR lasers and quadrant photodiodes for precise position measurement of their cantilever or probe deflections. Marktech quad PDs are ideal for optical tweezer and atomic force microscope (AFM) applications.
Quadrant photodiodes are also used as optical receivers in free-space optical communications systems. A laser beam transmits a signal to a quadrant receiver using visible, NIR, or SWIR wavelengths. Water vapor, carbon dioxide, and other gases absorb light at specific wavelength ranges. Optical transmission bands occur between these regions of high absorption. Typical NIR laser wavelengths for free space communications include 808nm and 1064nm (Nd: YAG lasers), well within the MT03-072 photodiode specifications.
“Marktech is committed to pushing the boundaries of optoelectronic technology, and the launch of the MT03-072 is a testament to our dedication to innovation and quality,” said Vincent Forte, Chief Technology Officer (CTO) at Marktech Optoelectronics. “We are proud to offer a new product that not only meets but exceeds our customers’ expectations in terms of performance, reliability, and environmental resistance.”
The MT03-072 is now available for order and is poised to set a new standard in optoelectronic components. Marktech Optoelectronics continues demonstrating its expertise and leadership in the industry with this latest addition to its product line.
