Avo Photonics Selected to Package PulseTor’s SiPM-based Products

Avo Photonics, an opto-electronic service company specializing in custom design and manufacturing, has been chosen by PulseTor, Inc. to advance the performance, packaging, and production of its next generation silicon photomultiplier (SiPM) based detectors.

PulseTor’s line of SPRITETM SiPM-based detector assemblies (patent pending) are used in electron imaging applications. The measurement requirements and high-vacuum operating environment that are characteristic of these applications impose challenging thermal, electrical, material, and mechanical packaging constraints. Avo Photonics developed a high efficiency solution that supports optional low temperature operation without the use of active cooling, while simultaneously providing vacuum compatibility and minimal package size.

"The component design and system engineering converged nicely to yield a manufacturable assembly which meets PulseTor’s expectations," remarked Todd Rixman, Avo's technical manager for this program.

Dr. Nicholas Barbi, CEO of PulseTor commented, “Working with Avo was efficient and successful. They listened to our requirements and ideas and offered suggestions and improvements, all while being incredibly detailed in their analysis, design, and production. The degree of support and transparency provided by Avo were primary contributors to the success of the program.”

PulseTor ( provides high performing silicon drift detectors (SDD), SiPM electron imaging detectors, optimized preamplifiers, and digital pulse processors. Their products are designed for ease of use, providing X-ray system operation with no liquid nitrogen requirements, plug-and-play installation, and uncomplicated system upgrades.

Avo Photonics provides custom design and contract manufacturing services to customers in the military/aerospace, medical, communications, and commercial markets. Its unique pure service model assures Avo is focused on its Customer’s products. From fundamental optical physics analysis, through optical, mechanical, electrical, thermal, materials, and system design for packaging/manufacturing, into crafted Prototypes, and finally high volume Production, Avo Photonics is a one-stop shop for photonic packaging services.
