Company Overview

SensL offers a range of Silicon Photomultipliers, SPAD Arrays and Measurement Instruments. At the heart of the product line are the “Micro” series of SiPM sensors in a range of sizes and packages. Different series of SiPM sensors are targeted at different applications, but SensL SiPM sensors share in a number of common characteristics, of low noise, high breakdown voltage uniformity, low temperature coefficient and low bias voltage. SensL was formed in 2004 and has been driving the development of SiPM technology ever since. Their SiPM technology offers industry-leading uniformity in operating voltage and optical response, enabling world class system performance and compelling cost advantage. SensL has over 500 customers who have implemented its low-light sensors in a wide range of applications including medical imaging, biophotonics, hazard and threat detection and LIDAR. SensL strive to help all customers learn and implement their technology by having a focus on application technical support and an engineering commitment to maintaining leading edge sensor and packaging developments. SensL was acquired by ON Semiconductor on 9th of May 2018.

Engagement with CAPPA

PIN photodiode and APD’s have traditionally been used as light sensors in LIDAR applications but maximum range is limited in these systems due to the sensitivity of these devices. SensL SiPMs off single photon detection capability which allows maximum range to be extended for an equivalent laser power. SensL has developed a linear SiPM array based scanning LIDAR demonstration platform, intended to show how SiPM technology can be applied in this area. The intention is to deliver the SiPM sensors to OEMs for application in the automotive industry for collision avoidance systems and self-driving cars. This reference design serves as a guide for customers to start to evaluate the technology. Testing the demonstrator involved imaging and gathering statistical data on calibrated targets at distances from up to 150 meters from the sensor and suitable test sites needed to be identified.

How CAPPA Delivered Solution for Industry:

The CAPPA centre provided the use of the running track facility to perform outdoor tests in bright sunlight conditions. The test results were compared and used to validate a model of the system. Once the model has been validated it can then be used to model different scenarios for customers in order to  provide optimal SiPM design solutions for their partners.

“Many thanks to the team at CAPPA, once again for supporting us in our testing and for their technical advice. They were always flexible and helped rearrange dates when the weather was inclement.”
