Design & Engineering

QSI is staffed by an exceptional engineering team, each with more than 20 years of industry experience in electrical, mechanical and software engineering.  They’re backed up with state-of-the-art tools including 3D CAD/CAM software, electronic design and testing software, and advanced software development tools.  Mechanical designs are developed in SolidWorks™.  Those 3D models are then fed directly into our CNC manufacturing systems to produce QSI’s elegant, compact and energy efficient products and do so with quality and cost that rivals the best in the world.

We use the products we sell so we better get them right.  There’s nothing better to focus the talents of an engineer or product designer than building a product they want to use. Reviewers of QSI cameras agree. Most have gone on to purchase a QSI camera for their own use.


Of course building great products requires much more than technical expertise.  Truly great products require forward-thinking, innovative designs and industry-leading performance.  QSI is a leader in the design and production of deep cooled CCD cameras for low light applications.  QSI cameras are relied upon by world-class organizations around the world:
