This year marks Adimec’s 25th anniversary—a milestone that reflects two and a half decades of innovation in camera technology. Over these years, we’ve accumulated substantial knowledge about imaging systems, from design principles to manufacturing processes.

As part of our Throwback Thursday blog series exploring the evolution of camera production at Adimec, today’s focus is on an early sensor alignment and linearity measurement tool. This system exemplifies the engineering challenges overcome in earlier generations of cameras like the TMX5 CCD model.

Sensor Alignment Process

Achieving precise lens-sensor alignment was critical for minimizing optical distortions. The process involved projecting a crosshair pattern onto the camera image using either an optical lens or digital display technology. By carefully adjusting mechanical components, engineers could match these patterns to ensure accurate registration between the lens mount and sensor array.

The system incorporated a manual adjustment mechanism that allowed technicians to achieve subpixel accuracy—initially measuring within 5 pixels (approximately 40-85 microns). While modern systems have automated much of this process with precision robotics, the fundamental principles remain relevant today.

Linearity Measurement

Linearity testing verified how consistently camera sensors responded across different light levels. By systematically varying illumination intensity using neutral density filters projected onto test patterns, engineers could establish a relationship between input photons and output electrons—a critical parameter for scientific imaging applications where quantitative accuracy matters most.

This historical perspective reveals both the remarkable progress in camera manufacturing technology and enduring engineering principles that continue to shape modern imaging systems at Adimec.
