Ultra-Highspeed camera manufacturer Vision Research just released two new models: the Phantom TMX5010 and T3610. Capable of capturing motion at up to 1.16 million fps, these cameras feature a CMOS Backside illuminated Sensor for maximum sensitivity. Ultra-highspeed cameras are an extension of our eyes. They allow us to observe events that would be impossible to see otherwise. However, shooting at extremely high frame rates comes at a price. Since each frame is only exposed to light for infinitely small fractions of a second, these cameras are light-hungry beasts. As a consequence, the sensors in cameras like these require very high sensitivity. To address this problem, the new Phantom TMX5010 and T3610 feature a Backside Illuminated (BSI) sensor, a technology that greatly improves low light performances. Let’s go through the basics of how it works. The Phantom TMX5010 and T3610 feature a Backside Illuminated sensor.

Many traditional camera manufacturers have been relying on this technology for years, but up to this day, it has been technically difficult to implement into ultrahigh-speed cameras. With the Phantom TMX5010 and T3610, Vision Research is pushing the boundaries of what’s possible. It is commonly thought that a camera’s sensitivity depends on its ISO. However, this belief is wrong. Instead, the sensitivity of a digital sensor depends on its Quantum Efficiency (QE). In a nutshell, Quantum Efficiency measures how capable a sensor is in converting particles of light (photons) into particles...
