🥚 Finding signal in the noise - an Easter analogy worth remembering, from an Application Specialist @ Oxford Instruments Andor
Sensitivity in spectroscopy is determined by a combination of the noise floor and the quantum efficiency.
Imagine an Easter egg hunt where the egg represents the signal, and the grass represents the noise floor.
When the grass is unkempt and overgrown, the egg is difficult to find, when the grass is well-manicured and short, the egg is easy to spot, even from a mile away.
☘️ Your spectrograph plays a bigger role in that "grass" than you might think.
The primary goal of any research lab is to obtain accurate, reliable results as efficiently as possible. However, valuable time is often lost using ineffective spectrograph systems that are difficult to operate.
📉 Some of the main pain points we often hear, and how Oxford Instruments Andor solves them are in the photos.
Did you catch the eggcellent pun?
