Answer #1

Answer)

What is a photodiode array detector- Diode arrays having a number of element ranging from 128-1024and even up 4096 are also available

Advantages of photodiode arrays detector over a single photodiode detector.

1) simultaneous multiwavelength measurement but a single photodiode detector can only measure a single wavelength.

2) Fast scan speed while a single photodiode detector scan speed is slow.

3) High signal to noise ratio

a single photodiode detector requires 1s for 1 data point

photodiode arrays detector requires 1/1000 sec for 1 data point

4) Wavelength precision

5) Minimal stray light effects
