I am trying to get a sample read out from a laser diode on an oscilloscope. I get a good pulse signal if I shine my keychain flashlight on the detector, but a very noisy signal from the diode itself. What could be causing the noise in this system?
The factory calibration of your UV-VIS-NIR Spectrometer only includes wavelength but not response (irradiance). I can measure raw data which is only usable for transmittance/reflectance measurements. How do I get irradiance measurements?
