Optical Spectrum Analyzers

  1. Jul 29, 2008 #1

    My department is considering to purchase an Optical Spectrum Analyzer (OSA). I had run a search on GlobalSpec, but I am really getting confused over the hundreds of spectrum analyzers available. I am looking for a diffraction-grating based analyzer that covers a broad range of wavelengths. Does anyone here has experience in this field and make some suggestions on the suitable parameters I should be looking for in an OSA?

    Thanks in advance,

    What range of wavelengths do you want? Other important features would be resolution and computer interface + software.

    Here are 2 models:

    Also, it's very useful to have 1 or 2 calibration lamps to calibrate the wavelength scale:

    Hi Redbelly98!

    Thanks for replying. The links you gave me were spectrometers. What I am a looking for is a spectrum analyzer. Spectrum analyzers have a much higher resolution. I am looking for one in the short-wavelength limit. But so far I have found only those in the higher wavelength range.

    Here is a search on photonics.com that might be of help. Like you say, there are lots of choices.
