Lasers

• 785nm (power range between 18 to 176mW on a sample)
• 660nm (power range between 1 to 32mW on a sample)
  Spectral range
• 400-2700cm-1 (from 785nm laser),
• 2750-4500cm-1 (from 660nm laser)
  Spectral resolution
• 7-15cm-1 (slit size dependent; slit size can be customised)
  Sensitivity in point mode from laser wavelength 785nm (determined as SNR of polystyrene spectrum). SNR should be in the range 250:1 to 350:1 from 785nm laser (spectral range 400-2700cm-1) at the following parameters:
• laser wavelength: 785nm
• laser power: 100mW
• integration time: 0.1s
• number of repetitions: 1
• objective: dry microlens
• smoothing : non
