Confocal Interferometer CFP-1

The confocal Interferometer CFP-1 is a very high resolution spectrometer. The 500mm confocal cavity gives a resolution approaching 5MHz. Optics are included to allow an optic fibre to be optimally coupled to the cavity. A very narrow bandpass interference filter rejects stray light, and a glass plate beam splitter couples out a small amount of the incoming light for reference purposes.

The cavity has been factory-preadjusted to achieve optimum performance and requires no subsequent adjustment – however alignment screws are provided for the unlikely event that further adjustment is needed.

Highly sensitive piezoelectric scanning is employed, requiring about 1.5V per order at a wave-length of 532nm.
