The new AvaSpec-2048L Fiber Optic Spectrometer is similar to the standard AvaSpec-2048 with the only difference being the CCD detector integrated in optical bench. The AvaSpec-2048L uses the Sony ILX511B detector whereas the AvaSpec-2048 uses the ILX554B detector. The AvaSpec-2048L is very useful for applications where a larger fiber entrance diameter is needed for projection onto the CCD detector pixels which are 14x200µm height on the ILXB11B (compared with 14x56µm for the ILX 554B). The AvaSpec-2048L has superior signal to noise performance and shows no peak inversion or dark increase at the end of the detector array at longer integration times. The FWHM resolution of the 2048L is ca 20% less than the standard 2048 and also non-linearity is somewhat lower, so an NL-calibration is recommended. All options for the AvaSpec-2048 are also available on the AvaSpec-2048L.
