AvaSpec-2048L Fiber Optic Spectrometer with LARGE pixels
The new AvaSpec-2048L Fiber Optic Spectrometer has been recently added to the Avantes product line and has many technical specifications comparable to the standard AvaSpec-2048.
The difference is the CCD detector, the AvaSpec-2048L uses the Sony ILX511 detector whereas the AvaSpec-2048 uses the ILX554B detector.
The AvaSpec-2048L is very useful for applications where larger fiber entrance diameter needs to be projected on the larger CCD detector pixels of 200µm height.
The AvaSpec-2048L also has a better signal to noise performance and shows no peak inversion and dark increase at the end of the detector array at longer integration times. The FWHM resolution of the 2048L is ca. 20% less good than for the standard 2048.Non-linearity is also a little less, so a NL-calibration per channel is recommended.
All options for the AvaSpec-2048 are also available on the AvaSpec-2048L, the DCL-UV/VIS-200 has been added to optimize sensitivity for fiber diameters larger than 200µm.
