Features
▶ Aberration Corrected Spectrograph
-
Aberration corrected design based asymmetric Czemy-Turner with diffraction optics
-
Excellently aberration corrected over the whole pixels on CCD array
-
RMS spot radius on the CCD < 10㎛
-
-
Excellently improved throughput and resolution compared to traditional Czerny-Turner spectrograph
-
Best performance for low light application such as Raman spectroscopy

▶ Motorized Slit
-
Precision entrance motorized slit
-
The slit width can be adjusted between 10 to 1000㎛ with 10㎛ step resolution
▶ Fast Mapping
-
Fast mapping function is able to offer many advantages to the user
-
It is possible to use readout times as short as around 10㎳ per spectrum
-
Depending on CCD model line; lower is possible too
-
▶ Wide Range Mapping
-
There are no limits to mapping area imposed by the objective FOV
-
From micro area to macro area with micro spatial resolution
-
Max range : 75㎜ x 50㎜
