ASP-150T zoom in

   The ASP-150C spectrometer is an ideal choice for a wide variety of different optical applications with its flexible tuning and high resolution.
   The ASP-150T model is able to carry out measurements in a wider spectral range without any losses in resolution, owing to a special rotating mechanism.
   There is always a place for the ASP-150C on the optical table due to its small size, functionality and friendly interface.
    Models ASP-150CF and ASP-150TF have the special fiber input with a spectral slit, the size of which is conditioned with the detector. It allows measurement of either free-space or fiber signals without any realignment. However, it is not recommended to use fiber to measure spectrum of a femtosecond laser due to signal modulation and subsequent spectrum distortion.

	(1) - the necessary width and center of the registered range should be specified when placing an order. The ASP-150T has an operational range adjustment function. (2) - for models ASP-150CF and ASP-150TF. (3) - any array can be combined with any grating type. (4) - sensitivity given at the wavelength of 550 nm. (5) - the Hamamatsu arrays provide for sensitivity control via special driving signal, that can set either low (values in brackets) or high sensitivity mode. (6) - the property of the CCD to prevent the charge flow from the neighboring overexposed pixels.
