|(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) - each spectrometer is equipped with a fiber socket and allows measurement of either free-space or fiber signals without any realignment;
(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;
* - values given for the Toshiba 1304DG CCD array.
The ASP-150C spectrometer is an ideal choice for a wide variety of different optical applications with its flexible tuning and high resolution. There is always a place for the ASP-150C on the optical table due to its small size, functionality and friendly interface.
The ASP-150T model is able to carry out measurements in a wider spectral range without any losses in resolution, owing to a special tunable mechanism.
All models have a 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.
Avesta’s facilities will be closed for the New Year break from 30 Dec 2017 till 08 Jan 2018. We will resume all operations on 09 Jan 2018. However, we hope to provide periodic e-mail correspondence during the holidays. We wish you a fruitful and prosperous Year 2018!
Avesta is participating in the “LASER World of PHOTONICS 2017” (Munich, Germany, 26-29 June 2017) trade show. Feel free to drop by our booth B2.151 to see the TeMa Yb laser system along with the AA-20 autocorrelator and GECON supercontinuum generator. The trade show participation is supported by the Russian Export Center and organized by Expocenter and Russian Laser Association.
