(1) – each spectrometer is equipped with a fiber socket and allows measurement of either free-space or fiber signals without any realignment
(2) – all spectrometers have two operational modes: CW (repetition rate from CW down to 6 kHz) and pulsed (up to 8 kHz for ASP-IR-1.7 and up to 25 kHz for ASP-IR-2.6 and ASP-IR-3.5); the pulsed mode has external trigger feature
(3) – dynamic range for pulsed mode given in brackets
(4) – NEP - noise equivalent power and NEE - noise equivalent energy are given at input beam diameter ~ 2 mm at peak sensitivity wavelength (ASP-IR-1.7 – 1.5 um, ASP-IR-2.6 – 2.3 um, ASP-IR-3.5 – 3.25 um)
* - typical values.
