ASP-IR小型高精度光譜儀

特點：

紅外光譜測量值可達3.5μm

緊湊

分辨率0.5nm

USB接口

自由空間和光纖耦合FC輸入

產品概述：

ASP-IR有掃描裝置，可以測量紅外波長范圍，不使用昂貴的CCD陣列。這在紅外光譜儀市場上，非常有價格優勢。ASP-IR性能優異，能夠在整個波長范圍內，提供準確的激光輻射分析，分辨率0.35nm。

ASP-IRF專用光纖輸入，可以測量8個自由空間或光纖信號，無需重新對準。

可訂購波長范圍達3800nm。

(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.
