The ASP-IR-3.5 from Avesta Ltd. is a Scanning IR Spectrometer that operates at a spectral range of 1200 nm - 3450 nm. It has a spectral resolution of 1.2 nm (free-space) and 1.5 nm (given for 400 μm fiber core). This Czerny-Turner spectrometer has a grating with 400 grooves/mm and a scanning speed of up to 400 nm/s. It has a relative dynamic range of 6[1.5] x104 and a focal length of 150 mm. This spectrometer has a 15 μm input slit and a 20 μm output slit with a relative aperture of 1:13. It has a 16-bit, 65536 counts ADC and can be controlled via a USB-connected PC interface.
The ASP-IR-3.5 has free space and SMA905 fiber socket input (FC socket or fiber patch cord are available on request). This spectrometer has an InAs PV-cooled photodetector with a detector active area height of 1mm. It has a Noise Equivalent Power (NEP) of 145 nW and Noise Equivalent Energy (NEE) of 7 pJ. This spectrometer is available in a package that measures 295 (L) x 136 (W) x 81 (H) mm and is ideal for biological imaging, laser systems design, integration and amplification, ultrafast laser diagnostics, laser wavelength control, spectral analysis of various light sources, NIR and MIR spectral analysis, and laser emission analysis applications.
