Resolution

0.25 cm-1,0.5 cm-1, 1 cm-1, 2 cm-1, 4 cm-1, 8 cm-1, 16 cm-1 (Middle/Far IR)
2 cm-1, 4 cm-1, 8 cm-1, 16 cm-1 (Near IR)

S/N ratio

60,000:1 or higher(Standard; 4cm-1 resolution, 1 min. scan, around 2,200cm-1, peak-to-peak)

6,000:1 or higher(Microscope; Transmittance mode, aperture 50¡Ñ50μm, 8cm-1 resolution, 120 scans)

8,000:1 or higher(MCT measurement; 4cm-1 resolution, mirror speed 9mm/s, 120 scans, MCT detector)

2,000:1 or higher(Rapid scan; 16cm-1 resolution, mirror speed 40mm/s, 1 scan, MCT detector)

10,000:1 or higher(NIR measurement; 4cm-1 resolution, mirror speed 2.8mm/s, 34 scan, InGaAs detector)

* SN ratio with a DLATGS detector is 48,000:1 or higher when a MCT kit or an NIR kit is mounted.

* When a sample compartment window is changed to a KRS-5, the SN ratio is 75% of that attained with a KBr window.
