Basic properties of the SPHERE IFS.

Parameter	SPHERE-IFS
Detector	2048 × 2048 H2RG
No. of lenslets	≈152 × 152
Lenslet lattice configuration	hexagonal
Lenslet area	370 mas^{2 (a)}
Field of view	1″.73 × 1″.73
Wavelength coverage	0.95−1.66 µm
Microspectrum length	~39 pixel^(b)
Separation between spectra	~5 pixel^(b)
R = λ/δλ	~55; ~35 ^(b)

Notes. ^(a) Area of hexagonal lenslet on sky. Resampled by the pipeline to ~(7.4 mas)² per square pixel. The side length t of the hexagon is 7.4 mas, and the area . ^(b)Microspectrum length, spacing, and R may vary slightly depending on definitions and may vary slightly across the FoV.
