Design
Compact. Robust. Light.
The xScape100 VNIR OFE is dimensionally and structurally optimised for 3U and 6U Cubesats while staying inline with the GSFC-STD-7000 environmental testing standards. The image plane is designed to accommodate an APS-C like sensor and maintain performance across a wide spectral and temperature range.

MTF VS FIELD HEIGHT
Consistency across the field.
The xScape100 OFE is designed for consistent performance across the field height in all spatial frequencies.
MTF across the field @ 93 lp/mm
TRANSMISSION
Optimal transmission across the spectrum.
The transmission, with obscuration, is maintained across the field for the visible and near-infrared spectral range.

DISTORTION VS FIELD HEIGHT
Accurate pixel mapping across the field.
Distortions are limited to a fraction of a pixel in each wavelength across the object field, making the xScape100 OFE ideal for TDI based sensors.
