xScape200 VIS Optical Front-End
The xScape200 VIS OFE is optimized from 450 nm to 670 nm with performance across the image plane. This OFE is ideal for a wide range of visible earth observation applications.
Datasheet
Design
Compact. Robust. Light.
The xScape200 VIS OFE is dimensionally and structurally optimised for 16U Cubesats or micro-satellites while staying inline with the GSFC-STD-7000 environmental testing standards. The image plane is designed to accommodate full-frame sensor and maintain performance across a wide spectral and temperature range.

MTF VS FIELD HEIGHT
Consistency across the field.
The xScape200 OFE is designed for consistent performance across the field height in all spatial frequencies.
MTF across the field @ 157 lp/mm
TRANSMISSION
Optimal transmission across the visible 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.
