In this paper, a direct design method for an off-axis two-mirror telecentric scanning system with a linear field of view (FOV) is proposed. A single freeform mirror structure is firstly considered, in which the aberration free geometry of the off-axi

We present a compact dual-view endoscope imaging system with a field of view (FOV) of ±80° and F/# of 3.4. The endoscope consists of two optical configurations for increasing FOV within the volume constraint. The front view configuration is a fishe

We substitute a freeform surface consisting of the off-axis parabolic (OAP) surfaces for the collimating mirror and each sub-region of the focusing mirror, to achieve an aberration free spectrometer.

The classic Czerny-Turner spectrometer consists of a plane grating and two spherical mirrors. The optical path geometry adopted for incident and grating dispersed light is off-axis reflection, so the spherical collimating and focusing mirrors introdu
