OAP Off-Axis Parabolic mirrors are part of the primary paraboloid. Off-axis means that the optical axes of the two are parallel but not coincidence. The focus axis passes through the center of the focus and the OAP mirror from off-axis parabolic mirror manufacturers, and the distance between these two points is called the reflected focal length (RFL). The Angle between the focusing axis and the optical axis is the off-axis Angle.
The OAP Off-Axis Parabolic mirror can focus collimated beams or collimated dispersing light sources without chromatic aberration, and its off-axis design can spatially separate the focus from the optical path. The reflective design eliminates the phase delay and absorption loss introduced by transmitted optics.
