| aberration |
Any optical defect and/or design error which causes any of the processed light to deviate from reaching the focal point, therefore reducing the quality of the image. Field of View: The maximum view angle of an optical instrument. The number, in degrees, supplied by the manufacturer is the Apparent Field of View. To find the Actual Field of View ( also known as the Actual Field of View ), divide the Apparent Field of View by the Magnification.
