Theta lens
WebRelative Illumination. Relative Illumination (RI) is a way to represent the combined effects of vignetting and roll-off in an imaging lens and is given as a percentage of illumination at any point on the sensor, normalized to the field position with maximum illumination. An RI curve quantifies changes in illumination (%) across the sensor. WebThe LINOS ® F-Theta-Ronar lenses are designed to achieve aberration-free imaging for laser wavelengths between 940 – 980 nm, allowing exceptionally small spot diameters over the …
