Lenses

Many different objective lenses are available for each imager. The objective lens determines the imager's field-of-view (FOV) as described below.

Line Scan Imaging
Resonon hyperspectral cameras are line-scan imagers that build a 2D image one row at a time. Each camera frame captures a single row of pixels, and a complete 2D image is composed of many frames (typically 500 - 2000 per image).

Field of View (FOV)
The Field of View defines the long dimension of the line “seen” by the imaging spectrometer in units of degrees. (See below.) The user can change the FOV by changing objective lens. See the table below to identify the lens that provides the optimal FOV for your application.

Description: fov & ifov.bmp

Instantaneous Field of View (IFOV)
The Instantaneous Field of View defines the narrow dimension of the line “seen” by the imaging spectrometer. The IFOV is traditionally reported in units of milli-radians.
