Remarks	When using coaxial lighting, low magnification may produce vignetting.When using infinity objectives as Auxiliary Lens Module (adapter available), the PMAG, FOV and NA of the BS-1008 depends on the parameters of the objectives.

WD: Working Distance;

PMAG: Primary Magnification;

FOV: Field of View in the Object side;

NA: Numerical Aperture;

Note: Infinity corrected objectives limit system's usable zoom range due to uneven illumination. Max sensor format is 2/3".

The Working Distance of BS-1008 decreases with the increase of the magnification of the Auxiliary Lens, and its object NA or Zoom Range increases with the increase of the magnification of the Auxiliary Lens. Therefore, the Auxiliary Lens can be selected according to the Working Distance or Zoom Range (The real Zoom Range is also determined by the Auxiliary Lens).

The core of choosing TV Lens with different magnification is to match your own camera. From the table’s Zoom Range column, one can find with the increase of TV Lens’ magnification, the Zoom Range of the system increases in the same proportion, but it will not have a great effect on the optical resolution. In order to save money, it is recommended to choose a small size camera, such as 1/3" camera.

Of course, in order to improve the signal-to-noise ratio or imaging quality of the camera, one can also choose a large size camera. Large size often means large pixel size, while large pixel size often means large dynamic range and high signal-to-noise ratio.
