Descriere
- Field of views are calculated at 0 dpt power of the liquid lens.
- Working distance (nominal): distance between the front end of the mechanics and the object at 0 pdt power of the liquid lens.
- Minimum and maximum working distance are reported at nominal range of the liquid lens; maximum excursion may be larger.
- Considering repeatability on the optical power of the liquid lenses over small (±0.05 dpt) and big (±0.1 dpt) steps
- Working f-number (wf/N): the real f-number of a lens in operating conditions.
- Maximum angle between chief rays and optical axis on the object side, evaluated at 0 dpt power of the liquid lens. Typical (average production) values and maximum (guaranteed) values are listed.
- Maximum values calculated in the range -2 to +3 dpt of the liquid lens.
- Percent deviation of the real image compared to an ideal, undistorted image, , evaluated at 0 dpt power of the liquid lens. Typical (average production) values and maximum (guaranteed) values are listed.
- At the limits of the depth of field, the image can still be used for measurements. For a very sharp image, however, only half of the depth of field should be considered. Pixel size used for calculation is 3.45 μm.
- Object side, calculated with the Rayleigh criterion with λ= 520 nm
- Typical at 30°C, 0 to ±250 mA step.
- Indicates the availability of an integrated camera phase adjustment feature.
- Measured from the front end of the mechanics to the camera flange.
