Notes
- Working distance: distance between the front end of the mechanics and the object, reported at nominal range of the liquid lenses; maximum excursion may be larger.
- 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.
- Percent deviation of the real image compared to an ideal, undistorted image.
- At the borders of the field depth the image can be still used for measurement but, to get a perfectly sharp image, only half of the nominal field depth 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.
- For controller data, see Optotune website
- Indicates the availability of an integrated camera phase adjustment feature.
- Measured from the front end of the mechanics to the camera flange.
