During market hours, delayed exchange price information displays (delayed per exchange rules.Indicates the availability of an integrated camera phase adjustment feature.Object side, calculated with the Rayleigh criterion with λ= 520 nm.Pixel size used for calculation is 3.45 μm. 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.Typical (average production) values and maximum (guaranteed) values are listed. Percent deviation of the real image compared to an ideal, undistorted image,, evaluated at 0 dpt power of the liquid lens.Maximum values calculated in the range -2 to +3 dpt of the liquid lens.Maximum angle between chief rays and optical axis on the object side, evaluated at 0 dpt power of the liquid lens.Working f-number (wf/N): the real f-number of a lens in operating conditions.Minimum and maximum working distance are reported at nominal range of the liquid lens maximum excursion may be larger.Working distance (nominal): distance between the front end of the mechanics and the object at 0 pdt power of the liquid lens.Field of views are calculated at 0 dpt power of the liquid lens.Feel free to contact our Sales Engineers to check the feasibility. Didn't find what you were looking for?ĭon’t worry! We can integrate liquid lenses with many other models including those with coaxial illumination. Communication follows an open simple serial protocol, which can be implemented in any programming language on Windows or Linux (C#, Labview and Python source code available). The driver comes as a compact USB-powered current source with free software and can be used as a stand-alone solution or integrated into OEM designs. The electronically controlled liquid lenses enable to precisely tune the optical power of telecentric lenses adjusting the focus: this adjustment can be extremely fast with response times in the order of few milliseconds. This makes them a perfect choice for many inspection and measurement applications spanning from electronic and semicon segments to the automotive one, from pharmaceutical to fasteners. Thanks to their optical design, TCEL lenses ensure excellent optical performances both in terms of telecentricity and especially distortion throughout the entire operating range. This is particularly important for small fields of view due to the proportionality of the DOF with the magnification. TCEL series by Opto Engineering® features a perfect combination of telecentric optics and liquid lenses technology allowing to significantly increase the depth of field (DOF).
