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). This is particularly important for small fields of view due to the proportionality of the DOF with the magnification.

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 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.

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. The driver comes as a compact USB-powered current source with free software and can be used as a standalone solution or integrated into OEM designs. 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).

Hinweise

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.
Working F-number: 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: typical (average production) values and maximum (guaranteed) values are listed.
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.
Indicates the availability of an integrated camera phase adjustment feature.
Measured from the front end of the mechanics to the camera flange.
Maximum side dimension; the lens has an asymmetric shape.

a Performances calculated with monochromatic light (LED emission); performance range in white light is smaller

b Performances guaranteed when used with vertical optical axis; when used with horizontal optical axis performances drops due to gravity induced aberration of the liquid lens
