Until now, imaging of objects with differing heights and depths
was performed by taking multiple photographs while moving
the camera vertically (Z-axis motion). In contrast, TAGLENS allows
simultaneous probing of multiple heights or depths. Moreover, acaptured image is displayed in real time.

During normal focusing

When using TAGLENS

Multi Focus
Up to 20 cross-sectional images at arbitrary heights can be captured simultaneously
・A focused image in any specified Z-position can be captured

without mechanical drive system within the observation range
at an extended depth of focus.

Capturing various Z planes is now possible without moving parts

・Multiple images focused in given Z-positions can be captured.

TAGLENS-3D/Z-Adjust

Focus Stacking

3D shapes can be captured without mechanical action in the height direction

All-focused images generated from multiple cross-sectional images

・Select Z-Adjust with dedicated chart or Nominal Z-Adjust with theoretical values.

・Contrast peak position is extracted and synthesized from images captured while changing focal position (image stack).

・Using the height information obtained from Z-Adjust/Nominal Z-Adjust for TAGLENS-3D, point cloud data can be generated.

・After obtaining the image stack, output to other companiesʼ focus stacking software is also possible.

*Z-Adjust can be used only in combination with VMU-T1.
*3D shape data display/analysis software is to be prepared by the customer.

*Image upload file type varies by company specifications

High-speed focusing without mechanical action

Up to 3 cross-sectional images can be mixed for display within one frame・Contrast peak position is determined from the images captured during the focal sweep.

・Multiple height observation with TAGLENS at camera maximum frame rates.

・After image acquisition, It takes only 10 ms to determine the focus position.

・Ideal for observation targets requiring different brightness, as multiple pulsed light sources can be exposed within one frame.
