The ST2000 utilizes high resolution zoom optics combined with a state-of-the-art video capture device to provide real-time, crisp, detailed images. Our 12:1 programmable zoom system allows the user to automatically, or manually zoom to the desired magnification for a specific inspection or measurement task. The zoom is calibrated throughout its entire range so, highly accurate field-of-view measurements can be taken at any point in the zoom range.  Sertek also offers several manual zoom modules including 7:1, 12.5:1, 16:1 and a 10:1 Telecentric Zoom. So, no matter what you magnification requirements are, the ST2000 offers the solution.

Z-axis measurements are performed using the "focus method". By focusing on two surfaces, the system can report the height between the two. Utilizing a 0.1 micron linear encoder on the Z-axis and a 1.6 micron depth of field infinity corrected objective, the ST2000 is able to measure heights and depths with an accuracy of +/-2.5 microns. This will vary depending on your accuracy requirements as well as your magnification specifications. Programmable, stepper motor control makes the whole process automatic.
