A stereoscopic microscope is an optical microscope that provides a 3D-view of a specimen. It uses two separate optical paths with two objectives and two eyepieces to provide different viewing angles to the left and right eye (for DIC, we use instead two C-mount cameras) – in this way it produces a 3D visualization of the sample being examined.
A 2-camera FlexDIC or a 2-camera ThermechDIC system (with up to 12 Mpx resolution) can be retrofitted with a stereoscopic microscope (DSM 61030: Stereoscopic Microscope) (µDIC) for 3D-shape, displacement, and strain information for object sizes from 100×100 µm up to 15×15 mm i.e. Field-of-View (FoV) from 2.5 mm to 36 mm. Cameras, cables, Laptop PC, and the DAQ controller can all be interchanged/swapped between a conventional FlexDIC / ThermechDIC system and a stereoscopic microscope.
The stereoscopic microscope (DSM 61030: Stereoscopic Microscope) consists of a C-mount video extension tube adapter for two machine vision cameras (up to 12 Mpx). Objects under measurement are magnified by a planachromatic or planapochromatic lens and illuminated by a photo-red ring-light source. The complete unit is mounted on a light base with anti-shock feet. With the gliding stage the samples can be exactly positioned. All together making µ-measurements highly accurate.
