Concept:
The stereomicroscope (also known as a dissecting microscope) is designed to provide a three-dimensional (3D) view of specimens.
Step 1: Understanding stereomicroscope.
A stereomicroscope uses two separate optical paths with two objectives and eyepieces to produce a 3D image.
Step 2: Historical contribution.
Cherubin d’Orleans, a Capuchin friar in the 17th century, is credited with developing the early form of stereoscopic microscopy.
Step 3: Evaluating other options.
• Robert Hooke → known for compound microscope improvements
• Calvin Goddard → forensic ballistics expert
• Alexander (incorrect attribution)
Step 4: Final evaluation.
Thus, the correct inventor is Cherubin d’Orleans.
Final Conclusion:
Hence, the correct answer is option (4).
