Zeiss Ultra-Optimeter:
- The Zeiss Ultra-Optimeter is a precision optical measuring instrument used for comparative measurements of small components, such as gauges, threads, and other machined parts. It operates on the principle of optical magnification and projection, allowing users to compare the shadow or profile of a workpiece against a master template or scale on a screen.
Role of Mirrors in the Ultra-Optimeter
- The instrument uses two mirrors to achieve magnification and accurate projection:
First Mirror (Objective Mirror):
- Positioned near the workpiece.
- Captures the shadow or profile of the object and reflects it toward the second mirror.
- Helps in the initial magnification and alignment of the optical path.
Second Mirror (Projection Mirror):
- Receives the reflected image from the first mirror.
- Further magnifies the image and projects it onto a viewing screen.
- Ensures a sharp, distortion-free image for precise measurement.
Why Two Mirrors:
- Optical Path वलयन: Two mirrors allow the light path to be "folded" within a compact instrument, making it more ergonomic and space-efficient.
- Magnification Control: The combination of two mirrors helps achieve the desired magnification (often 10x, 20x, 50x, or higher) without excessive distortion.
- Image Clarity: A single mirror would not provide sufficient magnification or correction for aberrations, while more than two mirrors would complicate the system unnecessarily.
