Unknown device / Physics equipment. Please identifiy....

Click For Summary

Discussion Overview

The discussion revolves around identifying an unknown piece of physics equipment, with participants exploring its features and potential uses. The scope includes equipment identification and possible applications in physics and medicine.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant describes the device as having a focusable optical target with three green lines and white "pens" that dip in ink and mark something.
  • Another participant provides a link to a surplus store, possibly suggesting a source for similar items.
  • A later reply suggests that the device might be a "polarimeter" based on further research.
  • One participant challenges the polarimeter identification, noting that it does not account for the function of the white pens.
  • Ultimately, a participant concludes that the device is a lensometer used in optometry, indicating a shift from a physics-related context to a medical one.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the initial identification of the device, with multiple competing views regarding its purpose and function throughout the discussion.

Contextual Notes

There are limitations in the discussion, including assumptions about the device's function based on its features, and the lack of clarity on how the white pens operate in relation to the identified uses.

Eecinee
I'm stumped by this one... Any idea what it is? Inside there is a focusable optical target with 3 green lines. The white "pens" dip in ink and mark something. Any ideas?

This does not appear to be any sort of standard polarimeter. This does not explain the white pens that mark on some surface.
 
Figured it out.. thought it was physics / science related but actually it's medical. It's a lensometer for optometry.
