Meaning and Definition
A specialised optical instrument used in crystallography and petrography for observing and analysing the interference patterns (conoscopic figures) of a crystal, typically under convergent polarized light.
In a broader optical context, any device or arrangement used to observe the far-field pattern (angular distribution) of light emanating from a source or passing through an optical system. However, this extended use is rare and highly technical.

British vs American Usage
Differences
No significant differences in meaning or usage. Both varieties use the term exclusively in its technical sense.
Connotations
None beyond its strict technical definition.
Frequency
Equally rare in both varieties, confined to identical technical fields.

FAQ
Frequently Asked Questions
Typically, no. It is most often a specific optical configuration or attachment (involving a Bertrand lens) on a polarizing microscope, not a separate device.
Primarily mineralogy, petrography, crystallography, and optical materials science for identifying minerals and analysing crystal symmetry.
No. The observation requires a prepared thin section of a crystal, placed under a polarizing microscope with specific settings to create and view the interference pattern.
Orthoscopic observation uses parallel light to view the crystal's features in a standard, magnified image. Conoscopic observation uses strongly convergent light to produce an interference pattern that represents the crystal's optical properties in all directions at once.
