Microprism properties: dimension, orientation and edgePolishQuality

[Alixbonard]

Should dimensions (description: Edge/face dimensions of the prism) be linked to mathematicalShapes ?
Should the type of orientation (description: Orientation of reflective face vs cortical layers) be a string or defined as Controlled terms? Same question for edgePolishQuality.

NB: List of microprism properties:

Field	Description	Required	Type
material	Add microprism optical material	Optional	linked -> chemicalMixture
dimensions	Edge/face dimensions of the prism	Yes	Linked ->
prismAngleDeg	Apex or right angle spec	Yes	QuantitativeValue
orientation	Orientation of reflective face vs cortical layers	Yes	string?
distanceFromSurface	Distance between prism face and pial surface (move to device implantion)	Optional	QuantitativeValue
tissueReliefCuts	Whether relief cuts were made (make better Description)	Optional	boolean
edgePolishQuality	Quality spec of polished edges	Optional	string or controled term

edgePolishQuality:

• unpolished

  cut edge only, not smoothed.
  

• standard

  edges ground smooth, acceptable for most in vivo use.
  

• opticalPolish

  high-quality polish, low scatter, edges suitable for imaging.
  

• superPolish

  extremely smooth surface (<50 nm roughness).
