Returns processed ellipsometry timeseries data. Data is organized by property name (for example, film thickness or refractive index), where each property has its own arrays of timestamps and values sharing a common time axis.
​
data_id
string
required
The data entry UUID for the ellipsometry measurement
​
return_null_if_missing
boolean
default:"false"
If true, returns null instead of an error when no timeseries data exists for this entry
​
last_n
integer
Return only the last N samples per property (useful for incremental fetching during live monitoring)
​
elapsed_seconds
number
Only return data points after this elapsed time (seconds). Useful for incremental fetching during live monitoring.
​
property_names
array
If set, only these property columns are returned. Omit to return all properties.
​
available_properties
boolean
default:"false"
If true, skip the data and return a metadata-only response listing the available properties

​
Response

​
properties
object
Mapping of property names to their timeseries data. Each key is a property name (e.g., thickness, refractive_index).
​
property_units
object
Convenience mapping of property name to its unit
​
available_property_names
array
All property names recorded for this data entry, regardless of any property_names filter applied to the response
​
series_max_time
number
Maximum relative_time_seconds value across all properties
