Detailed Description

A simple plug-in to add emission lines from standard gas lamps to the current spectra.

The lines displayed are limited to those appearing within the current spectrometer's configured wavelength calibration. Lines are scaled to the current spectrum, and relative intensities are roughly set to approximate typical appearance.

Member Function Documentation

generate_points()

EmissionLines.EmissionLines.generate_points	(		self,
			lamp )

Generate a synthetic spectrum, bounded in x to match the specified x-axis in wavelengths, bounded in y to match the min/max of the specified spectrum, of the specified lamp's emission lines.

get_configuration()

EmissionLines.EmissionLines.get_configuration

(

self

)

End backwards compatible object-returning wrappers #####.

Can be called BEFORE or AFTER connect. Should be idempotent. Ideally should return same object on multiple calls, but at least should be "equivalent" objects.

Returns

an EnlightenPluginConfiguration

Reimplemented from EnlightenPlugin.EnlightenPluginBase.

get_lamps()

EmissionLines.EmissionLines.get_lamps

(

self

)

Emission lines with relative intensities of 0 appear in literature, but are either unverified or hard to see with our spectrometers in empirical usage.

Relative intensity will realistically vary by model, but these values are a reasonable starting point.

Todo

for completeness add He, Rn

Sources

Data taken from NIST, as well as calibration lamp vendor websites.

Returns

dict of emission lamp sources (Argon etc), each containing a dict of wavelength with relative intensity (relative to other lines of the same element)

process_request()

EmissionLines.EmissionLines.process_request	(		self,
			request )

Reimplemented from EnlightenPlugin.EnlightenPluginBase.
