If you want to calculate the sourcepower from a specific source, you need to use sourcepower(f, option, name), where &ldquo;name&rdquo; is the name of this source.&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;If you have two sources each corresponding to a different single wavelength, most of the power for this wavelength will come from the corresponding source. For example, let&rsquo;s assume that you have two sources named source_400 which has wavelength of 400nm and source_700 which has wavelength of 700nm. If you look at the sourcepower that corresponds to 400nm using script, you will get the following results:&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;&lt;span style=&#8221;mso-no-proof: yes;&#8221;&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/12\/16-12-2024-1734341233-mceclip0.png\" \/>&lt;br&gt;&lt;!&#8211;[endif]&#8211;&gt;&lt;\/span&gt;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;The sourcepwer of source_700 that corresponds to 400nm wavelength is 11 orders of magnitude lower than the one of source_400. Hence, if you use sourcepower(f_400) without specifying the source name, you will get the sourcepower of source_400 since the sourcepower of source_700 at 400nm wavelength is negligible.&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;Best regards,&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;Afroditi&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-397586","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Dear Pengsheng, Thank you for contacting us.
