Talk:Refractive index and extinction coefficient of thin film materials

Is this article self-promotion?
I have some concerns about whether this article should be considered self-promotion. This article is not really about the refractive index and extinction coefficient of thin film materials. That is an extremely general topic and there are several alternative methods. This article seems to be about a specific methodology for determining the refractive index and extinction coefficient using the Forouhi–Bloomer model. The article was created by Nandktech, but n&k Technology is a company and the executive team consists of Dr. Forouhi and Dr. Bloomer. Additionally, the examples in the article contain no references but look very similar to those on the company's website advertising their capabilities.

There is another article on the Forouhi–Bloomer model. Full disclosure, I made it along with several other refractive index model pages. I just cannot get over the fact that this article seems like it could be deleted.

 * I'm inclined to agree with you. The article was clearly written by N and K Tech to promote their products/methods.  While the content is not useless, it certainly does not make good on its promise to cover the topic described in the title in a general or broad sense.  Instead, it covers one narrow area within the topic, and even then, only describes one method. Tarheels 100 (talk) 16:57, 9 February 2023 (UTC)
 * I agree with the comments from Engiqueer and Tarheels 100. I will mark this as having Notability and Neutral point of view with a possible Criteria for speedy deletion. Let's see is anyone responds. Ldm1954 (talk) 21:54, 24 August 2023 (UTC)
