Column "To": S = list of suppliers for that product, E = encyclopedia article.

Third column: alternative suppliers are suppliers also offering such products while having an ad package. On their own company profile pages, the right column of the table contains their product descriptions instead of alternative suppliers.

Trouble with Specifications

Specifications for lasers and other photonics products are essential for the process of buying such things. Nevertheless, many do not properly deal with them:

Many product specifications by suppliers lack quality – they are incomplete, not sufficiently clear, etc.
Buyers are often not aware of what they really need. For example, they forget essential requirements.

Various problems can arise:

Due to a lack of clarity, tedious communications between supplier and buyer are required.
Product specifications raise expectations which cannot be met.
Conflicts can arise over such issues.

Our Photonics Spotlight article and our encyclopedia article on laser specifications give you important hints. In case of doubt, contact RP Photonics to get competent and impartial advice.
