This category is for listing COMPANIES, so please submit company sites, not product sites. The title of your site should reflect your company name, nothing more. Note that this is for companies who sell or resell high technology, high precision, optical equipment, such as precision lenses, mirrors, detection or imaging equipment, and prisms. Laser entertainment (such as light shows) does not belong in this category. It belongs in a business or entertainment category. Companies selling low-tech products which can be purchased at a local general store probably is not appropriate for this category. This would include small He-Ne lasers for use as laser pointers, 3-D glasses, and light bulbs. A business category would be best in that case.
