Linda,
Welcome. To gain respect on this forum (and to increase your sales) you need to contribute useful information. Provide a current price list as well as shipping policy and cost. The bulk of the purchases made by participants to this forum will be for components used for 3 color (640nm, 532nm and 445nm) laser projectors. Do your research and identify those optics that will be most attractive. As a initial suggestion, consider:
1. Zero order, coated 12-25mm diameter wave plates
2. 10-20mm coated narrow and broad band PBS cubes
3. High efficiency dichroic laser beam combiners, square and round 10-25mm in size
4. High reflectance dielectric mirrors 400-700nm with 1/2 wave or better surface accuracy, 10-25mm, square and round. This item would be valuable in 10 piece quantity at lower cost.
I currently deal with several Chinese national companies directly. Rapid response to e-mails, low quantity sales and VERY importantly, fast and LOW cost shipping will set you ahead of your competition.
