Achromatic doublet design

We need an achromatic doublet lens designed for us. The lens needs to be an achromatic doublet lens with a focal length of 40mm and a diameter of 50mm. We would need the project to identify off the shelf lenses to buy for us to assemble together. We would ideally buy the lenses from either Edmund optics or thorlabs so please select lenses from either of these two companies. If these companies do not have the suitable lenses, then we can order from elsewhere and even look into ordering a custom lens. Vis AR coatings are essential. We look forward to hearing from you soon. Thanks in advance.
