I'm looking to place an order for a specific type of lens. The required specifications include a diameter of 15mm with a focal length of -50. Additionally, the lens should have an anti-reflective coating suitable for the wavelengths of 532 and 1064 nm. For dimensions, the lens should be 3mm thick, with an edge measurement of 1.8mm at the center. I would like to request a total of 5 pieces. Please provide me with the pricing and availability for this order at your earliest convenience. Thank you!
