Inquiry about Precision Pinholes NEW

I am looking for two precision pinholes for a laser spatial filter: one 5 µm and one 10 µm. Both should be mounted in 1" (25.4 mm) black-anodized aluminum housing and clearly labeled with the aperture size. They will be used with a 405 nm laser and a 20× / NA 0.40 microscope objective for spatial filtering. Please provide the following details: - Aperture tolerance for 5 µm and 10 µm - Centering tolerance in the 1" mount - Recommended pinhole material and thickness - Price for 1 piece of each size - Shipping cost to Germany - Production and delivery time If you offer both standard stainless-steel and high-power copper versions, please advise which one is more suitable for this application.
