Available Plano Substrates
OPTOMAN has a number of 1/2″, 1″, 2″ and 3” plano substrates in stock, ready to be coated. Choosing the in-stock substrate option allows, on average, saving 6 weeks of lead time and reducing end-product cost 3 times.
Choose the suitable plano substrates and OPTOMAN will make custom coatings on them. OPTOMAN is a coatings superhero, so uncoated substrates are not for sale.
