{"id":256,"count":0,"description":"Apochomatic Doublet\r\n\r\nIs a lens with 2 types of glass processed against each other, where 1 type of glass has a low color error. Actually, an apochromat is a lens with 3 types of glass facing each other.\r\n\r\nBut due to current coating techniques, doublet lenses are also called apochromate. This is because they have the same optical values.\r\n\r\nManufacturers can thus deliver a good optical telescope cheaper to the customer.","link":"https:\/\/dev4-ganymedes.nl\/en\/product-category\/telescopes-en\/telescopes-refractor-telescopes-en\/telescopes-refractor-apochromatic-doublet-en\/","name":"Apochromatic doublet","slug":"telescopes-refractor-apochromatic-doublet-en","taxonomy":"product_cat","parent":251,"meta":[],"menu_order":55,"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Apochromatic doublet - Ganymedes<\/title>\n<meta name=\"description\" content=\"Apochromatic Doublet, is a lens with 2 glass types on top of each other where 1 glass type produces a very low color error.
