The eyepiece is engraved “ZEISS West Germany 46 40 03” and is commonly described in discussions of Zeiss optics as W10X\/25, a wide-field design historically associated with König-style field-stop construction. Some marketplace listings identify the same model as W10X\/25 with a 30 mm field diameter, reflecting catalog measurement variations from the era. Used in general microscopy and educational settings, it supports broad-field viewing with edge-to-edge illumination typical of Zeiss wide-field oculars.\u003c\/p\u003e\u003c\/div\u003e","brand":"Carl","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677677191470,"sku":null,"price":297.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_6436f609-59ad-4e21-8d06-75ef6472e324.jpg?v=1769566345","url":"https:\/\/plgautomation.com\/products\/carl-zeiss-46-40-03-w10x-25-microscope-eyepiece","provider":"PLG Automation ","version":"1.0","type":"link"}
