International Standard Microscope Objectives
商品货号:ECS001931
商品品牌:Edmund
详细介绍

Our full selection of microscope objectives can be used with all major brands of microscopes. Our matrix includes both DIN (Deutsches Institut für Normung) 45mm standard and JIS (Japan Industrial Standards) 36mm standard objectives. All optics are AR coated. DIN microscopes are configured for a 160mm tube length, and JIS microscopes for a 170mm tube length. DIN and JIS objectives can be interchanged, although the powers will not be equivalent (approximately 10% difference). All 20X to 100X objectives have spring-loaded (retractable) front ends in order to prevent slide damage. Oil immersion is recommended for all 100X objectives in order to achieve an NA higher than 1.0 (for typical use: low viscosity 150 cps, 0.5 oz. tube with nd=1.515).
