Suitable for applications such as magnifying lenses and focusing lenses! It is ideal for compact optical systems.
"Double convex lenses" have a positive focal point and are mainly used for magnifying images and focusing applications. Compared to plano-convex lenses, they have a stronger power to refract light, making them suitable for compact optical systems such as lighting systems, telescopes, monoculars, microscopes, binoculars, cameras, and projectors. In the case of the human eye, they are used to create virtual images, while in the case of photographic film or optical sensors, they are used to generate real images. 【Specifications】 ■Material: B270, BK-7 ■Refractive Index: B270 (1.5230/nd, 1.5251/ne), BK-7 (1.51680/nd, 1.51872/ne) ■Design Wavelength: 587.6nm (d line) ■Chamfering (45°) with protective chamfer ・φ3 to φ5: 0.1mm ・φ10 to φ100: 0.2mm *For more details, please download the PDF or feel free to contact us.
