N-BK7 & Fused Silica Double Convex Lenses

Double Convex Lens

Crysmit have more than 10 years of experience in lens manufacturing, design, and optical precision assembly. CRYSMIT provide these lenses with the material of N-BK7, fused silica, sapphire, CaF2, and other glass raw material.
A Double Convex Lens has two outward curves, It focuses parallel light rays to a point, forms real images, and has a positive focal length. When positioned correctly, it can magnify an image. These lenses can exhibit spherical and chromatic aberrations, though these can often be minimized or corrected. These lenses are widely used in various optical systems and devices.

Know about the Features and application of Double Convex Lens ?

A Double Convex Lens, also known as a Biconvex Lens, has two outwardly curved surfaces that bulge outwards. Here are the key features of a double convex lens:

Focusing Light: Double Convex Lenses are designed to bend parallel light rays inward and focus them to a single point. This makes them useful in a wide variety of applications where light needs to be focused, including microscopes, telescopes, and cameras.

Forming Real Images: Double Convex Lenses are capable of forming real images that can be projected onto a screen or a sensor. This property is useful in many optical systems, particularly those involved in imaging.

Positive Focal Length: Double Convex Lenses have a positive focal length, meaning they focus light to a point.

Magnification: When placed at the correct distance from the eye or an optical device, a double convex lens can magnify an image. This makes them useful in applications such as eyeglasses, binoculars, and magnifying glasses.

Aberration: Double Convex Lenses can suffer from spherical and chromatic aberrations. However, these aberrations can often be corrected or minimized with proper lens design and by combining the lens with other types of lenses.

Material Variety: Like other types of lenses, double convex lenses can be made from a wide range of materials, each affecting the lens's properties, such as its refractive index, dispersion, and transmission range.

In conclusion, double convex lenses are versatile and widely used in many optical systems due to their ability to focus and magnify light. They are found in a broad range of devices from simple magnifying glasses to advanced imaging systems.
