λ/8 Optical Lenses

Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. An Achromatic Lens, which... [See More]

These lenses are symmetrical with equal radii on both sides. The biconcave lenses are often used to expand light beams or to increase focal lengths in optical systems, and are normally used in combination with other lenses. Among the many devices utilising biconcave lenses are laser beam expanders,... [See More]

• Center Thickness: 1.7 to 4.8

A cemented cylindrical lens can minimize chromatic aberration, so it can be used to focus a single direction of a multi-color light beam. Unlike a spherical lens that produces a point focusing spot, a cylindrical lens can produce a linear focusing spot. Our cylindrical achromatic doublets are... [See More]

These simplest form lenses have flat surface on one side and spherical surface on the other. They are widely used in telescopes, microscopes, collimators, optical transceivers, magnifiers, condenser systems and eyepieces. Plano convex lens made of BK7, UV FS (UV grade Fused Silica), CaF2 (Calcium... [See More]

• Focal Length: 20 to 10000

• Lens Type: Cylindrical Lens
• Center Thickness: 2.1 to 12.3

A cylindrical lens is typically used to focus, condense or expand incoming light. A cylindrical lens has one cylindrical surface, causing light to be focused in a single dimension or axis. It can also be used to expand the output of a laser diode into a symmetrical beam. Cylindrical lenses are... [See More]

These lenses are thicker at the edge than in the centre and flat on one side. The plano-concave lenses are used to expand light beams or to increase focal lengths in optical systems. They are often employed for beam expansion of high peak power pulsed lasers. A beam incident on a concave surface... [See More]

A double concave lens has negative focal length, thereby causing collimated incident light to diverge. Double concave lens has equal radius of curvature on both side of lens. They are generally used to expand light or increase focal length in existing system, such as beam expander and projection... [See More]

• Focal Length: -2000 to -50

• Lens Type: Spherical Lens
• Center Thickness: 2 to 20

Biconvex lenses are all symmetrical, having equal radii on both sides. They are recommended for virtual imaging of real objects, and for positive conjugate ratios from 0.2 up to 5. Outside of this ratios range plano-convex lenses are usually more suitable. Biconvex lenses are used as magnifiers,... [See More]

• Lens Type: Cylindrical Lens
• Center Thickness: 2.2 to 16.2

The double convex lens is symmetrical across both its horizontal and vertical axis. Each of the lens' two faces can be thought of as originally being part of a sphere. The fact that a double convex lens is thicker across its middle is an indicator that it will converge rays of light that travel... [See More]
