The kits containing lenses with different focal lengths and configurations providing a selection of the most demanded lenses. Focal lengths of plano-convex and biconvex lenses range from 25 to 1 000 mm. Plano-concave lenses cover a focal distance f...

These lenses are symmetrical, having equal radii on both sides. 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 util...

These lenses are thicker at the edge than in the centre and flat D 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 pu...

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 this ratio range plano-convex lenses are usually more suitable...

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. Standard lenses have a rang...

Positive or negative focal length lenses have different radii or curvature on both sides whereas neutral meniscus lenses do not focus light. Meniscus lenses are used in applications where distortion of the beam has to be reduced. They are used for fo...

Double concave or Biconcave lenses are symmetrical with equal radii of curvature on both sides. The biconcave lenses are used in optical systems in combination with other lenses. These lenses also work as beamexpanders, optical character readers, vie...
