Designed for specific applications, they combine specific geometries and optical performance advances.
Their surface is not spherical but calculated for eliminate optical aberrations and optimize image quality.
They offer improved performance while reducing the number of optical elements in a system, and are indispensable in photographic lenses, medical devices and precision imaging.
Assembled from two lenses made of different materials (crown and flint glass), they correct chromatic dispersion and guarantee sharp images over a wide range of wavelengths, they are widely used in microscopy, scientific observation and color measurement optics.
Cylindrical plano-convexes concentrate light to create a luminous line (lighting, scan, laser).
Cylindrical plano-concaves disperse light to homogenize a beam. They are essential for profile measurement systems, linear projection and laser detection.
Fresnel lenses take the principle of a spherical lens and divide it into concentric annular zones.
They are much lighter and thinner, while retaining the same optical power.
Used in spotlights, headlamps, solar systems and handheld devices, they enable effective focus with a minimum footprint.
