Jenoptik produces spherical and aspherical polymer fresnel lenses as individual items or in small batches using ultra-precision lathes. Polymer fresnel lenses are divided into a set of concentric annular sections. The individual sections ...

Biconic lenses have two different radii on one surface. It is possible to make a biconic lens with spherical curves or aspheric curves, depending on the application and need to eliminate aberrations. Biconic lenses are used to produce ...

A Fresnel lens is used instead of the curved surface of a traditional lens, it also incorporates a series of concentric grooves which have been molded into the surface of a thin and light sheet of plastic. Each of these grooves is an ...

Diameter: 1 mm - 300 mm

mini axicon lens Axicon lens also known as conical lens and plano convex axicons. It can be used to convert a parallel laser beam into a ring, to create a non diffractive Bessel beam or to focus a parallel beam into long focus depth. ...

Diameter: 12.5 mm - 50.8 mm

Can be made from most optical materials Two axicons together produce a thick-walled hollow "pipe" of light. An axicon followed by a spherical lens produces an annular focus. The axicons can be used to convert a parallel laser beam into ...

Diameter: 0.8 mm - 350 mm
Wavelength: 190 nm - 3,000 nm

Singlet Lens is a transmissive optical device which affects the focusing of a light beam through refraction and only composed of a piece of optical glass lens with the simplest near-field conjugate structure system. According to the ...

Diameter: 25.4 mm

HIGH PRECISION AXICON LENSES UNCOATED SKU : AXC-U In contrast to aspheric lenses, the shape of an axicon resembles a cone. The conical shape of the axicon generates a ring-shaped beam profile. The diameter of the ring beam depends ...

Double convex axicons stand for optical components with a convex conical surface in combination with a convex spherical surface. Optical axicons are optical components with a conical surface on one side and plan or spherical surface ...

Fresnel lenses replace the curved surface of a conventional lens with a series of concentric grooves, moulded into the surface of lightweight plastic sheets. These grooves act as individual refracting surfaces when viewed in cross section. Our ...

Diameter: 1.5 mm - 300 mm

Triplet Lenses A triplet lens is cemented by one piece of crown glass with low refractive index and two pieces of flint glass with high refractive index, normally the cemented lens can eliminate spherical chromatic aberration of axial ...

Anti-reflecting coatings are designed to reduce Fresnel reflections from optical component’s surface and therefore improve the overall transmittance of optical system, where the component is used. Reflection of common glass surface at ...

The Powell lens has an advantage over cylindrical lenses because later one produces a poorly illuminated line, limited by the non-uniform Gaussian laser beam. Huge spherical aberration redistribute light along the line, decreasing the ...

These are the Fresnel lenses for the Murata pyroelectric infrared sensors. Select the lens which is best suited to the required detection area. Select the lens according to the detection area and mounting location. Check the lens ...
