Lenses

Lense is the most basic optical component, It collects light from a source and refracts that light to form a usable image of the source. Lenses have many applications, ranging from the simple collection of the scanning of laser beams to precise imaging and image transfer.

 

MOK Optics have strong capability to produce vairous of lenses

Plano-Convex lenses are the best choice for focusing parallel rays of light to a single point. Our plano-convex lenses are fabricated from N-BK7, UV fused silica, N-SF11,Germanium,Silicon etc.

Plano-concave lenses diverge a collimated beam from a virtual focus and are commonly used to balance out aberrations of other lenses in the system. MOK Optics provides plano-concave lenses fabricated from N-BK7, N-SF11, UV-fused silica, CaF2,ZnSe etc.

A biconvex lens, also known as a double convex lens, is a type of lens that is thicker in the middle and thinner at the edges, with both surfaces curved outwardly. Our biconvex lenses are fabricated from N-BK7, UV fused silica, N-SF11,Germanium,Silicon etc.

A biconcave lens, also known as a double concave lens, is a type of lens that has two inwardly curved surfaces, causing parallel rays of light passing through it to diverge. Biconcave lenses are essential components in optics for diverging light rays and have specific applications in optical systems where diverging lenses are required. Our biconcave lenses are fabricated from N-BK7, UV fused silica, N-SF11,Germanium,Silicon etc.

A meniscus lens is a type of lens that has one convex surface and one concave surface, similar to the shape of a lens used in eyeglasses,offering both converging and diverging optical properties depending on their curvature and orientation.

An achromatic lens, also known as a doublet lens, is a type of lens designed to reduce chromatic aberration. It is a lens consisting of two cemented elements made of different materials. Chromatic aberration is a phenomenon in optics where different colors of light are focused at different distances, causing color fringes and blurring in images. The achromate lense offers superior correction of spherical aberration in monochromatic applicaitons. 

Cylindrical lenses are prescribed to correct astigmatism. Cross cylinder, which is a combination of two cylindrical lenses with equal strength and opposite power, is used in subjective refraction to diagnose astigmatism.

Rod lenses are lenses having the geometrical form of a cylinder. They can be used as cylindrical lenses for beam collimation, focusing and imaging.

The Powell lens, which we can also call a laser generating lens, can create a uniform straight laser line by spreading a collimated beam in a one-dimensional fan shape. They are use in alignment, machine vision systems, construction, process control and lower power lasers.

Key specifications of powell lense:

Diameter:  6-40mm
Fan angle: 3°-120° ( 3°,5°,10°,15°,30°,45°,60°,75°,90°,100°,120° )
Laser beam diameter:  0.5mm – 18mm
Working wavelength:  405nm – 950nm
Line homogeneity:  80% -90%

Aspherical lenses are available molded, CNC-polished,either with or without anti-reflection (AR) coatings. Aspheres are often employed to collimate light exiting a fiber or laser diode. The surface of an asphere is designed to eliminate spherical aberration.
