What are aspheric lenses?
Aspheric lenses are optical components with complex curved shapes designed to eliminate spherical aberrations, thereby providing sharper images and better beam quality. Compared with traditional spherical lenses, aspheric lenses excel in imaging and beam shaping and are widely used in beam collimation for optical fibers and laser diodes.
Aspheric Lens Products from MOK Optics
MOK Optics offers a variety of aspheric lenses with surface treatment options of molded, CNC polished, and MRF polished. Each type of lens has its own unique advantages and is suitable for different application scenarios.
Molded Aspheric Lenses
Molded aspheric lenses are manufactured through high-precision molds, with lower production costs and faster delivery times. They are suitable for mass production and perform well in applications that do not require high optical performance. However, the surface quality and beam transmission efficiency of molded lenses are slightly inferior to those of CNC polished lenses.
CNC Polished Aspheric Lenses
CNC polished aspheric lenses are machined using computer numerical control technology, which enables larger sizes and higher surface quality. They excel in preserving the M-squared value of the input beam and are suitable for use in high-precision optical systems. The surface smoothness and optical performance of CNC polished lenses make them the first choice for many high-end applications.
MRF Polished Aspheric Lenses
MRF (Magnetorheological Polishing) technology provides true diffraction-limited spot sizes and lowest wavefront errors. This high-precision polishing method makes MRF polished aspheric lenses stand out in applications that require extremely high optical performance. They are suitable for fields such as scientific research, medical imaging, and high-end laser systems.
Other Optical Products
In addition to aspheric lenses, MOK Optics also produces a variety of optical components to meet different needs:
Non-polarizing beam splitters: used to separate beams of different polarization states, widely used in laser systems.
Polarizing beam splitters: used to control the polarization state of the beam and improve the efficiency of the optical system.
