The APMQ lens acts to shorten the combined focal length of the system without introducing additional coma or spherical aberration.To introduce no spherical aberration or coma, the APMQ lens design must be matched to the spherical wavefront generated by the preceding LAPQ lens. This requirement determines the front and back radii and center thickness of the meniscus lens. Also, the APMQ lens must be properly spaced from its companion laser aplanat. Therefore, APMQ and LAPQ lenses are used in pairs. CVI Laser Optics provides each APMQ lens premounted in a housing that assures proper spacing and orientation with its paired LAPQ lens.APMQ lenses can be ordered with their companion laser aplanats or separately. This gives you the ability to change the focal length of an existing system at a later time.

Spherical Lenses

The APMQ series of aplanatic meniscus lenses shorten the focal length of the LAPQ series positive laser aplanats while maintaining the minimization of the aberrations inherent in the LAPQ series lenses.An LAPQ/APMQ combination is an f/3.3 focal system made up of reasonably priced standard components.
