magniplus doublets cylinder

Magniplus doublets with a cylinder
are made of three lenses: two of them at 40 mm diameter for spherical correction (designed for correction of geometric aberrations throughout the filed of view) and the other one at 42 mm diameter for cylindrical correction. All the lenses have antireflection coating on all surfaces.

Working distance ranges from 120 mm to 25 mm for spherical correction.

We can supply any combination of spherical correction with a cylinder within the ranges mentioned.

They are perfect for people with accommodation failure at very short distances and cylindrical correction needs.
