zoom objective lens

The MV- and M- are microscope objective lenses that have been adjusted for a rear conjugate at 160mm and 187mm, respectively. The MV- series is the preferred choice for standard laboratory applications. The M- series has a range of powers between 5x and 60x either as a complete or individual set.

These also have infinity-corrected objectives that have a rear conjugate at infinity and are best for use as input lenses in applications where the best wavefront quality is needed. The infinity objectives have a range of power between 4x and 40x. Reflective microscope objects are actually Cassegrains based on the Schwardchild design.

It has astigmatic, spherical and negligible coma aberrations and zero chromatic aberration. They also have 15x and 36x objectives that are broadband coated with aluminum and over coated with the magnesium fluoride or MgF2. They are usable and available from 200nm to 20?m.
