Product Details
Flat field semi complex achromatic lens , Achromatic Objective Lens
Objective lens is the most important optical component of
microscope. It uses light to image the tested object for the first
time, which is directly related to and affects the imaging quality
and various optical technical parameters. It is the primary
standard to measure the quality of a microscope.
The objective lens has complex structure and precise manufacture.
It is usually composed of lens groups. Each lens is separated from
each other by a certain distance to reduce aberration. Each group
of lenses is glued by one or more lenses of different materials and
parameters. The objective lens has many specific requirements, such
as axis closing and focusing.
There is a difference between microscope objective and eyepiece in
participating in imaging Objective lens is the most complex and
important part of microscope. It works in wide beams (large
aperture), but the inclination angle between these beams and the
optical axis is small (small field of view); The eyepiece works in
a narrow beam, but its inclination is large (large field of view)
When calculating the objective lens and eyepiece, there is a great
difference in eliminating aberration.
