Microscope Objectives
Ealing Microscope Objectives both Reflecting Objectives and Standard Laboratory Objectives are known for their unique optical properties.
In Reflecting Objectives the use of all-reflecting construction ensures freedom from chromatic aberration. They are based on a Schwarzschild two-mirror design consisting of a small convex primary mirror and a larger concave secondary mirror. By choosing appropriate values for the mirror radii of curvature and their separation, it is possible to correct three of the primary monochromatic aberrations for the system. The aberrations that are corrected are the primary spherical aberration, primary coma and primary astigmatism.
In addition to their correction for monochromatic aberrations, Reflective Microscope Objectives have many advantages over refracting objectives of equivalent aperture and focal length:
- Ideal for laser beam delivery
- Freedom from chromatic aberration
- Long working distances with high magnifications
- Large numerical aperture

Laboratory Microscope Objectives
These microscope objectives will work with all major brands of microscopes designed for a 160 mm-tube length. They are intended for general laboratory use in the visible spectrum. All optical surfaces are AR coated for maximum throughput.
