These microscope objectives are for use without a cover glass. Biological microscope objective lenses are normally designed for use with a thin glass cover slide placed on top of the sample being examined. Biological and medical microscope objectives specifically correct this and are therefore not suitable for other uses.
These microscope objectives are ideal focusing lenses for low power lasers such as HeNe, HeCd and N2. The lenses are Anti-Reflection coated. The objectives are also fully colour corrected for use throughout the visible. These precision achromatic objectives cover a range of numerical apertures. They are housed in conventional microscope barrels and are fitted with a standard RMS microscope thread.
