National Optical 161 Dual Head Compound Microscope

The 161 Dual Head Compound Microscope from National Optical is a four-objective dual viewing head microscope designed for university students and laboratory use. Achromatic DIN objectives minimize image distortions and deliver consistent views on all four magnification settings. The 100xR magnification objective can be oil-immersed for improved light transmission. The objectives are also parfocalled and parcentered, keeping the specimen in focus and centered in the field of view when the magnification is changed.

A user-friendly design complements the range of features that make the 161 series microscope a welcome addition to labs as well as classrooms. A 360° rotating monocular viewing head enables the inclined eyepiece to be shared with multiple viewers without having to move the microscope. A dual viewing head enables simultaneous use by two users, or the attachment of a camera using the optional c-mount adapter.

This configuration of the 161 has an individual focus dial for fine and coarse adjustments. The focus system also includes a slip clutch and rack stop that prevents mishandling. The 161 also features a rheostat-controlled 20W halogen light source and a mechanical stage with low-position x-y specimen adjustment controls. National Optical engineered this compound microscope to be easy to use yet feature-rich enough to employ advanced microscopy techniques. The 161 series microscope was built for reliable performance and is backed by the manufacturer's lifetime warranty.
