The 161-P Dual Head Compound Microscope from National Optical is a four-objective dual viewing head microscope designed for university students and laboratory use. Plan achromatic DIN objectives maximize image clarity, produce a flat field of view, 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-P 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.
