Nikon Metrology announced its newest Research StereoMicroscopes, the SMZ25 and the SMZ18, featuring a large zoom range, high resolution and bright epi-fluorescence. The SMZ25 and SMZ18 are suited for industrial applications, the company says.
The microscopes incorporate a newly developed zoom system (Perfect Zoom System), which enables a large zoom range of 25:1 (0.63-15.17x) and a high numerical aperture of 0.156 (for SMZ25, 1x Objective, at the highest zoom), allowing researchers to image both the entire sample as well as its microscopic details using just a single instrument.
The SMZ25 includes a 35mm field of view at the lowest magnification of 0.63x (using 1x objective, 10 x eyepieces), enabling users to image the entire 35mm sample. At the high magnification range, the company's high-performance objective lenses allow imaging of microscopic structures once considered too small to visualize on a stereo microscope, the company says.
The new epi-fluorescence attachment employs a fly-eye-lens that enables brighter and more uniform illumination across the entire field of view, even at the low magnification range. In addition, the signal-to-noise ratio has been improved by the incorporation of a short wavelength, high transmission lens in the zoom body.
The thinner LED diascopic illumination base increases the efficiency and ergonomics of sample manipulation and exchanging of samples, the company says. The new base also features Nikon's built-in OCC (Oblique Coherent Contrast) illuminator that produces high-contrast images of transparent samples such as ITO film.
