An Epi-Fluorescence attachment allows easy observation of living cells under fluorescence methods such as GFP. A Coaxial Episcopic Illuminator using a 12V/150W Fiber Optic Light Source offers bright illumination over the entire surface of your sample. Exclusive OCC (Oblique Coherent Contrast) lighting allows observation of samples with extremely low contrast in high relief. Phase differences can be observed to 1/30 of a wavelength of light.

By using a beam splitter and adapter, a digital still camera or a CCTV camera can be attached. The P-IBSD Beam Splitter D has two ports allowing one photomicrographic system and one CCTV camera to be mounted at the same time. The light to the rear port can be switched between 0%, 50%, or 100%, and the light to the side port is switchable between 0% and 50%. With the P-IBSS Beam Splitter S, the light to the side port is switchable between 0% and 50%.

The parallel optical system of the SMZ800 has a 6.3:1 zoom ratio with clickstops at intervals from 1x through 6x. It features a zoom range of 1x to 6.3x and total magnification (depending on eyepiece and objective used) is 5x to 378x.

Eight objectives are available from economical achromat objectives to highly corrected Apochromats and a 1x ERGO focusing objective.

The inclination of the standard eyepiece tube is 20°, allowing the operator to make observations with a straight back. This reduces fatigue during long hours of operation by lessening strain on the neck, shoulders, and back.

With the tilting eyepiece tube, the eye-level can be adjusted within a maximum range of 157mm (6.2 in). This is accomplished by swinging the eyepieces up 180° as well as tilting them. The tilting eyepiece tube makes it possible to adjust the eyepiece inclination between 0° and 30°.

Nikon has also developed a new ergonomic objective (Plan 1x ERGO) that can be extended or retracted up to 40mm (1.6 in) to obtain the optimum operator eye-level without changing the magnification or working distance. Moreover, the low eye-level eyepiece tube enables a comfortable observation posture even when using a diascopic stand or when an intermediate tube is inserted. An eye-level riser is also available.

The Plain Focusing Stand features a low profile for easy handling of samples. Furthermore, the base has a wide front and smooth curve, allowing operators to work while comfortably resting their arms in a natural position.

The stage glass in the diascopic stand has been enlarged. This allows large Petri dishes to slide over its smooth surface with ease, making it possible to view samples up to their periphery. You can also rest your hands on the armrest to reduce stress while working.

The new Diascopic Stands, models C-DSD, C-DSS, and C-BD, each have a built-in power supply in a space-saving design. These stands also feature their own fine focus knob at the front of the base to easily make critical adjustments of focus. Model C-DSD uses Oblique Coherent Contrast (OCC) illumination and is ideal for observing colorless, transparent samples, while the C-BD uses a seven-sided toroidal mirror to reduce stray light up to 1/5 that of conventional equipment.
