Greenough optical system description
Greenough) 10 degree angle in Greenough optical system
Convergence fixes an excellent image plane with a large depth of field.
V-shaped optical path ensures slim zoom lens body
Suitable for integration into other systems or used alone
Eyepiece description:
OLYMPUS special eyepiece design has pupil aberration control and appropriate viewpoint positioning.Ensures fast and comfortable observation.
And the excellent optical coating technology can present true color images with exquisite details
The SZ61 has a magnification range from 6.7 to 45x (using a 10x eyepiece), with a zoom ratio of 6.7:1.
The advanced optical system enables fast and comfortable observation at the most suitable magnification.
SZ51 magnification range from 8X to 40X (using 10X eyepiece)
zoom ratio 5:1.
10-degree angular convergence Greenough optics in the imaging path provides excellent image flatness with considerable depth of field
The eyepieces feature pupillary aberration control and are properly positioned at the eye point for fast and comfortable viewing.
The SZ61 and SZ51 zoom bodies offer two different magnification ranges. They are ergonomically designed for use with standard 45-degree viewing tubes, models with 60-degree tilt tubes (SZ61-60/SZ51-60) are suitable for special applications with zoom bodies that must be tilted for use with other equipment or for mounting in universal stand.
