Vanguard Compound Microscope, Model 1400PH Series, Phase Contrast

The 1400PH Series Compound Microscopes are the flagship of the VanGuard Microscope line. Combining top performance with highly-advanced features and optics, the 1400 Series models produce images of the utmost in clarity.

Viewing Head. Binocular or trinocular (Seidentopf) heads rotate 360° and are inclined at 30°. All models feature interpupillary and dioptric adjustment. The trinocular heads feature a sliding main prism (30 / 70 split) to provide full-time imaging when the vertical tube is in use (70% of the image to the vertical tube and 30% to the viewing eyetubes).
Nosepiece. Quadruple or quintuple, reversed, ball-bearing nosepiece with high-grade lubricant and positive stops. The nosepiece is reversed (inward-facing) to allow for easier manipulation of slides and to aid in keeping the objectives clean.
Objectives. Plan achromatic objectives come standard on the phase contrast models. All objectives are made to DIN standards and are coated.
Stage. Delivering a high level of fluid motion control and longevity, the stage measures 140x140mm. Features a removable spring-clip slide holder and a chemical-resistant finish. Motion is controlled by a right-hand, low-position coaxial control and is driven by a rack and pinion system.
Focusing Movement. Coaxial, ultra low-position coarse and fine focus controls feature a 40mm focusing range and are graduated to 2 microns per division. Fitted with tension adjustment and safety autostop.
Condenser. These Phase Contrast Models come with a 1.25 N.A. Zemike condenser with phase annulus rings for 10X, 20X, 40X AND 100X, . All condensers are mounted on a rack and pinion focusing mechanism and feature spring-loaded centering knobs and an iris diaphragm with a swing-in filter holder.
