The INV-3 Inverted Microscope is designed for observation of living cells and specimens in culture vessels such as flasks, Petri dishes and multi-well plates. It features an infinity optical system, 30° inclined trinocular head, ELWD condenser, phase-contrast capability, long-working-distance objectives and an attachable mechanical X-Y stage.

Product Overview

The INV-3 Inverted Microscope is designed for routine and research observation of specimens that are difficult or impractical to transfer onto conventional microscope slides. Its inverted optical configuration places the objectives below the stage, making it suitable for examining specimens contained in culture flasks, Petri dishes and multi-well plates.

The microscope uses an infinity optical system and a 30° inclined trinocular head with an interpupillary distance adjustment of 48–75 mm. The trinocular arrangement is suitable for visual observation together with image documentation using a compatible microscope camera.

For specimens contained in vessels with significant working height, the microscope incorporates an ELWD condenser with NA 0.3 and 72 mm working distance. Removing the condenser provides approximately 150 mm of free space, according to the specified configuration.

The optical system includes an EW10X/20 extra-wide-field eyepiece, a 40X LWD Infinity Plan objective and 10X/20X Infinity Plan Phase objectives. A fixed 10X–20X phase annulus plate enables phase-contrast observation of suitable transparent specimens.

An attachable mechanical stage provides 120 × 78 mm X-Y movement, while coaxial coarse and fine focusing provides controlled adjustment with 0.002 mm fine division.
