Diaprojektor KAISER 2010 — kompaktné 3-násobné zväčšenie, 75×105×60 mm, 1,5 V batéria

The KAISER 2010 slide projector is a compact, battery-operated viewer designed for quick inspection of 35 mm framed slides and 5×5 cm (2×2 in.) mounted transparencies. Its small housing, approximately 75 × 105 × 60 mm, makes it easy to carry and use in locations where mains power is unavailable. The unit uses a spherical lamp and an optical lens assembly that provides 3× magnification for clear, immediate previews of slide content.

Advantages

The device combines portability and straightforward operation: it runs on two AA 1.5 V batteries, so no external power supply is required, and its hinged prop allows stable positioning during viewing. The spherical lamp and lens system deliver bright, evenly illuminated images suitable for rapid checks, archiving tasks and quick selection of slide material. Compact dimensions and lightweight construction make it suitable for field work and situations with limited workspace.

Suitable for

• Quick previewing of 35 mm framed slides and small mounted transparencies
• Archival checks and sorting of slide collections
• Portable image inspection during on-location shooting or travels
• Educational demonstrations where a small, simple slide viewer is needed

Key specifications

• Magnification: 3×
• Intended film format: 35 mm framed slides, mounted transparencies 5×5 cm (2×2 in.)
• Optical lens size: 63 × 53 mm
• Illumination: spherical lamp, 2.5 V 0.3 A, E10 type
• Power source: 2 × AA (1.5 V) batteries (not included)
• Housing dimensions (W×H×D): approx. 75 × 60 × 105 mm

How to use

Open the hinged prop and place the slide into the designated viewing slot or frame holder. Install two AA 1.5 V batteries in the compartment following the polarity markings. Switch on the lamp to illuminate the slide and view the enlarged image through the lens at the viewing aperture. Adjust the position of the slide manually to center the image; the fixed optical system provides a stable 3× enlargement without additional focusing mechanisms.

Recommendations

Use fresh alkaline AA batteries for consistent brightness and replace the lamp with the specified 2.5 V, 0.3 A, E10 spherical bulb when illumination declines. Avoid exposing the device to strong moisture or extreme temperatures; store slides flat and handle mounted slides by the edges to prevent fingerprints.
