Evident SZX-BI45 Binocular 45 Degree Inclination Element

Description

Positioning the viewing axis at a standard 45-degree angle, the Evident SZX-BI45 Binocular 45 Degree Inclination Element directs parallel Galilean light paths directly to user oculars. Interpupillary adjustment covers 50mm to 76mm. The fixed 45-degree viewing angle matches standard-height desks perfectly, though operators on tall barstools may prefer a flatter 30-degree inclination.

A cast-aluminum optical housing features a circular dovetail mount coupling directly onto SZX zoom bodies, weighing just 0.9 kg. Internal prisms split parallel beams from Common Main Objective systems into dual binocular paths without optical vignetting. The observation tube incorporates Siedentopf interpupillary distance tracking across a 50mm to 76mm range, supporting standard WHSZ eyepieces while routing 100 percent of available light straight to the observer.

Key Features of Evident SZX-BI45 Binocular 45 Degree Inclination Element

Routine inspection laboratories, biology classrooms, and assembly benches install this binocular tube to achieve an ergonomic viewing angle when microscopes sit on standard bench surfaces. Routing all transmission directly to the eyepieces maximizes image brightness on dim, unstained specimens without camera beam splitter loss.

• Fixed 45-degree optical path inclination optimized for standard laboratory desk heights
• Galilean Common Main Objective light path routing preserving distortion-free stereoscopy
• Siedentopf interpupillary adjustment spanning 50mm to 76mm for customized user fit
• Direct optical transmission routing 100 percent of light to oculars without splitter loss
• Precision circular dovetail connection with secure thumb screw locking mechanism
• Durable cast-aluminum housing weighing just 0.9 kg to minimize column load
• Compatible with standard WHSZ series high-eyepoint widefield eyepieces

Galilean Parallel Optics & Optical Transmission

Designed for Common Main Objective stereo systems, the internal optical prisms accept parallel infinity beams from SZX zoom bodies, preventing convergence distortion and image keystone effects. Because the tube excludes camera splitters, it delivers 100 percent of gathered photons directly to your retinas, maximizing contrast when screening faint fluorescence or observing low-contrast transparent specimens under oblique transmitted light. Anti-reflective coatings on all internal air-to-glass boundaries eliminate ghosting and internal flare.

Dovetail Mounting & Siedentopf Mechanics

Securing the optical head takes seconds via the precision-machined circular dovetail, which locks rigidly with a single brass-tipped set screw to protect finish coatings. The Siedentopf interpupillary mechanism rotates smoothly between 50mm and 76mm without altering tube length or tube focus, allowing multi-user laboratories to adjust ocular spacing without losing specimen parfocality.

• Circular dovetail ring drops cleanly onto SZX7, SZX10, and SZX16 zoom bodies
• Siedentopf interpupillary movement maintains tube length and focal alignment during adjustment
• Lightweight 0.9 kg casting prevents excessive top-heavy mass on boom stand mounts
