Model 155

A new standard of precision optics, highly engineered mechanics and very rugged construction, all at little more cost than a budget microscope. Objective turret (nosepiece) is in reverse position to permit easier changing and positioning of specimen slides. Preferred by teachers, the 5-watt fluorescent illumination system provides optimum image brightness, virtually no bulb heat and has a 10,000-hour rated bulb life.

OPTICAL SYSTEM

• Widefield 10x eyepiece with pointer. Accepts optional #965-160 eyepiece reticle.
• 45° inclined monocular viewing head rotates 360° for easy sharing by more than one student.
• DIN standard 4x (0.10 N.A.), 10x (0.25 N.A.) and 40xR (0.65 N.A.) objectives are supplied for 40x, 100x and 400x magnification. All are achromatic, parfocalled, parcentered and color-coded.
• 3-hole objective turret, reverse position, ball-bearing mounted for smooth, precise changes in magnification.

ILLUMINATION

• Built-in 5-watt fluorescent illumination, delivers greater light and longer life than standard 20-watt tungsten bulb. Virtually no base heat. 10,000 hour rated bulb.
• Base mounted on/off switch, heavy-duty 3-wire grounded electrical system and plug.
• 0.5A time delay fuse.

FOCUSING

• Separate low position coarse and fine focusing controls.
• Stage moves up or down, eyepiece and body remain fixed.
• Slip clutch prevents damage to focusing system.
• Tension adjustment eliminates stage drift.
• Safety rack stop prevents damage to slides and objective lenses.

STAGE

• Large 120mm x 125mm (4-3/4 in. x 5 in.) stage, with locked-on spring mounted stage clips, drilled and tapped to accept optional mechanical stage (Model 155-MS).
