National Optical 211-RLED Monocular Cordless LED Microscope

Description

• A new standard of precision optics, highly engineered mechanics and very rugged construction, all at a 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 rechargeable LED illumination system provides optimum image brightness, virtually no bulb heat and has a 50,000-hour rated bulb life
• OPTICAL SYSTEM Widefield 10x eyepiece with pointer
• Accepts optional #965-160 eyepiece reticle
• 45° inclined monocular viewing head
• DIN standard 4x (0.10 N.A.), 10x (0.25 N.A.), 40xR (0.65 N.A.) objectives are supplied for 40x, 100x and 400x magnification
• All are achromatic, parfocalled, parcentered and color-coded
• 4-hole objective turret, reverse position, ball-bearing mounted for smooth, precise changes in magnification
• Camera port integrated into head for attachment of optional Moticam camera C-mount lens and 1.5 mm wrench sold separately ILLUMINATION LED light rated up to 50,000 hours life, illumination equal to a 20 watt tungsten bulb
• Batteries allow up to 500 recharges, for a total of 20,000 to 25,000 hours use from a single set of 3 AA rechargeable nickel hydride batteries
