MICROSCOPE OBJECTIVE LENS PLAN 40 X /0.65 /0.17. PLAN: THIS

MICROSCOPE OBJECTIVE LENS PLAN 40 X /0.65 /0.17. PLAN: THIS MEANS THE LENS IS A PLAN ACHROMATIC OBJECTIVE. IT FEATURES ADVANCED OPTICAL CORRECTIONS THAT FLATTEN THE FIELD OF VIEW. UNLIKE STANDARD LENSES WHERE THE EDGES OF THE IMAGE LOOK BLURRY WHEN THE CENTER IS FOCUSED A PLAN LENS ENSURES THE ENTIRE IMAGE IS SHARP AND IN FOCUS FROM EDGE TO EDGE . 40 X: THIS IS THE LINEAR MAGNIFICATION POWER. IT MULTIPLIES THE SIZE OF THE SPECIMEN BY 40. WHEN PAIRED WITH STANDARD 10X EYEPIECES THE MICROSCOPE PROVIDES A TOTAL MAGNIFICATION OF 400X WHICH IS IDEAL FOR STUDYING DETAILED CELL STRUCTURES BACTERIA WHICH MEASURES THE LENS'S LIGHT-GATHERING ABILITY AND RESOLVES FINE DETAIL. AN NA OF 0.65 PROVIDES A STRONG BALANCE OF HIGH RESOLUTION AND A WORKABLE DEPTH OF FIELD WITHOUT NEEDING IMMERSION OIL. 0.17: THIS SPECIFIES THE REQUIRED COVER GLASS THICKNESS IN MILLIMETERS (0.17 MM). THE LENS IS OPTICALLY OPTIMIZED TO LOOK THROUGH A STANDARD #1.5 COVERSLIP. USING A SLIDE WITH NO COVER GLASS OR ONE THAT IS TOO THICK WILL INTRODUCE SPHERICAL ABERRATION AND DEGRADE IMAGE CLARITY.
