QTY. 1. 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, AND BLOOD SMEARS.  0.65: THIS IS THE NUMERICAL APERTURE (NA), 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.The infinity symbol. Light leaves the back of this objective as parallel rays. It requires a microscope frame equipped with a tube lens to focus the image onto the eyepiece or camera sensor. You cannot mix this lens with older microscopes that have a "160" or "170" millimeter stamp
