Its correction collar compensates for cover glass and vessel bottom thicknesses from 0 to 2.0mm, with an 8.2–6.9mm working distance that accommodates thick-bottomed plastic dishes, flasks, and well plates. High transmittance from near-UV to near-IR makes it an excellent choice for fluorescence and calcium imaging, while DIC N1 compatibility and support for brightfield, darkfield, and simple polarization make it a versatile everyday objective on Nikon inverted microscopes.\u003c\/p\u003e\n\n\u003ch3\u003eCondition\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Refurbished\/Used (This product has been inspected and verified to meet manufacturer specifications)\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra-long working distance (ELWD): 8.2–6.9mm\u003c\/li\u003e\n  \u003cli\u003eCorrection collar for cover glass and vessel bottoms from 0 to 2.0mm\u003c\/li\u003e\n  \u003cli\u003eSuper Plan Fluor optics with high transmittance from near-UV to near-IR\u003c\/li\u003e\n  \u003cli\u003e0.45 numerical aperture for bright fluorescence imaging at 20x\u003c\/li\u003e\n  \u003cli\u003eDIC N1 compatible;
