MAGUS MA20 20х/0.40 ∞/0.17 Infinity Achromatic objective lens

This achromatic objective has 20x magnification and a resolution limit of 0.69 µm. The lens is infinity corrected. It can be used for examining 1 µm and smaller samples in a wide field of view. Suitable for laboratory testing of biological fluids such as blood or urine (counting the number of leukocytes, red blood cells, cylinders).

The MAGUS MA20 20x/0.40 objective can be used with eyepieces between 10x and 20x. The lens corrects chromatic aberration in the blue and red ranges, spherical aberration in the green range, and field curvature at 65% of the field diameter. Use a 0.17 mm thick cover glass during observations.
