Leica 5x/0.12 PH 0 Infinity/-/B Microscope Objective Lens 506303
Phase contrast at 5x, which most objective ranges skip entirely
Phase rings are common at 10x, 20x and 40x and rare at 5x, because the assumption is that low magnification means survey work in brightfield. In practice, scanning a flask or a plate for coverage and morphology at 5x under phase is faster than doing it at 10x, and this is the objective that makes it possible.
N PLAN is Leica's flat-field achromat line, infinity corrected, marked PH 0 with a red identification band and MPN 506303.
Where it earns its place
- Fast phase contrast scanning of flasks and plates before moving in
- Confluence and morphology checks across a wide field
- Completing a PH 0 position on a Leica turret
- Low-magnification phase on stands whose range starts at 10x
