Objectives

Gillett and Sibert (G&S) were probably the last of the microscope manufacturers in the UK. During the 1960's they were stalwarts of well-engineered microscopes used in most pathology laboratories. Their original objectives were relatively short in length. This is a x50 oil immersion lens with a numerical aperture of 0.95 and corrected for 160mm tube length with a standard RMS screw thread. However, it is longer than their early objectives.

The name Zeiss needs no introduction and the quality of microscope objectives shows at very high power and also low power magnifications, simply because producing the right curvature lenses for both extremes is where the skill comes in. This is a x2.5 plan achromatic objective with a numerical aperture of 0.06, corrected for 160mm tube length with an RMS screw thread. A very good lens

Good Reichert objectives are getting a bit thin on the ground these days. This x45 with a numerical aperture of 0.65 with a standard RMS screw thread and is corrected for 160mm tube length. Good condition.

G & S had a simple mechanism for phase contrast illumination. For phase contrast a phase objective together with a phase condenser is required. Instead of needing to change the condenser G & S developed inserts for their bright field condensers that provided the necessary phase ring. The PH2 was for x40 objectives and this one is in good condition. Not many of these about these days.
