MAGUS SPH360 phase contrast device with Plan S-Apo Ph 4х/10х/20х/40х/60х H60 mm objective set

MAGUS SPH360 phase contrast device with Plan S-Apo Ph 4х/10х/20х/40х/60х H60 mm objective kit
For phase contrast microscopy

The MAGUS SPH360 phase contrast device consists of phase contrast slider compensators and a set of phase objectives.
The phase contrast device is used to study transparent, low contrast samples that are not visible in the brightfield. Staining kills living cells. The main advantage of the technique is that it can be used to study living unstained organisms in their natural state. The technique is applied in medicine, ecology, pharmacology, agriculture, etc.

Phase contrast slider compensators
The phase contrast slider compensator is installed in the slot of the condenser. The slider compensator is a plate with round holes. One free hole is for brightfield observations; the other holes have phase inserts that match the objectives in use. 
The phase contrast device includes two slider compensators. One has an insert that works in tandem with 10x, 20x, and 40x objectives; the other insert works in tandem with 4x and 60x objectives. The marking on the insert matches the objective in use.
The compensator allows you to easily switch from brightfield observations to phase contrast microscopy and vice versa.
The annular diaphragms of the slider are aligned with the phase rings of the objective using a centering telescope supplied with the microscope.

Plan semi-apochromatic phase objectives
Phase objectives have a phase ring in the exit pupil plane. They have a different level of aberration correction compared to the phase objectives included in the microscope kit.
Plan semi-apochromatic objectives correct chromatic aberrations for four colors, spherical aberration for three colors, and field curvature for 90% of the field of view diameter. The image in the eyepieces and through the digital camera is sharper, has higher contrast, and is brighter than with a conventional plan achromatic objective.
4х, 10х, 20x, and 40x objectives are used to be able to work with plates that have a 1.2 mm thick bottom.
The 60x objective has a correction ring. Rotating the ring changes the distance between the inner lenses of the objective, thereby adjusting the objective optics for working with plates with a bottom thickness from 0.1 mm to 1.3 mm.
The objectives are designed for the tube length with infinity correction. The parfocal distance is 60 mm.
