The Brunel SP200-XP is a good specification trinocular polarising microscope that is particularly well constructed to a modern design that uses established technology. The microscope stand has a two tone finish base with low position coaxial coarse and fine focus controls that incorporate both tension adjustment and a variable focus stop safety system.
n x4, x10, x25, x40 and x63 strain free polarisation achromatic objectives of excellent quality. The four position objective turret has very precise indexing, and each objective can be adjusted laterally in order to centre it in the optical path.
n x10 widefield eyepieces with a cross hair, grid and cross hair micrometer variant. The SP-200-XP has full interocular adjustment and dioptric control on each eyetube.
n The circular stage is fully graduated and has a ball bearing race to ensure smooth and rapid rotation. The stage is tapped to take a mechanical specimen driver with mushroom controls to avoid objective contact.
n The fully adjustable condenser has a numerical aperture of 1.30 and has an integral iris diaphragm and flip top lens. The top element of the condenser has lateral adjusters that allow centring within the optical path. A fully rotating and graduated polarising filter is attached to the condenser base.
n The analyzer unit is compact and features a graduated analysing filter with push/pull lever that can be rotated through 90 degrees. The Bertrand lens is housed in a slide mount and has its own centring adjusters. The is a filter slot for a quartz wedge, gypsum wavelength and mica wavelength retardation plates that are supplied as standard.
n The SP200-XP has an effective 6v 20 watt rheostat controlled quartz halogen light source, that can be accessed through a small trap door in the base of the microscope for easy bulb change.
n This is a substantial professional level polarising microscope that weighs 7 Kilograms. Height 450mm and Footprint 250 x 220cms
