Microscope BMS D1-223 Polarisation PLAN
This trinocular microscope is specially designed for research in the field of geology, petrography, mineralogy and medical science.
Trinocular microscope with high resolution plan objectives and two wide field eyepieces with plan optics. The high standard optics provide a clear, sharp, colourful and rich in contrast image. The firm and solid construction of the stand guarantee the stability of the microscope.
The integrated stage can be easily rotated and can be positioned in an easy and accurate way. The rotatable polarizer is attached to the in height adustable Abbe condenser (NA 1.25). All optical surfaces of eyepieces and objectives have been treated an anti-fungus coating.
The lamp house has a Köhler illumination, with iris diaphragm, and carries the halogen illumination.
Technical specifications
- Eyepieces: WFP 10x/18 mm with foldable eye guards, anti-fungus coating.
- Tubus: 45º inclined, 160 mm mechanical tube length, with grub screw to lock in the eyepiece.
- Head: trinocular, 360º rotatable, with lock bolt and milled edged screw. IPD 50 - 72 mm. Built-in Betrand lens with focussing knob. Bertrand lens and analyzer can be removed.
- Analyzer: pull out mechanism with graduation, mounted in head
- Nosepiece: quadruple, ball bearing type
- Objectives: DIN Plan POL achromatic High Resolution, 4x (N.A. 0.10), 10x (N.A. 0.25), 40x (N.A. 0.65) spring loaded (for slide protection). Objectives can be centered.
- Focussing: coaxial coarse and fine adjustment on both sides. Fine adjustment is supplied with a scale division. Each division equals 0.0015 mm (0.30 mm/rotation).
