The POLAM™-L Transmitted Polarized Light Configuration of the POLAM™ family (For the Reflected Polarized Light Configuration – POLAM™-P click here) is capable of both Orthoscopic and Conoscopic studies of transparent birefringent specimens, offers the advantages of all major contrast techniques – Brightfield, Darkfield, Phase Contrast, and Dispersion Staining (Central and Annular) – and is perfectly suited for photomicrography. The POLAM™-L always delivers sharp, crisp images, setting new performance standards in transmitted polarized light microscopy

POLAM™-L Microscopes come with everything you need to start performing your task, right from the box. They are loaded with valuable extras that would cost hundreds of dollars more from any other manufacturer: set of contrast-enhancing filters, set of graticules for measuring, counting and photomicrography, daylight mirror, centering wrenches, etc.

OBSERVATION HEAD

The POLAM™-L comes standard with the HU-POL Universal Head. The 360° rotatable head features a built-in iris diaphragm, optical path selector and a vertical photo/video port. LOMO’s exclusive multilayer coating technology ensures bright, flare-free images.

Inclined at 20° for your comfort, the HU-POL Universal Head allows the adjustment of the interpupilary distance from 55mm to 74mm and has a ±5 diopter adjustment on each eyepiece tube. The right tube features two notches for orientation (90°/180° or 45°/45°) of the cross-haired eyepiece in relation to the vibration plane of polarized light. The Optical Path Selector (OPS) controls the position of a beam-splitter, allowing a fast and easy switch between observation and photomicrography/CCTV. LOMO’s exclusive multilayer coating on the prisms and the beam-splitter ensures high light transmission for bright, flare-free images.

BASE / STAND

The large, sturdy 200mm x 250mm tripod base with rubber feet provides maximum stability and insulates the POLAM™ from vibrations – a particular advantage for photomicrography. The base’s ergonomic design features armrests that are raised to allow easy access to all controls while the microscopist’s arms rest comfortably during the entire operation.

Rugged and stable, the “backbone” of POLAM™ Microscopes, the stand allows attachment of all the standard and optional modules and components such as stages, condensers, illuminators, intermediate module, and LOMO’s unique, rotatable Monochrometer.

FOCUSING

Smooth coaxial focusing is achieved by the POLAM’s wear-resistant ball-bearing mechanism that virtually eliminates backlash and unwanted lateral shift of the specimen during focusing. One full revolution of the large knurled knobs corresponds to 6.3mm (coarse) and 0.25mm (fine) of the stage’s vertical movement. The coarse focus has a travel range of 33mm and the fine – 2.5mm. The graduated micrometer knob allows vertical measurements accurate to 0.002 mm.

CONDENSERS

Two high-performance, achromatic, strain-free condensers are available with POLAM™-L microscopes. Each includes a polarizer and comes with its own mount, thus making them easily interchangeable. Both feature a built-in aperture iris diaphragm and work effectively with the included swing-out element to provide even illumination for all objectives from 2.5x to 100x.

 

• CN-UPOL Universal Condenser

Each POLAM-L standard model is equipped with this state-of-the-art device to which it actually owes its unique versatility. The condenser includes one simple and effective feature unavailable from any other manufacturer in the world: a built-in, rotatable and centerable disc with six diaphragms for Brightfield, Phase Contrast, Darkfield and Dispersion Staining (central and annular). The top element is removable for work with lower magnification objectives.
The Polarizer PO-POL is mounted under the condenser.

INTERMEDIATE MODULE

With this module (IM-POL) as a standard feature on every POLAM™-L, the introduction into the optical path and rotation of the analyzer, manipulation of compensators, and the changeover between Conoscopic and Orthoscopic observation methods are quick and easy.

COMPENSATORS

Four different compensators are included with each POLAM™-L model, enhancing image contrast and allowing retardation measurements of of crystals, fibers, living organisms, etc. All sliders are DIN standard (6mm x 20mm) and fit into a slot in the Intermediate Module.

LOMO’s unique and patented Monochrometer is ideal for determining refractive indices of liquid and other specimens. It features a rotatable disc with six calibrated interference filters (comes with its own Certificate of Calibration). Tilting the disc at different angles will produce monochromatic light of wavelengths between 400nm and 700nm.
