Overview

The Em1 is an incredibly compact, rugged, lightweight, and powerful portable microscope, offering up to x1000 magnification with fully integrated LED lighting.

High-resolution digital images can be captured using any smartphone and camera accessories.

Due to its revolutionary design, engineering and portability, the Em1 microscope can be used for a wide variety of tasks. Its ease-of-use, compact form, and simple setup create a new and exciting benchmark in the world of microscopy.

Origin

The Em Microscope concept evolved from a challenging set of design criteria: to create a robust, portable, affordable microscope capable of diagnosing tropical diseases at the health periphery. The resulting product, the Em1 is has convincingly achieved those original objectives. But it is also very suitable for a range of other applications such as healthcare, field science, general microscopy, veterinary pathology, micro-photography, and academic research.

Despite the emergence of other field microscope designs over the last half century, no other instrument has fully satisfied these stringent requirements – the provision of a portable microscope with fully integrated lighting, XY indexing and high quality optics capable of diagnosing the blood-borne protists including malaria. The World Health Organization recently reaffirmed its conviction that microscopy remains the ‘gold standard’ for the diagnosis of malaria despite the availability of RDTs (Rapid Diagnosis Tests). The microscope, in capable hands, is able to diagnose a wide range of tropical diseases at far less cost per patient and may also make a significant contribution towards the mapping of disease prevalence to better guide vaccine and drug delivery programs.

The Em1's development program included laboratory equivalence testing and practical field trials in tropical locations for the diagnosis of malaria and the NTDs (Neglected Tropical Diseases). Innovative design, simplification and the application of state-of-the-art manufacturing processes and materials have made the Em1 a reality.

Features

Ultra compact - At a weight of just 480g and a form factor of 154 x 122 x 64 mm, the Em1 is an unprecedented addition to the world of microscopes and can be carried anywhere with ease, yet will match the performance of the conventional laboratory-bound instrument.

Illumination - Fully integrated Illumination is provided by a white daylight-balanced miniature LED located in an adjustable lighting arm which can be moved to provide various lighting effects including darkground. The Em1 requires three AAA batteries which are extremely compact and widely available globally.

Focus - Focus is achieved with a rotating knob on the edge of the Em1. A continuous cam-action is employed and this novel feature ensures that focus is always achieved within a single revolution of the focus wheel no matter which way it is turned.

Fine Focus - A larger clip-on focus wheel is provided as standard to provide very precise focus especially at higher magnifications.

Slide Indexer - A micrometer XY indexer is provided as standard to allow very precise movement of specimen slides for scans and cell counts etc. It may easily be removed (two screws) and the provided slide clips may be substituted if desired.

Precision Optics - Special highly miniaturized objectives were developed for the Em1 microscope and are constructed from high quality precision ground Schott glass.

Magnification - The objectives are mounted on a carousel. Up to three may be provided depending on the model, with magnifications of x100, x400, x600 and x1000 (oil).

Brightness - This may be varied with the use of the thumbwheel and guided by the graphics. Higher microscope magnifications require more illumination and vice versa. Illumination levels may also be varied by lifting the lighting arm slightly.

1,000 hours - Extremely efficient LED circuitry delivers superb battery life. At high magnifications, which require brighter illumination, the internal battery pack should provide approximately 300 hours of use. At low magnifications the battery life will improve to approximately 1,000 hours.

External Power - The internal circuitry of the Em1 also permits illumination to be provided by an external USB connecter (supplied).

Mountings - The Em1 microscope may be attached to a small photo table tripod to convert it to a bench microscope. Two standard photographic tripod bushes (1/4" UNC) are provided on the underside of the Em1.

Optical System

The optical system is based on the standard RMS 160mm “tube” length and can accommodate an interchangeable range of standard RMS eyepieces. The compact hand-held form has an inverted design with the optical path folded three dimensionally using one Z-axis mirror and two XY-axis mirrors. The objective lenses have been specifically miniaturized for the microscope in order to reduce size and weight.

The aluminum optical chassis assembly is decoupled from the external molded casing, providing a high level of protection from physical shock.

The optical system is illuminated by a white-light balanced miniature LED. The tube mounting collimates the light source providing a narrow beam. Illumination/contrast levels can be adjusted by moving the light arm angle. The PCB design provides variable brightness control with power options from internal batteries or the external mini USB connection.
