System Microscopes

BH2 Series System Microscope The BH2 Series of topquality microscopes facilitates the use of a wide range of microscopic techniques, depending on the choice of accessories. The Koehler-type illumination elicits the full performance of the LB Series objectives, yielding photomicrographs of the highest quality. This series of microscopes is suitable for a very wide range of applications, from routine laboratory work to educational and research investigations.

Wandlng -v The design of the entire system--microscope stands, observation tubes, stages, etc.-bears witness to creative and inventive thinking. One example may be seen in the design of the coarse stage adjustment, in which movement is limited in the upward direction in order to prevent contact between objective and specimen. The coarse and fine focusing knobs are of coaxial design, and the mini- mum increment on the fine adjustment knob represents a stage mwernent of just two microns. The coaxial stage control knobs are located close to the focusing knobs, low enough to permit operation witt~wt having to raise the arm off the arm rest. In addition, the BH2-TR30 trinocular observa- tion tube features constant tube length adjustment which allows camera focus

through the binocular tube in phatamicrb graphy, thereby adding significantly to ease of operation. Improved Illumlnatlng System All BH2 Series microscopes employ the widely accepted LB Series objectives and WHKl OX eyepieces (as standard equipment). providing F.N. 20 widefield observation. BH2 Series microscopes provide Koehler illumination to exploit the full benefits of the LB Series objectives. A wide choice of condensers provides uniform illumina:icm from ultra low to high magnifications. These microscopes incorporate precentered halogen lamps, aspherical collectors and fully enclosed light paths designed to keep out dirt and dust.

BHS System Microscope This top quality microscope features a long-life 12V, I# W halogen lamp which provides bright illumination for a wide range of applications. It is ideally suited for advanced research work and investigatians requiring high precision.

BHSF Mhwcqm Stand .The BHS-F stand is of a robust and stable design unaffected by vibration or shaking. Highly reliable, it is ideal for photomicro graphic purposes.

.The stand incorporates a h i g h p e r f o m transformer which is unaffected by fluctua- tions in the line vdtage and so always provides light of uniform brightness and mlor temperature.

.The ball bearing sextuple revohring nose piece accepts law to high magnification objectives with 45mm parfocal distance. This feature contributes significantly to greater efticiency in microscopy.

BHSLSH Halogen Lamp Housing The IN l W halogen lamp provides a bright light source suitable for many types of microscopy. The precentered lamp has an average life of around 2,000 hours, reducing slgnlflcantly the time lml with troublesome bulb change.

BHT System Microscope Employing the same revoking nosepieces, stages, observation tubes, etc., as the Model BHS, the Model BHT microscope uses a different type of illumination system and electrical components. A compact microscope, it offers excellent cost-performance.

BHFF Mkmscmp Stand *Smaller than the BHS model, with a different transformer arKl lighl source. Extremely functional.

*The dust proof illuminating system keeps the light path clean.

LB (Long Barrel) Objectives The LB (Long Barrel) Series ranges from inexpensive objectives to top quality and special-purpose objectives. Thls extensive selection enables the user to choose the ideal lens for the purpose intended.

In the design of LB objectives, OLYMPUS has drawn upon its extensive and renowned expertise In optical technology. The objectives offer the following features: 1 . High resolution 2. Superior contrast 3. Excellent field flatness 4. F.N. 20 widefield observation (with

WHKl OX eyepiece) 5. Ultra-!ow magnification objectives are

parfocal wtth high-magnification lenses.

S Plan Apodumat Objactlm These objectives are of the highest quality design. Chromatic aberration is thoroughly compensated, field flatness is superb and the high numerical aperture provides outstanding resolution.

S Plan Aohmmat ObJechs The S Plan objectives are the most popular high quality objectives in the LB series. Excellent optical correction across the entire lens surfaces makes them ideally suited for use in differential interference contrast microscopy and for super widefield observation. S Plan FL ObJacthres The ultra low magnifications (lX, 2X) of these objectives make them ideal far examinatkm of large specimen areas. They are fully parfocal with other LB cbjet i is . The SRanFL2X objective is suitable for super widefieid otservatlons. Note: The objectives prform bast with the BHPULC

ultra-low condenser.

D Plan Achromat O b J e d w With D Plan objectives, fleld flatness is guaranteed up to F.N. 20. Ideal for photo micrographic purpses, they are widely used in research, educational and routlne work. D mrolmt Objective8 These are the most economically priced objectives in the LB series. Resolution and flatness in the center portion of the field of view are excellent and they are particularly suitable for routine work, educational purposes or training. N o ~ O b ~ This type of abjective is ideal for examination of specimens with no cover glass, such as blood smears. 'A varlety 01 other types of objectim are available for dlffarent applicatOwts and requirements, including p h m t r a s t , reflected light flwrescmce, or polarked light microscopy.

Eyepieces and Condensers To complement the performance of our LB objectives, an extensive range of eyepieces and six types of condensers are available. To exploit the full performance of objectives with magnifications from IX to lOOX requires the choice of the proper condenser.

WHKlNK Eyepieces I h

LB Serbs Eyepieces Designed for use with LB Series objectives, WHK eyepieces are easy and comfortable to use and are of widefield W i n (F.N. 20 with the WHKlOX eyepiece). The high eye point makes them easy to use by persons who wear glasses and enables fatiguefree observation over long periods of time. Other eyepieces in the series include the WHK8X, WHK15X, NK5X and NK20X. NFK Serks Photo Eyapkcss These photo eyepieces are speclflcally designed for photomicrography. They are available in 2.5X, 3.3X, 5X and 6.7X magnifications.

condemm An extensive range of condensers is available, covering brightfield and darkfield observa- tions. The BH2-AAC is a top quality achromatic aplanatic brightfield condenser which permits full compensation for all aberrations. The swingat BH2-SC condenser is suitable for a wide range of magnifications. Several other condensers are available, including the general-purpose BH2CD and the BH2-ULC for ultra-low magnification.

Observation Tubes All BH2 series observation tubes have constant tube length adjustment. This feature automatically maintains the optimum observation conditions when interpupillary distance is varied, without requiring troublesome adjustments.

B H N W Sup.r Wkkfleld Attachment The BH2SW attachment presents the observ- er with a field of view about twice the size of that obtained with wdinarv obwrvatbn i tubes, and thus reduces to a minimum the need to move the specimen around. This I resutts in a sinnificant Increase in work 1 efficiency. Ths 3-step light path selector and constant tube length adjustment allow I camera focusing through the binocular section for photomicrography. Inclination: 30' to the horizontal Interpupillary distance: 56-75mm (with

I constant tube length adjustment) Maximum F.N.: 26.5

BHBB130 Binocular Obswatlon f ibe The BH2-6130 is designed exclusively for visual observation. Inclination: 30' to the horizontal lnterpupillary distance: 53-75mm (with constant tube length adjustment) Maximum F.N.: 21

BHSTR30 Mrmcular Observation Tube This tube increases the efficiency of photo graphic work since it perrnRs camera focusing through the bkocular section. The three-step llgM path selector allows photwnicrography and observation at the same time. Inclination: 30" to the horizontal lnterpupillary distance: 53-75mm (with constant tube length adjustment) Maximum F.N.: 21

BH2.m Wkal Photohrbe This tube presents the most economical way of conducting photomicrography. The bim cular observation tube must be removed in wder to attach the vertical phototube and so ohenration is not pssible at the same time as photomicrography.

Stages A selection of stages is available, including those suitable for differential interference contrast and fluorescence microscopy.
