best value in theworld of microscopy must be the general-purpose Multiscope™ line ofmodular microscopes! Sparkling RMS Achromat and Plan Achromat optics with a 33mmparfocal distance, an extensive array of included and optional accessories, andmodest prices make the Multiscope™ BRH4-POL an ideal choice whenclassic optical performance is required, but cost must be a consideration. Evenat our low prices, every Multiscope™ BRH4-POL microscope includes a LimitedLifetime Warranty.
Do not confuse the LOMO BRH4-POL microscope with the cheaply made, lowcost optics so frequently seen in advertisements and retail stores. This is aruggedly made microscope with serious imaging capabilities! Utilizing aprecision circular, rotating and centerable stage, a glass polarizer andanalyzer, and a high resolution optical system consisting of 4x and 10x planachromats, 40x and 100x flat field achromats and a focusable 1.25 N.A. abbecondenser, the BRH4-POL will astonish you with its image quality and easeof use. Ready to use "out-of-the box", the BRH4-POL is capableof looking at hairs and fibers, thin sections of minerals, explosives, glass,asbestos, biologicals and more!
The binocularhead on all Multiscopes™ includes a field-flattening 1.5x internal lenssystem to boost the microscope magnification 50%! For example, with the standard10x widefield eyepieces, using the 4x objective yields an image magnification of60x (10X x 4X x 1.5X). Using the 10x objective with the 10x eyepieces yields amagnification of 150x. Using the 40x objective yields 600x magnification, and soon to the 100x oil immersion objective, which yields an image magnification of1,500x. Such a magnification range requires an ultra-precise focusing system.The "FineWheel™" fine focus control is ergonomically placedin the base of the microscope to limit unnecessary hand movement, and is coupledto one of the smoothest, most precise focusing systems in the microscopeindustry.
The LOMO®BRH4-POL microscope also includes a brilliant 12V/20W variable intensityilluminator with a centerable bulb, and a precision 12-leaf aperture irisdiaphragm in the sub-stage condenser. A swing-out reduction lens on thecondenser allows the correct illumination of the full field of view with allobjectives ranging from 4x to 100x. The built-in lamp housing sharply and evenlyilluminates the specimen, while the external, variable intensity power supplykeeps any transformer heat away from the microscope.
Should you wish to "turbo-charge" your illumination to aid in highmagnification observations, or to ad brightness to your sample'sbirefringence, a modestly priced 6V/15W halogen Koehler illuminator may bepurchased as an optional accessory.
The array of optional Multiscope™ accessories includes a trinocularhead capable of attaching 35mm, video and digital camera adapters forphotomicrography, an assortment of eyepiece reticles, contrast-enhancing andneutral density filters, phase contrast, darkfield and reflected light upgrades,special objectives - and much, much more! Just ask!
Note: Unfortunately,the BRH4-POL microscope does not include or accept compensator(retardation) plates. It is strictly designed to be a qualitative polarizedlight microscope, and we apologize for the inconvenience. It is possible,however, to purchase small sheets of retardation film and insert them into thelight path by hand to simulate the effect of compensators. If you need apolarized light microscope capable of using and accepting compensators, thenplease ask us about the POLAM series of polarized light microscopes. Ifyou have any questions, please emailus.

Ifyou plan to take pictures or video, you will need a trinocular version of thismicroscope. In some cases our adapters can fit into an eyepiece tube on thebinocular head. However, we find this to be an inconvenience most of the timeand highly recommend a trinocular head for photomicrography. The TRH4-POL-V,F or E is the trinocularversion of the BRH4-POL (-V comes with a 1.0x C-mount adapter for videocameras and some digital cameras, -F comes with a 2.4X T-mount adapter designedfor attaching 35mm cameras, and the -E comes with a telescoping DIN standard(23.2mm) eyepiece tube adapter for inserting our digital camera adapters or 3rdparty adapters) As with any of the items offered in our store, we encourageyou to email us withany questions email@example.com!
