LOMO MULTISCOPE BMH4-BF binocular microscope Product Info

LOMO BMH4-BF MULTISCOPE binocular microscopes - The best value in the world of microscopy must be the general-purpose Multiscope™ line of modular microscopes! Sparkling RMS Achromat and Plan Achromat optics with a 33mm parfocal distance, an extensive array of included and optional accessories, and modest prices make the Multiscope™ BMH4-BF microscope an ideal choice when classic optical performance is required, but cost must be a consideration. Even at our low prices, every Multiscope BMH4-BF binocular microscope includes a Limited Lifetime Warranty.

Do not confuse the LOMO BMH4-BF microscope with the cheaply made, low cost optics so frequently seen in advertisements and retail stores. This is a ruggedly made microscope with serious imaging capabilities! Utilizing a precision mechanical stage, and a high resolution optical system consisting of 4x and 10x plan achromats, 40x and 100x flat field achromats and a focusable 1.25 N.A. abbe condenser, the BMH4-BF will astonish you with its image quality and ease of use. Ready to use "out-of-the box", the BMH4-BF binocular microscope is capable of performing urinalysis tests, protozoan hunts, mycological spore analysis, blood counts, clinical samples and more! The binocular head on all Multiscopes™ includes a field-flattening 1.5x internal lens system to boost the microscope magnification 50%! For example,with the standard 10x widefield eyepieces, using the 4x objective yields an image magnification of 60x (10X x 4X x 1.5X). Using the 10x objective with the 10x eyepieces yields a magnification of 150x. Using the 40x objective yields 600x magnification, and so on to the 100x oil immersion objective, which yields an image magnification of 1,500x. Such a magnification range requires an ultra-precise focusing system. The "FineWheel™" fine focus control is ergonomically placed in the base of the microscope to limit unnecessary hand movement, and is coupled to one of the smoothest, most precise focusing systems in the microscope industry.

The LOMO®BMH4-BF binocular microscopes also include a brilliant 12V/20W variable intensity illuminator with a centerable bulb, and a precision 12-leaf aperture iris diaphragm in the sub-stage condenser. A swing-out reduction lens on the condenser allows the correct illumination of the full field of view with all objectives ranging from 4x to 100x. The built-in lamp housing sharply and evenly illuminates the specimen, while the external, variable intensity power supply keeps any transformer heat away from the microscope. 

Should you wish to "turbo-charge" your illumination to aid in high magnification, phase contrast and/or darkfield observations, a modestly priced 6V/15W halogen Koehler illuminator may be purchased as an optional accessory.

The array of optional LOMO Multiscope binocular microscope accessories includes a trinocular head capable of attaching 35mm, video and digital camera adapters for photomicrography, an assortment of eyepiece reticles, contrast-enhancing and neutral density filters, phase contrast, darkfield and reflected light upgrades,special objectives - and much, much more! Just ask!

Sample Applications

  • Education: Biology, Botany, Cell Biology, Morphology, Mycology, Zoology  
  • Health/Public Health: Blood counts, Urinalysis (Veterinary, Physician), Plaque examination(Dentist), Fecal examination (Veterinary) 
  • Agriculture: Plant and soil examination, animal diseases, semen vitality 
  • Forensic: Trace evidence examination 
  • Water Quality: Coliform counts

If you plan to take pictures or video, you will need a trinocular version of this microscope. In some cases our adapters can fit into an eyepiece tube on the binocular head. However, we find this to be an inconvenience most of the time and highly recommend a trinocular head for photomicrography. The TMH4-BF-V,F or E is the trinocular version of the BMH4-BF (-V comes with a 1.0x C-mount adapter for video cameras and some digital cameras, -F comes with a 2.4X T-mount adapter designed for attaching 35mm cameras, and the -E comes with a telescoping DIN standard (23.2mm) eyepiece tube adapter for inserting our digital camera adapters or 3rd party adapters) As with any of the items offered in our store, we encourage you to e-mail us with any questions!
