INVERTOSCOPE™ Inverted Microscopes

LOMO has designed the INVERTOSCOPE™ Series to be the most durable and easy-to-use microscopes for tissue culture work and other applications requiring inverted design and long working distance optics.

The versatile and efficient INVERTOSCOPE™ combines the highest optical performance with unsurpassed mechanical quality, and is backed by LOMO's unique lifetime warranty, the most comprehensive in the industry. INVERTOSCOPE™ Microscopes come loaded with valuable extras that would cost hundreds of dollars more from any other manufacturer because we believe that you are entitled to start using your microscope right from the box.

Besides standard objectives, eyepieces and sliders, every INVERTOSCOPE™ model always comes with:

  • A 15X focusing eyepiece with two interchangeable reticles (a 10mm/100div scale and a 10mm x 10mm/400sq grid) for convenient measuring and counting.
  • A set of six high-quality filters to enhance your image.
  • A filter set for Polarization (Polarizer and Analyzer).
  • A centering telescope to help you align the phase annulus rings.
  • A replacement bulb for uninterrupted operation.
  • A set of stage inserts and extension plates to accommodate a variety of sample vessels such as Petri dishes, flasks, microtest plates, etc.


The INVERTOSCOPE™ provides you with a choice of two easily interchangeable high-performance observation heads, both 360 rotatable for comfortable viewing. LOMO's exclusive multilayer coating technology ensures bright, flare-free images.


The large, sturdy 250mm x 265mm base, with four rubber feet, provides maximum stability and insulates the INVERTOSCOPE™ from vibrations, a particular advantage for photomicrography.


Smooth coaxial focusing is achieved by the INVERTOSCOPE's wear-resistant roller-race mechanism that virtually eliminates backlash and unwanted lateral shift of the specimen. One full revolution of the large knurled knobs corresponds to 6.5mm (coarse) and 0.250mm (fine) of the stages vertical movement. The coarse focus has a travel range of 19mm. The graduated micrometer knob allows vertical measurements accurate to 0.002 mm.


The INVERTOSCOPE's quadruple revolving nosepiece and has a wide knurled grip for easy rotation and features a precision ball-bearing mechanism with click stops for parfocality, parcentricity and exact optical alignment.

STAGE (Attachable Mechanical)

Convenient, fatigue-free operation is assured by low-position X and Y controls with knurled knobs. The precise, wear-resistant mechanism allows smooth specimen cross-travel (120mm x 70mm) measured against two 1 mm-graduated scales with verniers accurate to 0.1mm. Can be installed at either right- or left-hand control positions. The mechanical stage can accommodate a 96-well microtest plate holder.

Set of Stage Inserts and Extension Plates
Accommodate a variety of vessels, such as Petri dishes, flasks, bottles, microtest and microtiter plates, etc. The plain stage is 170mm x 180mm and can be extended to 300mm x 180mm to accommodate extra-long flasks and bottles.


The Illuminator incorporates a high-performance long-working-distance condenser with two operating positions: lower (W.D. 44mm) for observation of specimens in culture vessels, microtest and microtiter plates, etc., and upper (W.D. 110mm) for working with high-profile flasks. The aperture iris diaphragm and the slots for sliders, filters and polarizer are built- in. The 12V/50W halogen lamp ensures sharp, bright images for all magnifications and contrast techniques, and perfect color temperature control via an external transformer for photomicrography. The heat-absorbing filter protects your delicate tissue culture specimens from heat-induced damage.


The INVERTOSCOPE™ features an array of TQA-Series Plan Achromats.
