The AE30/31 by Motic is a high-grade inverted microscope for routine microscopy with the ability to add upscale research functions, such as fluorescence and an externally mounted and halogen Koehler illumination.The AE30/31 incorporates the Color Corrected Infinity Optical System [CCIS®] to power system expansions and to produce, along with the CCIS® Plan Achromat inverted objectives, crisp, flat and high contrast images in field flatness up to F.N.22. These images can be viewed for hours upon hours in fatigue free manner thanks to the comfortable 45° observation angle and viewing height of 380mm [400mm – trinocular], which is the perfect height from the laboratory tabletop to the users’ eyepieces.Complementing the uniform illumination is the ELWD 0.30 N.A. condenser with its 72mm working distance for large sample and carriers, which can be adjusted and centered to provide the optimum amount of illumination for each sample.The AE31 also provides a stable inverted “Y” designed stand. The inverted “Y” provides the necessary stability and weight distribution to handle the attachment of Epi-fluorescence and other accessories. The stand features ergonomic enhancements such as low position focus mechanisms to alleviate wrist strain while adjusting the focus at 1mm minimum increments. The stage sits at a comfortable height of 207mm for rapid sample changes. An optional universal mechanical stage [tilted adjustment] is also available with a series of Petri dish holders.
