Axiophot Training Policy

axiophot blue2

 

Light microscope equipped for bright field (both transmitted and reflected), phase contrast, transmitted and reflected polarization and Nomarski differential interference contrast microscopy, as well as epifluorescence. Examples of imaging modes are shown below. Motorized focus via the Prior Optiscan system allows acquisition of stacks of optical sections and subsequent deconvolution. The microscope is equipped with color and monochrome CCD cameras. Image acquisition is controlled via the MetaView software and also by the free Micro-Manager software (http://www.micro-manager.org). 

Optics:
2.5x, 5x, 10x, 20x, and 40x dry objectives
63x/1.40 and 100x/1.3 oil immersion objectives

Fluorescence filter sets: includes the set for GFP with a bandpass emission filter that is very effective in suppressing the background autofluorescence.

Examples of the imaging modes:

Example 1: Live cells of the filamentous fungus Neurospora crassa, expressing Green Fluorescen Protein (GFP) fused to Histone H1. The GFP fusion protein is localized in the nucleus.

 

 Example 2: Cross-section of a wooded plant stem.
