Grayfield Optical Inc - High Resolution Optical Microscopes

Notes:

• Resolution values given for the Ergonom microscopes relate to the practical achievable resolution. The maximum theoretical (although not achievable) resolution is 10nm with the Olbrich Lens System.

• The standard methods of measuring magnification in microscopes becomes too inaccurate beyond 1500x. We therefore determine the precise magnification factor by imaging a calibrated test slide with nanometer scale and printing that image on 10x15cm paper. The enlargement factor in relation to the grid is then used to calculate the actual magnification factor. Every objective combination is tested so that we can provide exact magnification ratios. As there are no parallax errors with our systems, it is possible to measure distance in any direction.

• For each microscope, there are a wide range of dry objectives available to match your application, e.g. 2,5x, 4x, 10x, 20x, 40x, 60x, 80x, 100x with n.A. up to 0.95 - some with extended working distance (WD). As the costs of the individual objectives vary widely according to their specifications, general price quotes are not meaningful before your exact requirements have been determined.

• The new updated Ergonom 3000 series, has been optimized to make it an affordable alternative to those considering high quality conventional optical microscope systems, yet with an image quality, depth of field and color contrast that is considerably better and especially suitable for live blood and live cell analysis. For technical reasons, it is not feasible to provide an Ergonom 3000 microscope with both incident and tranmitted light in one unit (costs would be higher than two individual microscopes).
