Barrington, NJ. Edmund Optics has introduced TECHSPEC Ultra Compact Objective Assemblies. The company says these microscope assemblies are its smallest objective and offer nearly the shortest and most compact form factor for an objective in their class of working distance, magnification, and resolution. The objectives can be customized for different magnifications by adding various extension tubes. Numerical aperture (NA) and working distance may also be adjusted by changing the base optics in the objective.
RoHS compliant TECHSPEC Ultra Compact Objective Assemblies are available in four models with 2x magnification, with focal lengths of 8 mm or 10 mm. The base optics use two different numerical aperatures with working distances of 11.4 mm and 9.9 mm. Five different C-Mount extension tubes are offered for the 8-mm and 10-mm lenses, for a total of ten models, with magnifications of 2x, 4x, 5x, 10x, 15x, and 20x.
