  • TechSpec Compact Objective Assemblies
Apr 2014
Edmund Optics Inc.Request Info
BARRINGTON, N.J., April 18, 2014 — Edmund Optics has introduced its line of TechSpec Compact Objective Assemblies, devices designed to reduce the weight and size of an imaging system while maintaining optical performance.

Optimized to allow shorter tube lengths and long working distances, the assemblies are compact, light and offer configurable magnification.

Each lens includes broadband antireflective coating to provide even, maximized light transmission in the visible spectrum.

TechSpec assemblies are suited for application in the biomedical and machine vision industries, including microscopy, flow cytometry and inspection for pharmaceuticals, assembly lines and faults. The devices are available in 2×, 5× and 10× objectives with various numerical aperture options.

Indicating a capability to deal with a relatively wide spectral bandwidth.
flow cytometry
A method of measuring the characteristics of microscopic particles, usually cells, as they flow in a fluid stream through a beam of light. Particles may be stained with fluorescent dye and the fluorescence detected via laser illumination.
The ratio of the size of the image of an object to that of the object. The ratio of the linear size of the image to that of the object is lateral magnification. Angular magnification is the ratio of the apparent angular size of the image observed through an optical device to that of the object viewed by the unaided eye. Longitudinal magnification is the ratio of the longitudinal or axial dimension of an image to the corresponding dimension of the object.
See optical spectrum; visible spectrum.
A combination of components arranged so as to perform at least one function.
working distance
In microscopy, the clear distance between the specimen being viewed and the first optical element of the objective lens.
