Optics Designed for OEM Integration

In order to make our lenses easier to integrate into OEM assemblies, Edmund Optics® has improved a variety of our standard tolerances. These changes were specifically designed to facilitate "drop in" assemblies, eliminating the need for complicated assembly procedures including active alignment. The precision specification changes were made through process improvements at our world class spherical manufacturing facilities in Japan, Singapore, and the USA, where EO produces millions of lenses annually. The improved specifications implemented include:

Diameter Tolerance: All of our TECHSPEC® spherical lenses, regardless of size, are now held to a diameter tolerance of +0.000/-0.025mm. Maintaining the diameter to within 25µm ensures the lenses will seat and align accurately within a well-designed barrel assembly.

Centration: All of our TECHSPEC® singlet lenses with a focal length >10mm now feature a centration of <1 arcminute. This precision alignment of the optical axis ensures the lenses can be used in demanding imaging applications.

Surface Quality: All of our TECHSPEC® spherical lenses, regardless of size, are now held to a scratch-dig value of 40-20. This precision cosmetic specification ensures the lenses can be used in demanding laser-based applications.
