Design, Fabrication, and Testing of Aspheric surfaces Introduction Aspheric lenses have become synonymous with high-performance optics. They are used in an optical design to correct aperture dependent aberrations (spherical aberration), to correct field dependent aberrations (distortion and field curvature), to reduce weight, to make optical systems more compact, and in some cases to reduce cost.

Electro-Optical Environmental Considerations

Electro-Optical Environmental Considerations Introduction In the requirement development, design, and system development the majority of attention is paid to the mechanical, electrical and optical components and assemblies of Electro-Optical systems. In many cases the intended operating environment is overlooked or the requirement implication misunderstood. This paper will look at a few of the more common […]

Birefringence Precision Measurement and Reduction Tutorial

Birefringence Precision Measurement and Reduction Tutorial High precision optical instruments used in industrial applications require control of many variables in order to maintain precise measurements. All of the optical components in a precision system must be controlled. One of the most important parameters to control in many applications is residual linear birefringence due to a […]
