High Precision Lens Assembly with Alignment Turning MachinesIn recent years, alignment turning technology has experienced some key developments. Progress has been made with regard to aspheres, cylindrical surfaces or "best fit" centration of lens groups. It has also been possible to significantly increase...
Fabricating and Testing Freeform Optics: Current Capabilities, Lessons Learned and Future OpportunitiesFreeform optical shapes or optical surfaces that are designed with non-symmetric features are gaining popularity with lens designers and optical system integrators. A common question about freeform optics is, “If I design it, can you really make...
Ultra-Narrowband Optical Bandpass Filters with Large Format and Improved Temperature StabilityHard coated ultra-narrowband optical filters made using modern plasma processes offer much improved transmission, temperature stability and out of band blocking as compared to legacy soft coatings. These filters are used in optical systems as...
Spatial Light Interference MicroscopySpatial light interference microscopy (SLIM) is a highly sensitive quantitative phase imaging method, which is capable of unprecedented structure studies in biology and beyond. SLIM combines two classical ideas in optics and microscopy: Zernike's...
High Volume Optical Component Testing Using an Agilent Cary 7000 Universal Measurement Spectrophotometer (UMS) with Solids AutosamplerIn this study, we demonstrate increased productivity and reduced cost-per-analysis with automated, unattended multi-angle R/T analysis for multiple samples of uncoated fused silica using an Agilent Cary 7000 UMS fitted with an Agilent Solids...
Beam Expansion - Standard Concepts Re-interpretedEveryday work in an optics laboratory would be unthinkable without beam expansion systems. They serve to optimally adjust the beam cross sections between the light sources (e.g. lasers) and the subsequent optical elements. Precise illumination of...
Measuring Optical Densities Over 10 Abs on the Agilent Cary 7000 Universal Measurement Spectrophotometer (UMS)High blocking optical filters deliver critical optical control in a wide variety of consumer and industrial products. Highly attenuating (i.e., high optical density) filters are used in personal protective equipment, such as laser safety eyewear,...
Understanding Infinity-Corrected Objective Resolving Power and MagnificationThis informative white paper from Edmund Optics covers a range of topics from the field of Microscopy, including terminology, application examples, and descriptions of different types filters such as dichroic, emission, and excitation filters used...
Clearly Superior Epoxies for Optical ApplicationsAs technology in the optics industry continues to advance and improve, careful consideration of the properties of epoxies must be evaluated. When determining the most effective adhesive to be used in opto-electronics, medical and other optic related...
