Optics, Sensors & Detectors White Papers
Thin Substrate, Dichroic and Polychroic Thin Film Filters Featuring Flatness <0.1 Waves RMS
The filters used by fluorescence detection systems are arguably the most important element defining the system performance. Alluxa’s new line of thin substrate ultra-flat dichroics and polychroic filters provide improved optical performance, achieve...
Advanced Light Cure Adhesive
Breakthroughs in adhesive technology enable light curing adhesives to cure under a visible light wavelength of 405 nanometers. Learn how these environmentally friendly adhesives can improve worker safety and lower production costs while offering a...
Durable, Front Surface Hard Optical Coatings for Replacing Laminated Soft Coatings
Soft coatings possess poor environmental durability, poor temperature stability and low transmission, high optical scatter, yet they are still used mostly due to low cost. Alluxa’s advanced high speed deposition technology has finally enabled hard...
New Metrology Techniques for Advanced Thin-Film Optical Filters
The performance of advanced thin films as demonstrated by Alluxa’s thin films are challenging even the best metrology equipment and techniques. In this paper we have described a number of simple techniques, such as reference beam attenuation,...
UV Curing Adhesives Shine
UV curable adhesives are among the most user friendly adhesive products on the market today—if you know how to apply them. Master Bond’s new white paper takes a closer look at the capabilities of UV curable formulations, the requirements for an...
Super-resolution Microscopy
This article provides an overview of some of the key developments in super-resolution microscopy -- the art of enhancing the diffraction-limited resolution of an optical microscope.
Asphere Metrology: Options for Measuring Aspheric Lenses
This paper will outline the numerous metrology options for aspheres at Optimax, including how they work, any requirements, and what is specified with each method in an effort to help reasonably tolerance aspheres. Effects on the fabrication and cost...
Assembly Method Considerations for Cemented Assemblies
This paper will examine options in assembly methods of cemented lens assemblies, and techniques for communicating critical items will be presented. When cementing lenses together at Optimax, there are two main options for assembly methods, V-Block...
Considerations in Manufacturing Cemented Assemblies
This paper will examine options in construction of cemented lens assemblies, and considerations for mechanical mounting and cement selection will be offered.
An Introduction to FRET, with an Emphasis on the Optics Involved
Fluorescent Resonant Energy Transfer (FRET) is a process that involves two fluorochromes (molecules that have the potential to fluoresce) with overlapping emission and excitation spectra. FRET is useful in determining intra-molecular and...
Filter Sets for Imaging DsRed (Red Fluorescent Protein)
The new red fluorescent protein, DsRed, from Clontech can be viewed, and imaged, with a variety of filter sets due to its broad absorption and emission spectra. Using HeLa cells transfected with the DsRed protein, kindly provided by Clontech, we...
How to measure optical filter spectra accurately
Optical filters play an important role in enabling applications such as fluorescence microscopy and Raman spectroscopy. In these applications there are two distinct types of beams: the illumination (or excitation) beam and the signal (or emission)...
