Spotlight On Optical Coatings & Filters
Understanding Edge Filters For Raman Spectroscopy

Since the excitation source laser intensity is often six to eight orders of magnitude greater than the Raman scattered signal, edge pass filters are required to block the wavelength of the scattered laser beam while transmitting the wavelength shifted Raman scattered signal.

Fiber-Q Fiber-Coupled Acousto-Optic Modulator

An acousto-optic modulator manipulates light through a transmission medium. The Fiber-Q component line contains offerings from visible through to 2 µm and is fully customizable to meet application requirements with connectors, high power capability, optical fiber pigtails, and more.

Flat Top, Ultra-Narrow Bandpass Optical Filters Using Plasma Deposited Hard Oxide Coatings

Alluxa’s new class of ultra-narrow filters are designed for applications such as laser cleanup, lidar, telecommunications, and instrumentation, and offer the narrowest and “squarest” filter profiles in the visible and NIR as well as transmission levels that approach 100%.

Optical Thin Film Coatings Provide Safer Flight Conditions

Specialized thin film optical coatings are currently being designed into customized displays that serve to modify the viewing angle and eliminate unwanted stray light that would otherwise distract the pilot(s) and crew in commercial and military aircraft cockpits. 

Optical Filters For 1550 nm Light Sources In Sensing Applications

The 1550 nm band can supplement or replace the 905 nm band in automotive lidar applications. HOYA offers superior filtration options for designers operating in both bands. 

Industry Insights
Cytometry Gets Fast

Flow cytometry plays an increasingly important role in cell analysis. Modern flow cytometry, which can support cancer research and drug development, has analyzers that allow researchers to characterize the image of single cells. This characterization provides insights into a variety of key cellular phenotypes.

How To Easily Speed Up End-Of-Line Quality Testing For Lasers

Reliability and safety demands are placing high levels of responsibility on manufacturers of laser systems. To ensure the high quality of each laser system, thorough end-of-line testing is mandatory before a laser system is delivered. 

Driver Vision Enhancement (DVE) With SWIR Cameras

There are many current DVE systems that use passive thermal imaging systems to enhance a driver’s viewing capabilities while operating in darkness, fog, smoke, dust, etc. SWIR has emerged as a leading technology that meets the needs of DVE. 

Neutron Hardness Of Photodiodes For Use In Passive Rubidium Frequency Standards

With the goal of obtaining a photodiode that's more neutron-resistant than what's typically used in an RFS, experiments in this case study evaluated several different types of planar silicon photodiodes.

Lens Specs Matter, So Do Your Homework!

Engineers are a special breed known for their love of precision and efficiency. So why is there a growing number of emails and phone calls inquiring about lenses without any forethought given to the lens specifications, performance requirements, and system and design context?
