Absorption / Transmission / Reflection Spectroscopy
Ultraviolet Visible Near-Infrared (UV-Vis-NIR) spectroscopy is useful to characterize the absorption, transmission, and reflectivity of a variety of technologically important materials, such as pigments, coatings, windows, and filters. This more qualitative application usually requires recording at least a portion of the spectrum for...

Narrow Line Diode Stacks for DPAL
Diode pumped alkali metal vapor lasers (DPALs) offer the promise of scalability to very high average power levels while maintaining excellent beam quality, making them an attractive candidate for future defense applications. A variety of gain media are used and each requires a different pump wavelength: near 852nm for cesium, 780nm for rubidium,...

Next Generation Thin-Film Optical Filters for Life
Fluorescence based systems have revolutionized the way organisms, cells, and biomolecules are visualized and detected. However, challenges that are common in these instruments, such as bleedthrough, background autofluorescence, and poor signal-to-noise ratios (S/N), can reduce performance and lead to frustration. Fortunately, performance and...

CMOS Image Sensors are Entering a New Age
In the early 90’s, it was suggested that Charge Coupled Devices (CCDs) were in the process of becoming extinct and considered to be ‘technological dinosaurs'. The prediction is not entirely wrong, if the announcement made by Sony in 2015 is taken as an example. Sony Corporation has officially announced the end of the mass production of CCD and has...

High Performance SWIR Imaging Cameras
Silicon based area detectors (e.g. CCDs or CMOS) are widely used in high performance imaging applications, detecting wavelengths from soft x-ray through to near infrared (NIR). Typically the quantum efficiency (QE) of these detectors decreases rapidly as the detection wavelength increases further into the NIR region. The use of imaging systems to...

Discover the Truth About Range Data
Security Systems Integrators know that effective site design comes down the level of fidelity in the camera range performance data. The industry is flooded with conflicting information when it comes to range performance. Accurately gauging range performance from the onset of the site design may allow one to avoid unintended, and pricey rework...

Optimax-OTR Coatings for Extreme Environmental Resistance
Optimax has developed a novel optical coating (OTR-AR) that protects optical surfaces in even the most extreme environmental use conditions. OTR coatings have been demonstrated to provide excellent resistance to latent scratching, staining and dimming of chemically sensitive optical glass surfaces in hot-humid environments.

Selecting the Optimal Er/Yb Doped Optical Fiber: Design Considerations and System Performances
Er/Yb fibers are well suited to achieve high performances in the 1.55 µm wavelength range, allowing to reach a few Watts to Watt-level of output power. However, we demonstrated that these performances are directly tailored by the core composition and the structural design of the fiber. The key to success is to clearly identify the target output...

Are Off-the-Shelf Optics Always the Best Solution?
A white paper from Resolve Optics addresses the commonly asked question "Are off-the-shelf optics always the best solution?". Today there exists a huge number of off-the-shelf lenses for mass market applications where unit cost is the dominant driving force. However when it comes to an application that optically requires anything a little more...

Fluorescence Lifetime Imaging Application Simplified... With the pco.flim
The pco.flim whitepaper gives an introduction in fluorescence lifetime imaging, if it is done in the frequency domain, with all the required background information. It is thought to refresh the knowledge about photo luminescence and how lifetime imaging is done in time domain and frequency domain. Further it describes the characteristics of the...

High Precision Lens Assembly with Alignment Turning Machines
In 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 the accuracy that can be achieved, in particular because the machines and control technology used have...

LIDAR Guns, Accuracy, and Speeding
Anyone who has driven a vehicle has encountered a Light Detection and Ranging (LIDAR) system in action. But how do you know if the detector is working? Let’s take a look behind the scenes at the beam, its scattered light, and the telescope that is used to collect data on the scattered light. The system then calculates the distance to the target...
