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...
System Integration of Fiber Lasers and Its Effects on Laser Quality
The quality of a laser is usually only measured on the laser source. But most laser sources are integrated into a system being used for a specific process or application. This means the laser light can interact with different components, each of which can have an effect on its quality. This paper looks at specific examples of beam profiles and...
Line Scan Cameras Enable High Speed Inspection of Color Filters Within Flat-Panel Display
The market of flat-panel displays (FPD) is a nearly $100 billion business that needs efficient automated optical inspection (AOI) to meet rising demand and remain cost effective. The color filters within the display represent a major inspection task, demanding both precision and speed. Inspection systems using high-speed, high-resolution line scan...

Sensor Resolution Versus Lens Resolution
An informative new white paper from Resolve Optics addresses the often misunderstood considerations when selecting an optimum lens for your digital camera or sensor. The ability of a lens to resolve detail is usually determined by the quality of the lens but is ultimately limited by diffraction. It is commonly thought that the resolution of a lens...
Apples to Apples: Which Camera Technologies are Best for Beam Profiling
An in-depth look at the evolution of commercial camera technologies and their use in measuring laser beams. The accuracy of beam width measurements varies depending on signal-to-noise ratios and baseline correction. In Part 1, we cover modern camera technologies, including CCD cameras and CMOS imagers. In Part 2, we discuss baseline correction...

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...
How can I find the right digital camera for my microscopy application?
Nowadays, image processing is found in a wide range of optical microscopy applications. Examples for this are medical and biological research, diagnostics, testing of medicinal products, or material sciences. Microscopy cameras are an important component of these systems and the specific requirements of your application will drive the selection of...

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...
Toward a single-chip TECless and NUCless InGaAs SWIR camera with 120dB Intrinsic Operation Dynamic Range
This paper describes NIT’s single-chip InGaAs SWIR camera with more than 120dB instant operational dynamic range with an innovative CMOS ROIC technology, so called MAGIC where the pixel is driven in a solar cell mode, invented and patented by New Imaging Technologies. A 640x512-pixel InGaAs 15µm pitch photodiode array, designed by NIT, has been...
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...
