The Benefits of Modern CMOS Sensors in Industrial Line Scan Cameras
As sensor technology has improved in leaps and bounds, the old rule of thumb familiar to many line scan camera users has lost much of its punch. The idea that CCD = high image quality while CMOS = speed is only true anymore under very limited circumstances, since the preconception inaccurately reflects the current performance levels offered by...

Real-time Profiling for Focusing, M2, Divergence & Alignment
Beam intensity profiling is an essential tool in many aspects of photonics. The precise intensity distribution in a focused laser beam is critical in many applications: flow cytometry, laser printing, medical lasers, and cutting lasers are just a few examples. Intensity profile measurements can characterize and improve a product or process,...

Use of White Light Fluorescence LED in long-term Live Cell Imaging Applications
Lamps have long been used in microscopy facilities to conduct time-lapse imaging experiments. Light uniformity, stability and sample exposure are key in generating reliable data. In this study, we evaluate an LED system (X-CiteĀ® 120LED) for our high-content time-lapse experiments and show that LEDs provide a better solution for imaging live cells...

Reduction of Substrate Thermal Damage Using Pulsed UV LED Curing Systems
UV LED curing systems deliver narrow bandwidth, high intensity UV light for low heat, rapid curing of optically-activated materials. Although LED curing systems do not deliver unwanted IR or visible light, some UV-absorbing substrates may still experience heating damage. This white paper demonstrates a novel method to reduce heat damage in...

Imaging Cells in Flow
Fluorescence microscopy enables the study of cells with molecular specificity and subcellular resolution. Despite recent improvements in the brightness of fluorescent labels and in the sensitivity of image sensors, imaging is usually limited to stationary cells. Imaging fluorescence in moving cells is fundamentally challenging because the exposure...

Design of Long Working Distance Graded-index Fiber Lens With a Low NA for Fiber-Optic Probe in OCT Application
A fiber-optic probe for optical coherence tomography (OCT) applications typically includes a short section of graded index (GRIN) fiber fused onto a single-mode (SM) fiber. The GRIN fiber acts as a lens to focus the output of the SM fiber and to collect the reflected light from the sample. In this paper we will use the beam propagation method...
