Interfacing the Vision Research S990 to the BitFlow Cyton-CXP frame grabber 07 Dec 2020

Bitflow

This document explains how to interface the Vision Research S990, a high speed camera running 4K x 2k at 1000 FPS, to the Cyton-CXP4.

Infrared sensing using nanocrystal toward on demand light matter coupling 06 May

New Imaging Technology

Nanocrystals are semiconductor nanoparticles whose optical properties can be tuned from UV up to THz. They are used as sources of green and red light for displays, and also show exhibit promises to design low-cost infrared detectors. Coupling subwavelength optical resonators to nanocrystals film enables to design photodiodes that absorb 80% of incident light from thin (<150 nm) nanocrystal film. It thus becomes possible to overcome the constraints linked to the short diffusion lengths which result from transport by hopping within arrays of nanocrystals enabling high photoresponse detector operating in the SWIR range.

The Solution to Coating DLC on Chalcogenides 29 Apr

EMF

Coating chalcogenides with DLC is notoriously challenging and requires specialized technical expertise to meet the high performance and durability demands of IR applications

5 Applications of Gratings 29 Apr

Wasatch Photonics

Diffraction gratings that operate in transmission can be used for many different applications, providing high efficiency, low stray light, and a range of dispersion options from 150-5000 lines/mm and operating at wavelengths 300-2500 nm. They also enable more compact, lens-based designs. Here, we review the top 5 most popular applications we see at Wasatch Photonics, and how our VPH transmission gratings excel at each.

The “New” Raman: Streamlined, Flexible and Powerful 11 May

Pro-lite

It has been over 90 years since C.V. Raman received the Nobel Prize in Physics for the discovery which bears his name. Since that time, successive improvements in measurement systems have enabled Raman spectroscopy to become a powerful and versatile analytical tool that is applied in a vast array of applications from material science to medical diagnostics.

Realistic Optical System Tolerancing: A Practical Example 28 Jan

Ruda-Cardinal

While lens design software can assist with tolerancing, complex and/or critical optical systems require expertise beyond the software’s basic functionality. We represent tolerancing of optical systems as close to reality as possible by utilizing the most advanced tolerancing tools both built into lens design software and of our own creation

Light engine operating lifetime Robustness, Reliability, Longevity in Maintenance-free lighting 11 Nov 2020

Estimates of the operational lifetimes of solid-state light sources ranging from 10,000–50,000 hours of light output are frequently cited in research and commercial publications. However these estimates are often derived from performance data for single light emitting diodes (LEDs) and are not necessarily representative of integrated light engines in typical working environments. This white paper provides operating lifetime estimates for Lumencor’s solid-state light engines based on analysis of service history data.

Single Crystal Orientation Laue System For Gallium Phosphate for High Precision Piezoelectric Sensors 06 Nov 2020

Latest article from Christian Roethel at Piezocryst to find out how the Photonic Science Laue system is used for precision crystal orientation for piezoelectric sensors. Christian Roethel, has a PhD in X-ray Diffraction from the Technical University of Graz. He joined PIEZOCRYST ADVANCED SENSORICS GMBH in 2018 as the head of sales and the product management team. Christian is involved in the products from conception through to sales and marketing and is the applications expert. Piezocryst, are part of the AVL group, who are focused on the development of combustion engines and more recently electric engines for the automotive industry.

CONCENTRIC MOUNT FOR OFF-AXIS PARABOLA ALIGNMENT 05 Nov 2020

OAPs have many advantages because they can focus without aberrations; but are notoriously difficult to align. We present a method and mount for accurate alignment to any coordinate system.

Room Temperature Terahertz Frequency Comb Using Quantum Cascade Lasers 22 Oct 2020

Wavelength Electronics’ QCL LAB Driver and PTC temperature controller provide the high-precision and ultra-low noise current and temperature stability needed for harmonic frequency combs.

Learn about a novel narrow-linewidth 785 nm laser and how it can be used in low-frequency Raman spectroscopy, especially for inspection of pharmaceutical products. 01 Oct 2020

Being able to access the low-frequency region in Raman spectroscopy promises better insight into the detailed composition of pharmaceutical drugs and also stronger Raman signal levels. In this white paper we introduce a stable narrow-linewidth laser source at 785 nm and discuss the performance required to address low frequency Raman spectroscopy needs.
