Polymeric Systems Bring Clarity to Optical Applications 24 May

Masterbond

Understand optical transmission, refractive indices, temperature and humidity testing, as well as the role of these measurements in choosing an effective adhesive for optical applications.

Solving PCR Optical Filter Challenges for High Performance qPCR Instruments 17 Mar

Iridian Spectral Technologies

qPCR instrument-related challenges can be daunting; burdened by tough deadlines and fast rollouts, budgets that offer little wiggle room, and expectations for flawless functionality. A combination of Iridian’s wavelength selective excitation, emission, and dichroic filters serving each channel of a qPCR instrument provide high sensitivity to these systems while preserving the necessary signal-to-noise ratio delivering “More Signal, with Less Background”

A Better Way to Focus: Linear Motor Focusing Stage Provides Superior Alternative to Piezo Actuators 22 Mar

Dover Motion

This white paper addresses high performance Z axis focusing for automated microscopy, along with some recent innovations in this space. Historically, piezo driven actuators have been used for these applications, but a Piezo actuator has very distinct limitations. Direct drive linear motor stages provide many advantages when compared to piezo nanopositioners. This whitepaper discusses both approaches to Z focusing motion.

Interfacing the Vision Research S990 to the BitFlow Cyton-CXP frame grabber 04 Aug

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.

Modified SiC mirrors: low-loss solution from UV to Mid-IR. Galvo-scanning systems, laser material processing, sensing and other applications 16 Aug

Altechna

Every day, new applications for laser light emerge and current ones – from laser manufacturing and processing to LiDARs – are growing in both importance and market size. A considerable number of these applications use galvo scanning systems to control the laser beam and guide it to perform a specific task. Altechna now has a lowloss solution to do these tasks as efficiently as possible.

Sb to Mn Energy Transfer Revealed using Time-Resolved Emission Spectroscopy (TRES) 09 Mar

Edinburgh Instruments

Zero-dimensional (0D) metal halide hybrids are an emerging class of semiconducting materials for optoelectronic applications including light-emitting diodes, lasers and photovoltaics.

VPH Gratings: Flexibility in Design 28 Feb

Wasatch Photonics

Wasatch Photonics VPH gratings offer optical and instrument designers a tremendous amount of flexibility to optimize performance for a specific application. In this tech note, we’ll discuss the benefits of the various standard and patented grating design technologies at our disposal, and the general grating parameters we can control to meet your specific needs – for wavelengths spanning 300-2500 nm.

A new spectroradiometer drastically improves filter quality 06 Jan

Admesy

Admesy develops spectroradiometers, colorimeters and light meters. They are used in large volume 24/7 production testing as well in smaller volume niche system manufacturers. One example is the successful cooperation now started with Cutting Edge Coatings GmbH (CEC).

Continuous Versus Discrete Calibration Sources: Consideration for Use 05 Nov 2021

Optronic Laboratories

High efficiency and long performance, rapid power up, and compact size have made LED-based sources an attractive alternative for lamp-based calibration systems.

One laser, multi-color nanoscopy 02 Nov 2021

Hubner Photonics

In this white paper we present a new technique that makes use of a single laser to excite multiple fluorophores in the same spectral range (red/far-red) coupled to a spectral demixing strategy that allows diffraction limits to be overcome thereby permitting 3D multi-color nanoscopy with increased simplicity, speed, and reliability of output data.

Optimize the performance and cost of your automated optical imaging system 09 Sep 2021

Dover Motion

Optimize the performance and cost of your automated optical imaging system with 6 key equations for selecting an imaging sensor, objective lens, Z-focusing nano-positioning stage and XY sample positioning motion. Topics covered include: optimal imaging sensor size and resolution, objective lens magnification and numerical aperture, and XYZ motion resolution and stability requirements to enable crisp images. Also discussed is how diffraction affects image resolution, and how to calculate the depth of field for a given objective lens.
