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.

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”

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 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.

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.

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.

LISUN GROUP launched Integrating sphere and Flicker system to meet new ErP EU2019/2020 standard 09 Aug 2021

LISUN Group

At present, ErP has issued new regulations (ErP Regulations (EU) 2019/2020 for Lighting Products and Energy Efficiency Labelling Regulations (EU) 2019/2015) on 5th December, 2019. The new regulations have come into effect on 25th December, 2019. That is, from 25th December, 2019, you can apply for the ErP of the new regulations. The new regulations will be enforced on 1st September, 2021. It means from 1st September, 2021, all products must be applied for in accordance with the new regulations. , The old regulations EC 244/2009, EC 245/2009, EU 1194/2012 and the energy efficiency label regulation EU 874/2012 are simultaneously invalidated.
