What Is the Modulation Transfer Function?
The modulation transfer function, or MTF, is a parameter used to evaluate the performance of a lens. MTF provides a quantitative and standardized way to characterize optical systems, so the metric is used by optical designers and microscopists alike to compare lenses and determine the ideal one for an imaging system. Optical MTF data is used during the design of a range of instruments, including DNA sequencers, cell analyzers, slide scanners, and industrial inspection equipment. To help assist...
Telops New HD and Super HD Infrared Cameras
HIGH-DEFINITION THERMAL INFRARED CAMERAS WITH UP TO 3 MEGAPIXELS. The HD and Super HD Series are high-performance thermal infrared cameras designed to provide unprecedented image quality with crisp imaging of sharp targets while maintaining an...
Spectrometer Optics and Spectrometer Design
Spectrometer optics is the process of measuring light intensity by separating light by wavelength using a spectrometer. Spectrometers have a wide range of applications, from studying distant galaxies to detecting cancer. A basic spectrometer design...
“Fingerprint” vs Handheld Raman Applications and the Different Optical Filters That Enable Them
Raman spectroscopy is a powerful non-invasive, non-contact tool capable of identifying molecular constituents of samples. Wavelength selective optical filters are used to block the dominant Rayleigh scattered light and transmit only the Raman...
ATR-FTIR of Blood Serum Using a Heated ATR Accessory
This application note demonstrates the use of ATR-FTIR spectroscopy for the analysis of human serum albumin. An IR5 FTIR spectrometer was used, equipped with a heated ATR accessory, to help tackle the issue of strong water absorption bands masking...
Classification and Application of Endoscope
Endoscopic classification in terms of application, can be divided into two simple categories, namely, industrial endoscope and medical endoscope. About the types of industrial endoscope, from the imaging form can be divided into: optical endoscope,...
Embedded Motion Speeds Development of Next-Gen Sequencing Instruments
Small, precise motion modules enhance NGS system design and performance. Following the Human Genome Project, companies are racing to develop Next-Gen Sequencing (NGS) instruments for DNA sequencing. The newest techniques focus on increasing...

Advantages of VPH Gratings
The term 'diffraction grating' often brings to mind a surface relief grating, with ruled lines and a delicate surface. A transmission grating, however, opens up many new options for the optical designer. In this tech note, we consider one special...
Ingenuity + Instrumentation: Creating a Novel 4D Microscopy Method
Tracking particles at the micro or nanoscale is inherently difficult due to the complexity of the systems studied, as well as the technical challenges: a blend of instrument design, photonics, modeling, and imaging. The Welsher Lab at Duke...
Precision Motion and How to Achieve It
Nanoscale motion requires fastidious attention to instrumentation, passive controls, and experiment design. Most users have experience in motion control within the sphere of the microscale. In this paper we discuss what needs to be considered in the...
eCapture Pro: Comprehensive Software, Simplified
In addition to offering high-speed 10 GigE, 25 GigE, and 100 GigE Vision cameras that meet the demanding needs of applications such as volumetric capture/metaverse, sports technology, and machine vision, Emergent Vision Technologies now offers...
How to Manufacture Low-Cost Freeform Optics for High-Volume Imaging Applications
The benefits of implementing freeform optics are clear. They allow for custom aberration correction, redistribution of optical/mechanical tolerances, and even allow for a reduction in component count and system volume. In this whitepaper, Spectrum...
Fluorescence, Delayed Fluorescence and Phosphorescence Spectra of a TADF Emitter Measured Using the FLS1000 with a VPL Laser and Gated PMT Detector
Materials exhibiting thermally activated delayed fluorescence (TADF) have attracted widespread research attention as a new generation of high-efficiency emitters for use in Organic Light Emitting Diodes (OLEDs). In a TADF OLED, triplet excitons are...
Gemstone Identification Using Raman Microscopy
Raman microscopy is an ideal method for analysing gemstones and other geological samples. Its non-destructive nature and lack of sample preparation make it particularly advantageous for analysing all gemstones with no concerns about damage of...
Identification of Microplastics Using Raman Spectroscopy
This application note will investigate 3 polymers, polyethylene (PE), polytetrafluoroethylene (PTFE), and nylon-6, using the Edinburgh Instruments RM5 Raman Microscope.
Confocal Raman and Photoluminescence Microscopy for Forensic Investigations
Forensic investigations often study extremely small samples which may need analyses by multiple techniques. Confocal Raman and Photoluminescence (PL) Microscopy are well-suited techniques for dealing with such samples. This application note details...
Sb to Mn Energy Transfer Revealed using Time-Resolved Emission Spectroscopy (TRES)
Heterometallic metal halide hybrids hold great promise due to the potential for synergistic photo-physical properties depending on the choice of the constituent metal centres. In this application note time-resolved emission spectroscopy (TRES) with...
