Modular Spectrometer Delivers High Performance in Compact Footprint
In this application note, we share spectra that demonstrate performance characteristics of the Ocean SR2, a modular UV-Visible spectrometer. We evaluate the effectiveness of the Ocean SR2 for measuring absorbance of optical filters and demonstrate how its high optical resolution performance and balanced (or “flatter”) spectral response help to mitigate typical modular spectrometer performance trade-offs.
Improving the Future of Smart Agriculture with Spectroscopy
Climate change and population expansion have a direct impact on agriculture. An increasing number of people need to be fed, but changing weather patterns can cause complete crops to fail. Inevitably, farms must produce more with less and frequently...

Life Sciences Instrumentation - The Key to Health Care Transformation
The World Health Organization estimates that the number of people over age 60 will increase from 1 billion in the year 2019 to more than 2 billion in 2050, with life expectancy rising as well. Most of these people will live in heavily populated,...
Spectroscopy for Gas Analysis and Sensing
A variety of spectroscopic techniques are used in gas analysis and sensing – increasingly important fields – crucial in atmosphere monitoring, emission control, and industrial processes efficiency. They are implemented more and more often a mass...
High Absorbance Scanning with the PerkinElmer LAMBDA 850+ UV/Vis and LAMBDA 1050+ UV/Vis/NIR Spectrophotometers
This application note describes the procedure for high absorbance scanning with the reference grade PerkinElmer LAMBDA™ 850+ UV/Vis and LAMBDA 1050+ UV/Vis/NIR double monochromator spectrophotometers.
Spatiospectral Nanoimaging of Surface Phonon Plasmons
Surface plasmon polaritons (SPPs) in 2D materials enhance light-matter interaction and enable development of super lenses, subwavelength metamaterials, and other photonic devices. In-situ characterization of polaritonic excitations requires a...
Measuring Absorptance and Refractive Index of Thin Films with UV/Vis/NIR
An optical coating consists of a combination of thin film layers that create interference effects used to enhance transmission or reflection properties for an optical system. In this paper we will show how the absorptance, refractive index, and film...
Are You Facing any Problems Securing Optical Parts?
You need just a couple of pieces for trial. You need to achieve an exact specification. You need to keep the same quality in every order. You cannot find the best fit material for your design. You always need the material certificate. You need to...
Diamonds are Forever: Using NIR to Find the Fakes
Cubic zirconia is easy and inexpensive to make and the diamond industry has long considered it an existential threat. Consider a diamond crusted band, what if some of those diamonds are actually cubic zirconia? Most people would never be able to...
Industrial Equipment Failure Analysis Using FT-IR Microscopic Techniques
This work demonstrates that FT-IR microscopy analysis is capable of determining the cause of failures of many different pieces of industrial equipment. This analysis can then allow the user to take preventative action measures in order to improve...
Curing of an Optical Adhesive by UV Irradiation by DSC
