Light BYTES – June 2021: Proud to be recognized as a Top 10 Photonics Solutions Provider by Semiconductor Review Magazine

Proud to be recognized as a Top 10 Photonics Solutions Provider by Semiconductor Review Magazine

Control of the spatial, spectral and temporal characteristics of light is becoming increasingly important for defect analysis and device testing in semiconductor manufacturing. Well-known limitations of arc lamps and incandescent bulbs are their limited operating lifetimes and lack the flexibility, necessary for facile integration in modular instrument designs. Consequently, OEM instrument designers and manufacturers are turning to Lumencor’s solid-state illumination products for solutions. In recognition, Lumencor has recently been awarded a Top 10 Photonics Solutions Provider, in the prestigious annual 10-company listing compiled by Semiconductor Review Magazine. Therein, notable leaders at the forefront of providing photonics solutions and transforming businesses are distinguished for their creativity and efficacy. An accompanying feature article appears in the magazine’s June 2021 issue.

Defect analysis and device testing in semiconductor manufacturing requires illumination that delivers reliable, reproducible, consistent performance. Lumencor’s precision manufacturing results in unsurpassed reproducibility from one light engine to the next. An analysis of test data from 25 SOLA Light Engines® shows a standard deviation of only 70 mW from average, equating to a 2% coefficient of variance. Such inter-instrument reproducibility is unheard of with regard to arc lamps and the bulbs on which they depend.

Light BYTES – March 2021: MAGMA Light Engine®: Solid State Illumination for Solar Test Platforms

MAGMA Light Engine®: Solid State Illumination for Solar Test Platforms

Artificial light sources are essential for performance validation in photovoltaic device manufacturing and for characterization of properties such as photoconductivity and quantum efficiency in the development of new photovoltaic materials. Traditionally, characterization of photovoltaic devices has employed xenon arc or halogen lamps to approximate the solar spectrum. However, their spectral output is not readily amenable to controlled adjustment, and long duration (weeks to months) tests are limited by their relatively short operating lifetimes. Lumencor’s MAGMA Light Engine employs modern solid state illumination technology to overcome these limitations. Within a compact 15 cm x 35 cm footprint, the MAGMA Light Engine incorporates 21 individually addressable LED light sources, ranging from 365 nm to 1050 nm, under the control of an onboard microprocessor. The LED outputs are merged into a common optical train directed to the light output port on the front panel. Adjustment of the relative output intensities of the 21 elements of the LED array enables synthesis of user-specified spectral distributions, such as the AM1.5G solar spectrum.

Light BYTES – February 2021: Nature Method 2020 Method for the Year Features Lumencor’s CELESTA

Method of the Year: MERFISH Imaging using the CELESTA Light Engine®

Nature Methods journal recently selected spatially resolved transcriptomics as Method of the Year for 2020.  Spatially resolved transcriptomics is a collective term for a set of techniques directed towards a single goal – molecular level characterization of single cells within the spatial context of the tissues that they inhabit. This maintenance of spatial context is crucial for understanding key aspects of cell biology, developmental biology, neurobiology and tumor biology.  MERFISH (multiplex error robust fluorescence in situ hybridization) is one of the most prominent spatially resolved transcriptomics techniques.  MERFISH is an imaging technique that profiles cell populations based on identification of thousands of RNA transcripts per cell.  The CELESTA Light Engine is an ideal and widely-adopted illumination source for this application.  In a recent paper published in Cell [1], Xiaowei Zhuang and co-workers at Harvard University used MERFISH and a CELESTA Light Engine to simultaneously image more than 1000 genomic loci with nascent RNA transcripts of more than 1000 genes residing in these loci and landmark nuclear structures, including nuclear speckles and nucleoli. This approach allows exploration of the relationship between chromatin organization, transcriptional activity, and nuclear structures in single cells.  The paper also provides detailed descriptions of the procedures for performing the multiple cycles of probe hybridization and imaging required for multiplexed detection of thousands of DNA and RNA sequences.

MERFISH (multiplex error robust fluorescence in situ hybridization) is one of the most prominent spatially resolved transcriptomics techniques for which Lumencor’s CELESTA Light Engine is playing a critical role.

Light BYTES – December 2020: Introducing the newly updated family of SOLA light engines®

Updated SOLA light engines for 2021 and Beyond

You asked and we delivered! Lumencor is proud to introduce the newly updated family of SOLA light engines that will continue to set the standards for performance and reliability in white light illumination. This product line now includes 4 standard models that are differentiated by the number of sources and spectral output: SOLA, SOLA FISH, SOLA U-nIR and SOLA V-nIR light engines. The SOLA light engine provides white light output for excitation of DAPI, GFP/FITC, YFP, Cy3, mCherry, Cy5 and spectrally similar fluorophores. In the SOLA FISH light engine, output in the 475–600 nm region is red-shifted to provide optimal excitation for SpectrumGreenTM, SpectrumRedTM and other fluorophores commonly used for fluorescence in situ hybridization (FISH) analysis in cytogenetic testing laboratories. The SOLA V-nIR and U-nIR light engines offer the broadest spectral coverage, including near infrared (nIR) output for excitation of fluorophores such as Cy7 and ICG, and for other applications that benefit from the enhanced tissue penetration of nIR light.

All SOLA light engine models now include:

  • USB and electronic shutter control connections
  • Linearized intensity control
  • Active output stabilization
  • Long operational lifetimes
  • 24-month warranty

The 3 mm liquid light guide required for delivering the SOLA light engine output to microscopes or other bioanalytical instruments is now automatically included with all purchases. To request a sales quotation for any (or all) of the four new SOLA light engine models, please submit our online quote request form today!

Light BYTES – November 2020: Intensity Control Linearity in Lumencor’s New Generation of Light Engines

Lumencor’s new Generation of Light Engines: Intensity Control linearity

AURA, RETRA, SPECTRA, CELESTA and ZIVA light engines, as well as the newly refreshed SOLA light engine for 2021, incorporate on-board microprocessors, providing impressive advances in control and monitoring capabilities. One such advancement is linear intensity control. Each of these illuminators generate optical power that has a precisely linear relationship to intensity settings across all colors, providing more quantitive and predictable responses for users. In the case of white light, constant color temperature is achievable regardless of output power. Just another reason customers who care about performance come to Lumencor for solid state illumination.
