Lumencor’s Best Practices
During COVID-19

Lumencor’s manufacturing operations remain healthy and active. While daily operations are inevitably constrained by measures taken to foster good health and minimize the transmission of COVID-19, productivity remains high. Minimal component shortages have developed as shelter-in-place practices have dampened our suppliers’ activities. However, we expect our supply chain will likely suffer additional shortages. Lumencor’s practices now include the quarantine of all receivables as our first commitment is to ensure the safety of our employees while safeguarding their work. In some cases, that may mean that our deliveries to customers will be delayed. We will do our best to inform all customers with pending orders of changes to anticipated shipment dates. Please notify us of any urgency around your order and we will do our very best to assist.

Please be assured that we are watching and managing your business with great care during the current emergency. Please contact to our sales, customer service or technical support representatives if you have any questions or wish to discuss deliverables for your organization’s needs.


A Spectacular Triple Play: LIDA Light Engine®, NIS Elements and sCMOS Cameras for Color Light Microscopy

For histologists, clinical pathologists and anyone seeking improvements in the speed, sensitivity and precision of transmitted light microscopy, Lumencor’s LIDA light engine in combination with Nikon NIS Elements software enable high-speed color imaging data without the need for a dedicated color camera. Instead, monochrome images generated by sequential triggering of the LIDA’s red, green and blue light sources by a sCMOS camera are processed by NIS Elements, delivering video-rate color output. These capabilities allow rapid and fully automated imaging of large tissue sections, as illustrated below. The software also enables convenient switching between camera-synchronized RGB illumination and white-light illumination for ocular viewing. Our application note RGB Color Imaging using the LIDA Light Engine and NIS Elements outlines hardware set-up for Hamamatsu ORCA-Flash4.0 and Andor Zyla sCMOS cameras and provides instructions for image acquisition control using NIS Elements software.

Precise power regulation on each of
Lumencor’s newest and brightest light engines:
AURA®, SPECTRA®, CELESTA®, and ZIVA light engines®

In addition to high power and intense brightness, output power regulation is one of the many advanced control features incorporated in Lumencor’s next generation products: SPECTRA, AURA, CELESTA, and ZIVA light engines. To use power regulation, a desired power reference value in milliwatts is entered in the onboard control GUI, as shown in the attached link. To activate power regulation, click the padlock icon next to the reference power value. Gray shading of the padlock icon and the reference power value shows that power regulation is active for the selected output channel. When power regulation is active, the intensity setting for the channel is controlled by the onboard microprocessor, based on feedback from the light engine’s reference photodiode array. The microprocessor continuously adjusts the intensity setting so that the output power matches the power reference value set by the user.

Output power regulation settings in the CELESTA light engine control GUI

Performance of the output power regulation feedback system of a SPECTRA light engine is illustrated below. The response time of the feedback system is approximately one second. Output power regulation allows users to eliminate variations in light output due to temperature fluctuations and other environmental factors in photometric and quantitative imaging applications where reproducibility and accuracy are essential.
