Don’t forget to apply for our Annual Earth Day Promotion!
Earth Day 2017 may be past, but Lumencor’s support for a brighter, greener planet continues year round. We’re awarding TEN FREE Lumencor light engines® for fluorescence microscopy to deserving participants.
How to Qualify
- Make a minimum purchase of $10,000 of any light engine product (accessories do not apply) DIRECTLY from Lumencor, Inc. in a single order no later than JUNE 30th, 2017 and your purchase could be rewarded with the shipment of a FREE SOLA light engine®.
- TEN SOLA light engines, FIVE SM’s and FIVE SE’s, are available on a first-come, first-served basis. Limit one light engine per participant. ~$5,000 – $7,500 value.
- These SOLA light engines are gently used; in the spirit of Earth Day we want to repurpose these fully functional units. Light engines ship in “like new” condition with a full end user warranty and certificate of conformity, per manufacturer’s specification.
- Orders must be submitted with a statement as to why Lumencor’s products are meaningful to your work. Is it the brightness?…the stability?…the low-energy consumption?…the mercury-free nature of Lumencor lighting?…the elimination of all maintenance, including no replacement parts?
- Awardees must provide an image or video clip produced with the aid of a Lumencor light engine. Images should be submitted within 60 days of receipt of your gift.
Some restrictions apply. Visit our Annual Earth Day Promotion page for more details.
Time for a Change
With Lumencor’s SPECTRA, SPECTRA X or AURA light engines installed on your microscope, the time for a change can be very short indeed — less than one millisecond.
Fast switching between color channels is a key requirement for applications such as multicolor fluorescence microscopy, optogenetics and “virtual color” transmitted light imaging (superimposed red, green and blue images taken with a monochrome camera). Switching via serial commands is limited to around 50 ms by factors including the host computer operating system, processor speed and serial port baud rate. Faster switching requires TTL hardware control.
In the example shown here, the cyan (485/25 nm) and green (560/32 nm) channels of an AURA light engine are triggered by TTL signals from two synchronized pulse generators. The resulting light output is detected by a photodiode connected to a digital oscilloscope. In a typical optogenetics application, the alternating cyan (~0.5 ms) and green (~3 ms) output pulses would be directed through an optical fiber for cyclical activation and inhibition of neurons expressing channelrhodopsin-2 (ChR2) and halorhodopsin (NpHR).

The Portland Backpack Lunch Program is a local non-profit organization that provides weekend meals to students in need. These children rely on federally-funded school lunches during the week and often go hungry on the weekends. Since its inception in 2008, the Portland Backpack Lunch Program has provided over 95,000 meals every Friday to low-income students.
Lumencor is excited to partner with the Portland Backpack Lunch Program once again in 2017. On April 21st, our entire team got together and packed 650 lunches and 650 breakfasts. We wrote notes of encouragement for the students as well. We are proud to give back to the community through a program that not only provides food to children in need, but also fosters an environment of caring and connected individuals.
If you are interested in volunteering or donating to this worthy cause, find the Portland Backpack Lunch Program on Facebook for more information, or give them a call at 503.284.4647. The Portland Backpack Lunch Program primarily serves Northeast Portland students in the Tina Clegg Head Start, Woodlawn, King, and Scott schools.
