Excitation Light Source

LEX9 is a highly powered and highly stable LED light system developed for biological research. Two different LED units can be installed inside. The LED units use LEDs in the visible to near-infrared light range that have higher output than conventional ones, and various wavelengths can be selected to match fluorescent probes.

It is possible to manually turn on/off one or two wavelengths, or alternately turn on two wavelengths in frame synchronization with a high-speed camera system. LEX9 is ideal as an excitation light source for high-speed fluorescence imaging.

Applications:
- Excitation light source for fluorescence imaging
-- GCaMP imaging
(Hemodynamic correction using 405nm/460nm)
-- Calcium imaging
-- Voltage sensitive dye imaging
-- Intrinsic optical signal (IOS) imaging

- Light stimulation for Optogenetics
-- Channelrhodopsin (ChR2)
-- Halorhodopsin (NpHR)
-- Arch and Chrimson, etc.

- Other fluorescence imaging
-- Experiments requiring bright and highly stable light
-- Experiments requiring wide area illumination

Main Features:
- Higher power: Improve S/N ratios
- Highly stable: Minimize unnecessary noise when imaging biological signals
- Dual wavelength excitation: Two wavelengths can be acquired with one camera
- Fast switching: For high-speed imaging and pulsed light stimulation
- Expandability: Compatible with various fluorescent probes
- Wide area illumination: Illuminate entire area at low magnifications
