Lambda HPX-L5 - High Power LED Light Source with Liquid Lightguide

Sutter newest high power LED light source, the HPX, was transformed into the Lambda HPX-L5 using a liquid light guide linked design. The liquid light guide has an inbuilt heatsink with a whisper fan that enables for LED cooling. Compared to the direct mount liquid-cooled version, this requires less maintenance. The Lambda HPX-L5 was built around a single 90W 3 mm LED die and, when used with the same light guide, produces brightness similar to that of a 150W xenon arc lamp. The Lambda HPX-L5 is designed for connecting to commercially available microscope adapters and an optional 5 mm liquid light guide. After 60,000 hours, the HPX is anticipated to retain 70% of its initial light output.

The Lambda HPX was created to dim the LED using either PWM or current regulation since LEDs exhibit color shift with current change. For the majority of situations, PWM will be preferred since it keeps the LEDs running cooler. 28 kHz PWM switching is high enough for usage with the majority of high-speed cameras. Dimming via current regulation is also an option for those whose applications cannot tolerate any pulsed output. On the front panel display, PWM and current information are easily accessible and manually configurable via control knobs. The integral shuttering time to turn on and off is 10 microseconds. TTL input and output provide triggering directly from a different device, such as a camera or digital IO board, or via software. Analog input can also be used to control PWM externally. The LED life is maximized thanks to active temperature monitoring.

Between 430 nm to 700 nm, visible light is produced. There are special order units available with wavelength-specific LEDs at 630 nm, 530 nm, 460 nm, and 405 nm. It is also possible to establish a two-channel system with any combination of wavelengths by combining the Lambda HPX-L5 and Sutter FLED.
