LAMBDA HPX-L5 OPERATION MANUAL – REV. 1.03 (20161130)

The Lambda HPX-L5 is optimized for coupling to an optional 5mm liquid light guide, and off-
the-shelf microscope adapter. The HPX is expected to retain 95% of its original output at
5,000 hours, and 80% after 10,000 hours.
Because LEDs exhibit color shift with current change, the Lambda HPX was designed to dim
the LED using either PWM (Pulse Width Modulation) or current control. PWM control is
generally preferred for most applications as it allows the LED to run cooler. PWM switching
is at 28 KHz, high enough for use with most high speed cameras. For those with applications
intolerant of any pulsed output, dimming via current control is also available. PWM and
Current control are conveniently monitored and manually controlled via the display and
control knobs on the front panel of the MPX-L5. Integral shuttering time is 10 microseconds
to turn on and off. TTL input and output allows for triggering from either software or
directly from another device such as a camera or digital I/O board. PWM can also be
controlled externally via analog input. Active temperature monitoring insures that the LED
life is maximized.
Light output is in the visible spectrum from 400-729 nm. Special order units are available
with 630, 530, 460, and 405 nm wavelength specific LEDs. A two-channel system with any
combination of wavelengths can be configured by combining a Lambda HPX and Lambda
TLED/TLED+.
