CONTINUOUS 2-INCH AIR-COOLED LED LIGHT SOURCE

Product ID: LM2X-DM-XXX
The continuous 2-inch, air-cooled LED light source provides uniform, stable illumination, for pressure and temperature sensitive paint measurements. The LED is designed for radiometric acquisition systems. It can operate continuously (DC) or in a long-pulsed mode. The operation mode is set using an external toggle switch. In long-pulsed mode, the pulse width and frequency are set by sending an external TTL signal to the BNC trigger input. The duty cycle may be set from 0% to 100%. The light distribution from the unit is approximatly Gaussian for distance greater than 18-inches [45-cm] from the source. The units are available in standard wavelengths of 400-nm and 460-nm, however, other wavelengths are available upon request.

Ordering information: LM2X-DM-XXX (LED head with DC/long pulse driver –XXX denotes wavelength)

LIFETIME 2-INCH AIR-COOLED LED LIGHT SOURCE

Product ID: LM2X-DMHP-XXX
The lifetime 2-inch, air-cooled LED light source provides uniform, stable illumination, for pressure and temperature sensitive paint measurements. The LED is designed for lifetime acquisition systems. The system is overdriven, giving it a higher peak power per pulse than the continuous LED system. Pulse width and frequency are set by sending an external TTL signal to the BNC trigger input. Because it is overdriven, the duty-cycle is limited to 5%. The maximum pulse width is limited to 1-ms. A governor circuit in the system prevents the system from exceeding 5% duty cycle, which could damage the LED. The light distribution from the unit is approximatly Gaussian for distances greater than 18-inches [45-cm] from the source. The units are available in 400-nm and 460-nm, however, other wavelenths are available upon request.

Ordering information: LM2X-DMHP-XXX (LED head with short-pulse/high-power driver –XXX denotes wavelength)

SPECIFICATIONS

Output power >1.1 W
Input 48V2.5A
Stability ~0.1 % per hour after warm-up
Maximum duty cycle 5%
Rise time (10% - 90%) < 200 ns
Fall time (90% - 10%) ~ 100 ns
Operating temperature range -10°C to 60°C
Wavelength 400-nm and 460-nm (Standard)
FWHM +/- 18-nm

CONTINUOUS 4-INCH AIR-COOLED LED LIGHT SOURCE

Product ID: LM4X-DM-XXX
The continuous 4-inch, air-cooled LEDs offer uniform, stable illumination with excellent output power. The unit operates continuously or in long-pulse mode, designed for radiometric systems using the continuous/long-pulse driver (module for radiometric). The operation mode is set using an external toggle switch. In long-pulsed mode, the pulse width and frequency are set by sending an external TTL signal to the BNC trigger input. The duty cycle may be set from 0% to 100%. The 4-inch LED offers a 3-4X increase in power over the continuous 2-inch, air-cooled LED, 5X faster rise and fall times for pulsed operation, and increased temperature range of operation. The light distribution from the unit is approximately Gaussian for distances greater than 18-inches [45-cm] from the source. The units are available in 400-nm and 460-nm, however, other wavelenths are available upon request.

The lifetime 4-inch, air-cooled LED light source provides uniform, stable illumination, for pressure and temperature sensitive paint measurements. The LED is designed for lifetime acquisition systems. The system is overdriven, giving it a higher peak power per pulse than the continuous LED equivalent. Pulse width and frequency are set by sending an external TTL signal to the BNC trigger input. Because it is overdriven, the duty-cycle is limited to 5%. The maximum pulse width is limited to 1-ms. A governor circuit in the system prevents the system from exceeding 5% duty cycle, which could damage the LED. The maximum pulse width is limited to 1-ms. These units supersede the LM2X-DMHP-XXX LEDs as they offer a 3X increase in power, 5X faster rise and fall times for pulsed operation, and increased temperature range of operation. The light distribution from the unit is approximately Gaussian for distances greater than 18-inches [45-cm] from the source. The units are available in 400-nm and 460-nm, however, other wavelengths are available upon request.
