Building a system comes down to (1) selection of appropriate base with specific functionality and type of control; (2) selection of LED head[s] and (3) focusing optics specific for the application. Functionality of base units include fast analog control (to generate any optical function, sine, saw, square, CW…); low noise CW control (for applications where ATC like or PWM algorithms may cause problem); and fast pulsed (digital) control (faster and more powerful then analog). Selection of the way the optical power is set include external digital/analog signal supplied thru connector (BNC/Twin BNC), or, for CW application, Built In Potentiometer/ Remote Potentiometer/ 2 level Switch). LED heads are currently available in two form factors: LEDHRxxx series, pre collimated with build in reflector and 1.2” pin spacing for close range illumination, and LEDHxxx series with 0.8” pin spacing for higher performance and wider selection of focusing optics. Many other models of LEDs can be adapted. The function of focusing optics is to direct the light to the certain spot size on certain distance as required and often custom designed for specific application. Most of new optics is backward compatible (fits the units previously shipped) Description Applications • Plug and play frame for LEDs • Interchangeable LED heads provided • 455nm, 475nm, 505nm, 530nm, 590nm, 617nm, 630nm, white 5500 K, white 3300 K • Selection of collimating optics/ attachments • Selection of base units • Fast analog control (some models) • Low noise CW control (some models) • Fast pulsed (digital) control (some models) • Narrow bandwidth or broadband • Wide field or focused output • Continuous, waveforms, or pulses to <150ns • Up to 400mW CW, x5 intensity short pulse • Accepts LEDs with 0.2”, 0.4”, 0.6”, 0.8”, 1”, 1.2” pin spacing • Mounting to standard and metric posts (8 32 and M4x0.75 threads in base unit) • Base unit diameter 1.450” (36.8mm) • Fluorescence excitation • High speed imaging • Synchronous detection • Machine vision • Biomedical optics Base Units Ordering information Base unit with built in low noise linear driver and manual analog control.

Analog channel has linear control and continuously variable output, with 1% input offset to ensure shutdown when signal is not applied. Digital channel has 2 level ON OFF control (active HI). Output current in the sum of outputs of both channels. Switch on the control panel selects which channel is addressed by input BNC connector, thus selecting Digital or Analog mode. There is an important difference between the output stages of Analog and Digital channels. Analog channel operates in current regulation mode using a feedback from the current sensor in the output stage. Digital channel, on the other hand, provides fast switching while the current is limited by the resistor (without active feedback). This is because the channels are optimized for different purposes: Analog channel is designed to convert the input voltage into output current as precisely as possible and as fast as reasonable but not to hurt the precision; while Digital is optimized for switching the current to MAX level and back to 0 as fast as possible. As a side effect, the current in Digital mode varies slightly for different LED head; while the Analog channel current is regulated to be the same. Base unit accepts LED heads with 0.2 1.2 inch pin spacing. (LEDH, LEDHR). Accepts focusing optics and attachments mounted on LED head directly and models that have index “36” in a part number.
