Microscope light source Lambda TLED

LED

The Lambda TLED and TLED+ are stand-alone LED light sources that can be used with the transmitted light path of a microscope or in other applications with similar requirements. The basic system consists of an LED mounted on a special black-anodized aluminum heat sink and a controller. Both TLED and TLED+ controllers are powered by a rugged modular universal power supply. The controllers provide intensity control and on-off control via a toggle switch or TTL logic. The on-off time is < 25 µsecs when using TTL control. In addition to digital input control, the Lambda TLED+ has an analog input to modulate the LED intensity. The Lambda TLED and TLED+ are expected to have stable output that will last in excess of 50,000 hours. The Lambda TLED and TLED+ can be ordered with a high-output white light LED making it a suitable light source for contrast methods including Phase and Differential Interference Contrast (DIC). As an alternative to the standard white-light LED, we have several options available including an IR-LED which is suitable for experiments requiring IR-DIC. Please contact Sutter for details. Our dual channel Lambda TLED+ option combines two high power LEDs into a single light path. The TLED-DC includes a 460 nm LED for stimulation, while the second channel passes the phosphor emission from a white light LED. The white light channel can be used to access spectra between 510 nm to 630 nm and is suitable for a variety of applications. Both channels are driven by individual TLED+ controllers and can be triggered, also individually, by a TTL signal. Alternate wavelength configurations are available.
