New LED Light Source for Transmitted Light

Sutter Instrument Company, Society for Neuroscience booth #412, have introduced a new Lambda TLED™ LED light source that can be used in the transmitted light path of a microscope or other applications with similar requirements.

This basic system consists of an LED mounted on a special black-anodized aluminum heat sink and a controller. The Lambda TLED controller has intensity control and on-off control via a switch or TTL logic. The on-off time is < 25 µsecs when using TTL control. The Lambda TLED is expected to have very stable output that will last in excess of 10,000 hours.

The Lambda TLED uses a high-output white light LED making it a suitable light source for contrast methods including Phase and Differential Interference Contrast (DIC). The controller runs off a rugged modular universal power supply similar to those used for laptop computers.

Each system includes an optical mounting adapter for the microscope and detailed installation instructions. Mounting adapters are designed to fit most models of Nikon, Olympus, Zeiss and Leica microscopes. Custom adapters for the Lambda TLED are available at an additional cost. As an alternative to the standard white-light LED, we have options for an IR-LED which is suitable for experiments requiring IR-DIC.
