M660L4 In Stock

The M660L4 by ThorLabs is a high-performance mounted LED that is perfect for a wide range of applications. This LED has a 660 nm nominal wavelength and exceeds an incredible 940 mW of power output, making it a formidable source for illumination. The M660L4 is securely mounted on a Ø30.5 mm heat sink at the end, ensuring optimal temperature management and preventing degradation of optical power due to increased LED temperature.

One of the standout features of the M660L4 is its built-in EEPROM chip, which saves important LED data, including wavelength, forward voltage, and current limit. This data can be utilized to implement smart safety features when paired with a compatible LED driver, providing an extra layer of protection and reliability in your setup. To ensure the best performance, the M660L4 requires a constant current supply of no more than 1200 mA, with a forward voltage of 2.6 V. It is important to provide adequate air ventilation to avoid reduced lifetime, overheating, and optical power drops of the M660L4. The LED's characteristic switch-on behavior is also influenced by heat dissipation in the environment conditions, in addition to the LED's specific properties.

The M660L4 is designed for easy integration into your existing setup. It is compatible with adjustable collimation adapters, allowing seamless integration into SM2-threaded components with an internal SM2 (2.035"-40) thread adapter. The LED also features a 4-Pin female mating connector for custom power supplies and a standard male M8x1 sensor circular connector, providing versatility and convenience in your setup. Please note that after switching on, the M660L4 may experience a warm-up period, causing a temporary decay in optical power. However, the robust heat sink of the M660L4 ensures efficient thermal management, reducing power loss as the LED reaches its equilibrium temperature.
