M395L3 In Stock

The ThorLabs M395L3 is a high-powered, mounted LED that delivers exceptional performance and stability for a range of optical applications. With a dominant wavelength of 395 nm and an output of more than 420 mW of power, this LED is a reliable and versatile solution for the user’s optical needs.

The M395L3 features a heat sink equipped with internal SM1 (1.035"-40) threads, which makes it easy to integrate with other Thorlabs components. The heat sink has a diameter of 1.20", which is the same as an SM1 lens tube. Additionally, the integrated EEPROM chip in each LED stores vital information about the LED, including current limit, wavelength, and forward voltage, which can be easily read with compatible controllers. One of the standout features of the M395L3 is its exceptional thermal stability properties. This eliminates the issue of degradation of optical output power due to increased LED temperature, providing consistent and reliable performance over time. Moreover, with a long lifetime of over 10,000 hours, this LED is a durable and dependable choice for the user’s optical needs.

The M395L3 is also compatible with collimation adapters that contain an AR-coated aspheric lens. The COP adapters are designed to mate with the epi illumination ports on Leica DMI, Nikon Eclipse, Olympus IX/BX, and Zeiss Axioskop microscopes. Alternatively, ACP2520 collimation adapters have an internally M34 x 0.5 threaded housing and use a Ø25 mm optic in a translating carriage to provide collimation adjustment of the M395L3. For easy integration of the LED with compatible components that are SM2-threaded and microscope port adapters, each collimation adapter comes with an external M34 × 0.5 to internal SM2 thread adapter.
