Safety
Attention
All statements regarding safety of operation and technical data in the
instruction manual will only apply when the unit is operated correctly.
The mounted LED of the MxxxLx series must not be operated in explo-
sion endangered environments!
The mounted LED of the MxxxLx series must only be connected with
duly shielded connection cables.
Only with written consent from Thorlabs may changes to single compo-
nents be carried out or components not supplied by Thorlabs be used.
Do not remove covers!
Refer servicing to qualified personal!
Warnings
Inappropriate use of any Thorlabs High Power LED product could result
in permanent eye damage.
To prevent injury, these products must be used in accordance with the
International Standard “Photobiological Safety of Lamps & Lamp
Systems” CEI IEC 62471.
When Thorlabs high power LED’s are used in microscope applications
as a replacement for mercury Vapor lamps, the same precautions
should be taken as those applying to mercury Vapor lamps.
When Thorlabs High Power LED’s are used in other applications, they
should be used in accordance with CEI IEC 62471.

Warnings
The M365L1, the M385L1 and the M405L1 contain an UV light LED! The
LED radiates intense UV light during operation. Precautions must be
taken to prevent looking directly at the UV light with unprotected eyes.
Do not look directly into the UV light or look through the optical system
during operation of the device. This can be harmful to the eyes even for
brief periods due to the high intensity of UV light.
If there is a possibility of reflection of the UV light, UV light protective
glasses must be used to prevent the UV light entering the eye.
If viewing the UV light is necessary, UV light protective glasses must be
worn to avoid eye damage by the UV light.

Warnings
The M850L1 contains an IR light LED! The LED radiates intense IR light
during operation. Precautions must be taken to prevent looking directly
at the IR light with unprotected eyes.
Do not look directly into the IR light or look through the optical system
during operation of the device. This can be harmful to the eyes even for
brief periods due to the high intensity of IR light.
If there is a possibility of reflection of the IR light, IR light protective
glasses must be used to prevent the IR light entering the eye.
If viewing the IR light is necessary, IR light protective glasses must be
worn to avoid eye damage by the IR light.
Cautions
During normal operations, the casing temperature of Thorlabs High
Power LED products will rise by up to 25°C (45°F) above ambient
temperature.
To prevent higher case temperatures, the products should be oper-
ated without hindrance to air movement surrounding the convective
cooling fins.

1 General Information
Developments in the design of Light Emitting Diodes (LEDs) have resulted in devices
that have significantly more power and can rival certain halogen lamps and gas
discharge lamps. Power levels are now high enough for LEDs to present a practical
alternative to these traditional light sources. They offer several advantages, including
better stability, longer life, lower cost of replacement and lower risk (no glass bulbs to
break).
All of Thorlabs mounted & heatsinked uncollimated LED assemblies are compatible
with our range of LED Collimator assemblies and can mate to the standard and epi-
illumination ports on most readily available commercial microscopes. A range of
different colors (dominant wavelengths) are available, making these devices
applicable for wide field fluorescence microscopy when combined with suitable
excitation and emission filters.
Each LED module has a flying lead terminated in a 4 pin M8 plug, compatible with
Thorlabs series of LED drivers.
2 Getting Started
2.1 Unpacking
Inspect the shipping container for damage.
If the shipping container seems to be damaged, keep it until you have inspected the
contents and you have inspected the MxxxLx mechanically and electrically.
Verify that you have received the following items:
•MxxxLx Mounted LED assembly
•Operation Manual
2.2 Preparation
Before you connect tie LED to a LED driver, check if the LED can handle the
maximum LED current or the LED current limit is configured correctly. The MxxxLx
features an EEPROM which contains the maximum LED current, wavelength and
forward voltage of the LED.
1. Connect the MxxxLx to the LED driver.
2. Check the current limit.
3. Switch on the LED driver.

2.3 Physical Overview
Figure 1 Mounted LED Assembly
The following picture shows the male connector of the MxxxLx mounted LED
assembly. It is a standard M8x1 sensor circular connector. Pin 1 and 2 are the
connection to the LED. Pin 3 and 4 are used for the internal EEPROM in the MxxxLx
series. Do not use these connections when using a different LED driver than
Thorlabs series of LED drivers.
Figure 2 Male Connector of the MxxxLx
The LEDC series consists of the MxxxLx mounted LED and a collimation assembly
compatible for one of the following microscopes:
•Olympus BX and IX microscopes
•Leica DMI microscopes
