Chapter 3 Description
The SM1L10H is an actively heated lens tube that is compatible with all Thorlabs’
SM1 series lens tubes and accessories, as well as Thorlabs’ TC200 Heater
Controller.
This device allows for m ounting most of o ur 1” diameter optics and provides a
heating capability that will prevent condensation from for ming on the optic, or
allow you to take advantage of various thermal effects inherent in some optics.

Chapter 4 Operation
Normal Operation and Use
Caution! Internal Lens tube temperatures will be very hot! Handle with
care.
1. Install the 1” Optic into SM1L10H Heater as follows:
a) Loosen the three button head cap screws on the end cap with the
internal threads. It is not necessa ry to completely remove these
screws
b) Holding the scre ws with your fingers, slide t he end cap ou t of the
heater.

c) Place the optic into the le ns tube so it is se ated against the SM1
retaining ring that is already installed in the tube.
d) Secure the optic by threading in a second SM1RR retaining ring
(provided with the heater).
e) Replace the end cap. Orient the grooved inner surface towards the
inside of the heater and slide the screws into the slots.
f) Tighten each screw until just snug. Do not over-tighten the screws
g) NOTE: DO NOT attempt to install the opt ic without removing the
end cap first. T he SM1RR retain ing ring will NOT thread correctl y
from the end cap threads to the lens tube threads.

2. Locate unit on a solid, dry working surface. Unit should be secured to a
standard optical breadboard using a T horlabs’ post and base in
conjunction with a Thorlabs’ LMR1 adapter (not included).
3. Connect the heater to a n appropriate heater controller. The Hirose
connector is pin compatible with Thorlabs’ TC200 Heater Controller.
Please refer to Appen dix A for pin designations if you are using a third
party controller.
4. Operate the heater in accordance with the controller that is powering it.
IMPORTANT NOTE: The internal heating element is pr otected by a t hermal
switch that acti vates at 80 °C. At this temperature t he thermal switch will open
the connection to the heating element, causing the unit to cool down. The reset
temperature on the switch is approximately 40 °C. Once the switch cools down to
the reset point it will re-close and connect the h eating element to the power
source. The unit will then cycle on and off until the problem is corrected. Possible
reasons for th e heater to exceed 80°C include: a failed thermistor, o pen or
broken thermistor wires or connections, or improperly set control temperature.
Additional SM1 compatible lens tubes and accessories can be installed onto the
SM1L10H. Male and female threads are provided on each end of the unit. Please
take care when threading extensions onto the SM1L10H as each e nd cap is
made from Delrin and can easily cross thread or strip if over tightened.

Chapter 7 Regulatory
As required by the WEEE (W aste Electrical and Electronic Equipment Directive)
of the European Community and the corresponding national laws, Thorlabs offers
all end users in the EC the possibility to return “end of life” units without incurring
disposal charges.
• This offer is valid for Thorlabs electrical and electronic equipment:
• Sold after August 13, 2005
• Marked correspondingly with the cr ossed out
“wheelie bin” logo (see right)
• Sold to a company or institute within the EC
• Currently owned by a com pany or institute
within the EC
• Still complete, not disass embled and not
contaminated
As the WEEE directiv e applies to self contained
operational electrical and electronic products, this end of
life take back service does not refer to other Thorlabs products, such as:
• Pure OEM products, that means assemblies to be built into a unit by the
user (e.g. OEM laser driver cards)
• Components
• Mechanics and optics
• Left over parts of units disassembled by the user (PCB’s, housings etc.).
If you wish to return a Thorlabs unit for waste recovery, please contact Thorlabs
or your nearest dealer for further information.
Waste Treatment is Your Own Responsibility
If you do not return an “end of life” unit to Thorlabs, you must hand it to a
company specialized in waste recovery. Do not dispose of the unit in a litter bin
or at a public waste disposal site.
Ecological Background
It is well known that WEEE pollut es the environment by releasing toxic products
during decomposition. The aim of the Eur opean RoHS directive is to redu ce the
content of toxic substances in electronic products in the future.
The intent of the WEEE directive is to enforce the recycling of W EEE. A
controlled recycling of end of life products will thereby avoid negative impacts on
the environment.
