Thorlabs' High-Power IR Emitters are pulsable, thermal blackbody sources that feature a 40 mm2 emitter area and >0.9 emissivity over a broad spectral range. Each emitter features a free-standing monolithic radiating element, which offers improved efficiency as well as better mechanical stability and shock resistance compared to wound filaments. The radiating element is made of high-melting point metal with a nanostructured surface that increases the optical emissivity. To achieve maximum efficiency, each emitter also includes an integrated reflector that directs the backside emitted radiation towards the front of the housing.
The emitters are available with open housings (HPIR101) or hermetically sealed with soldered windows made from sapphire (HPIR102), barium fluoride (HPIR103), or calcium fluoride (HPIR104). Versions with soldered windows are suitable for the measurement of flammable gases. The soldered windows are leak tested and offer improved long term stability compared to conventional glued windows. All sealed IR emitters are filled with nitrogen gas; please contact Tech Support for other gas fillings. The HPIR103 and HPIR104 models feature a Winston cone collimator, narrowing the emission angle of the emitted radiation.

HPIR102 Bulb Mounted in HSLT2 Heatsink Lens Tube
with CaF2 Plano-Convex Lens Using HPIRM Mounting Adapter
The HPIRM Mounting Adapter has external SM1 (1.035"-40) threads that enable the HPIR bulbs to be integrated into our Ø1" Lens Tube Systems and SM1-Threaded Kinematic Mounts. The bulb is held in the HPIRM mount using an SM17RR Ø17 mm Retaining Ring (included), which can be tightened using our SPW801 Adjustable Spanner Wrench. The adapter can be installed in an SM1-threaded lens tube or mount using the SPW909 or SPW801 Spanner Wrenches.
Please note that the housing of the emitter will heat up during operation. Although operation without a heatsink is possible without damaging the emitter, we recommend using a suitable heatsink like the HSLT2 passive-heat-sink lens tube in combination with the HPIRM mounting adapter for long term operation. An example is depicted to the left.
While these emitters can be driven by any power source respecting the current and power limits given in the Specs tab, we recommend using our basic LEDD1B driver. The wires of the driver's connection cable can be attached directly to the leads of the emitter.

 (posted 2024-08-08 12:25:41.987) We are looking to purchase a mid-infrared source for characterizing samples using the OSA207. I previously bought the SLS203F, but its intensity cannot be detected by the OSA207. Therefore, we are searching for another light source that covers the 3-6 µm spectrum of interest. Could you please check if the HPIR101 lamp can provide a strong signal when used with the OSA207 (free space coupling)?
Thank you for your assistance. hchow

Thank you for your feedback. Unfortunately we can´t provide zemax files for our thermal emitters. I reach out to you in order to clarify open questions. Thomas Produit
 (posted 2023-11-27 11:32:04.437) Hi,
Is there somewhere a graph explaining which pin to solder to which colored wire when hooking up for example the HPIR10X to the LEDD1B ?
Thanks in advance ! dpossin
 (posted 2023-11-27 05:11:09.0) Hello Thomas,
Thank you for your feedback. Since our high power emitters are thermal emitters there is no prefered pin configuration. Either way it will work. dpossin

 (posted 2023-11-11 09:18:12.32) Is there a graph of the angular output? Could I collimate with a lens? Is the angular output narrow enough to put a highpass thinfilm filter to narrow the spectrum? dpossin

 (posted 2022-10-19 09:16:35.833) can those be operated with a constant voltage supply? or do they require pulsed voltages.
Thanks
Sam dpossin
 (posted 2022-10-21 06:08:44.0) Dear Sam,
Thank you for your feedback. In general the efficiency of the IR emitters is the highest when driven with constant voltage sources. However it is also possible to pulse them using pulsed sources. When doing so the average light intensity depends on the pulse frequency and pulse width. The dependency can be seen in the datasheet. I am reaching out to you in order to give further adivce.
