At Chongfan Technology, each uncollimated, mounted LED is a single unit installed at the end of a heat sink, which features an SM1 (1.035”-40) internal thread 6 mm deep. LEDs equipped with a Ø1.20‑inch heat sink share the same outer diameter as the SM1 lens tube, ensuring compatibility with 30 mm cage systems. Some of our LEDs are mounted on larger heat sinks to accommodate the increased thermal load during operation. These heat sinks are enclosed in a Ø57.0 mm ventilated plastic housing, with four 4‑40 tapped holes on the front for integration. 30 mm cage system 。
Each LED is equipped with an EEPROM chip that stores LED-specific information, such as current limits, wavelength, and forward voltage. When controlled via Thorlabs’ DC2200, DC4100, or DC4104 LED drivers, this data can be used to enable intelligent safety features.
These installed LEDs exhibit excellent thermal stability, eliminating the issue of reduced light output caused by rising LED temperatures. For more details, please refer to the Stability tab.
Please note that the installed LED is not suitable for residential lighting applications.
The adjustable collimation adapters can each translate an Ø1‑inch (Ø25 mm) or Ø2‑inch (Ø50 mm) lens by up to 11 mm or 20 mm, respectively. Each adapter features an SM2 (2.035”‑40) internal thread, enabling easy integration of the LED with Thorlabs’ SM2‑threaded components, such as our… Ø2-inch lens sleeve These adapters are available with or without aspheric condenser lenses coated with anti-reflective film.
In addition, microscope collimation adapters incorporating anti-reflective coated aspheric lenses are also available. These adapters are compatible with the epi‑illumination ports of Leica DMI, Nikon Eclipse Ti, Olympus IX/BX, or Zeiss Axioskop microscopes. Thorlabs also offers Installed LED with a pre-installed microscope collimation adapter 。

Drive Options
Chongfan Technology offers five types of drivers that are compatible with most or all of these LEDs: LEDD1B、 UPLED 、DC40、DC2200、DC4100 and DC4104 (The last two models require DC4100-HUB ). UPLED, DC40, DC2200, DC4100, and DC4104 can read the current limit from the EEPROM chip of the connected LED and automatically adjust the maximum current setting, thereby protecting the LED.
Multiple LED light sources
Custom multi-LED light sources can utilize our pre‑installed LEDs and Thorlabs’ product architecture. These light sources can be configured for integration with Chongfan Technology’s multifunctional systems. SM1 Lens Tube System and 30 mm cage system 。
Chongfan Technology also offers integrated, user-configurable… Four-wavelength high-power LED light source 。
Deep ultraviolet LED, installed (233–340 nm)
Please note that our deep‑ultraviolet LEDs emit intense UV radiation during operation. Take appropriate protective measures: do not look directly at the UV light, and always wear UV‑protective eyewear. Safety goggles , to prevent eye injury. At the same time, avoid exposing your skin and other parts of your body to ultraviolet radiation.
UV LED, installed (365–405 nm)
Please note that our UV LEDs emit intense ultraviolet light during operation. Take appropriate protective measures: do not look directly at the UV light, and always wear UV‑protective eyewear. Safety goggles , to prevent eye injury. At the same time, avoid exposing your skin and other parts of your body to ultraviolet radiation.
Monochromatic visible-light (cold-light) LED, installed (415–565 nm)
Please note that the 415 nm (violet), 430 nm (violet), and 450 nm (violet) LEDs emit intense ultraviolet light during operation. Take appropriate protective measures: do not look directly at the UV light, and always wear UV‑protective eyewear. Safety goggles , to prevent eye injury. At the same time, avoid exposing your skin and other parts of your body to ultraviolet radiation.
Monochromatic visible light (warm light) LED, installed (590–727 nm)
Infrared LED, installed (780–1900 nm)
Mid-infrared LED, installed (3400–5200 nm)
Purple LED, installed (455 nm / 640 nm)
Our dual-peak wavelength LEDs are ideal for applications that require illumination in the red and blue regions of the spectrum, such as horticulture. The violet LED reaches its peak at 455 nm and 640 nm, respectively, to stimulate photosynthesis (see…). Line chart Compare the absorption peaks of photosynthetic pigments with the LED spectrum. LEDs are engineered to maintain a consistent red-to-blue light ratio throughout their service life, ensuring highly uniform lighting for plant growth.
White-light LED, installed (400–700 nm)
Our warm‑white, neutral‑white, and cool‑white LEDs feature broad spectra that span several hundred nanometers. The visual differences among these LEDs can be characterized by their correlated color temperature (CCT). CCT refers to the temperature at which a blackbody radiator would emit light with a color appearance similar to that of the LED. Typically, warm‑white LEDs produce spectra akin to tungsten‑filament sources, whereas cool‑white LEDs exhibit a stronger blue component. Neutral‑white LEDs, in contrast, deliver a more uniform spectral distribution across the visible range than either warm‑ or cool‑white LEDs. Cool‑white LEDs are particularly well suited for fluorescence microscopy or cameras equipped with white balance, as they display higher intensity across most wavelengths compared to warm‑white LEDs. Neutral‑white LEDs, meanwhile, are an ideal choice for horticultural applications.
Broadband LED, installed
The MBB1L3 broadband LED exhibits a relatively flat spectral emission over a broad wavelength range. Its 10 dB bandwidth spans from 470 nm to 850 nm. The MBB2L1 and MBB2LP1 broadband LEDs have spectra with peak wavelengths approximately at 770 nm, 860 nm, and 940 nm.
