CX TECH TEO Series: Annular Thermoelectric Cooler TEC1-11708 – Ring-Shaped Precision Cooling with Central Aperture
CX TECH’s TEO Series annular (ring-shaped) thermoelectric coolers are engineered for applications where a central aperture is essential—allowing light beams, probes, sensors, or mechanical components to pass through without obstruction while providing powerful and reliable cooling. The TEC1-11708 exemplifies this innovative design, delivering excellent performance in demanding optical and precision environments.
Key Performance Highlights

- At Th=50°C: ΔTmax ≥72°C, Qmax 69.01W
- ACR 1.51Ω ±10% (27°C) / 1.76Ω ±10% (50°C)
- MTTF > 200,000 hours, alumina ceramic substrates, SnBi 138°C solder, 703 silicone perimeter sealing
Expanded Application Scenarios
- High-Power Laser Diodes & Fiber Lasers Ideal for DPSS lasers, fiber-coupled diode modules, industrial marking/cutting lasers, and LiDAR transmitters where the optical beam must pass directly through the center of the cooler. → Recommended: Use in wavelength-stabilized systems to maintain beam quality and extend diode lifetime under continuous operation.
- Optical Communication Modules Perfect for cooling butterfly packages, TO-can lasers, coaxial transmitters, and high-speed transceiver arrays in 5G/6G base stations and data center interconnects. → Recommended: The central hole prevents any shadowing of the optical axis, improving coupling efficiency and reducing thermal wavelength drift.
- Infrared & Thermal Imaging Detectors Widely used in cooled IR cameras, focal plane arrays (InSb, MCT, microbolometer), gas imaging spectrometers, and defense/surveillance thermal sights. → Recommended: Maintains low NETD and high sensitivity in long-wave and mid-wave infrared systems.
- Medical & Aesthetic Laser Equipment Excellent for laser hair removal, skin rejuvenation, tattoo removal, vascular lesion treatment, ophthalmic lasers, and fractional CO2 systems. → Recommended: Enables safe, precise beam delivery while keeping the handpiece or applicator cool during extended treatments.
- Scientific & Research Sensors Suited for avalanche photodiodes (APD), photomultiplier tubes (PMT), scientific CCD/CMOS cameras, Raman spectroscopy detectors, and fluorescence lifetime imaging systems. → Recommended: Reduces dark current and thermal noise in ultra-low-light detection setups.
- PCR Thermal Cyclers & Lab Instruments Applied in compact benchtop PCR machines, real-time qPCR modules, and point-of-care diagnostic thermal blocks. → Recommended: Supports rapid ramping rates for faster cycle times in portable or high-throughput lab equipment.
- Emerging & Niche Uses
- Center-hole mounting for rotary optical encoders and precision goniometers
- Cooling of through-hole sensors in automotive LiDAR and ADAS modules
- Integration in endoscopic laser delivery systems and surgical robotics
- Cooling of ring-mounted MEMS mirrors in projection and beam-steering devices
