IRLabs provides comprehensive IR detector solutions including custom bolometer systems, advanced cooled optics, and complete infrared detection assemblies. Our IR detector options span from research-grade cryogenic bolometer systems to specialized infrared detection configurations for demanding scientific and industrial applications.

Our bolometer and IR detector expertise encompasses thermal detection across the complete infrared spectrum, from near-infrared through far-infrared wavelengths. Whether you require cryogenic bolometer systems for astronomy applications, or precision IR detector assemblies for spectroscopy, our team delivers custom solutions optimized for your specific detection requirements.

If your application requires a customized bolometer system, our engineering team will collaborate with you to identify the most suitable bolometer for your specific performance goals. We can tailor the system’s optical elements, recommend electronic readout and amplification options, and provide a cryostat designed to house and operate these components within your budget and operational requirements.

Since our founding, we have designed, produced, and integrated thousands of IR detection and cryogenic systems for clients worldwide, including leading research institutions, aerospace companies, and semiconductor manufacturers. Our bolometer and IR detector systems support critical applications in astronomical observation, materials research, thermal imaging, gas sensing, and semiconductor failure analysis.

From single-pixel bolometer detectors to large-format IR detector arrays, IRLabs combines decades of thermal detection expertise with cutting-edge fabrication capabilities to deliver bolometer solutions that meet the most demanding infrared detection challenges.

System customization is typically in these subcomponent groups:

  • Custom Research Cryostats
    Dewars and refrigerators designed for dual sensors, proper operating temperature, optical requirements, hold times, and specific materials.

  • Cooled Optics
    Design and construction of transmitting and reflecting systems including windows, filters, beam-splitters, polarizers, Lyot stops, baffles, lenses and mirrors.

  • Electro-Mechanical Devices
    A wide variety of options are available including multi-position filter wheels/slides, stepper motor drives, cooled shutters, and temperature controlled stages.

  • Electronics
    Custom and standard configurations consisting of cooled “JFET” front ends, low noise preamps, and data acquisition systems.

  • Testing
    All detectors are fully tested and characterized. Complete test results accompany each system.

  • Design Assistance
    Technical consultation and design services are always available. In many cases these services are offered free of charge.

FAQs

What is a vacuum dewar?2025-10-28T08:28:00-07:00

A vacuum dewar is a specialized cryogenic storage vessel engineered with a high vacuum space (typically 10⁻5 Torr or lower) between double walls to minimize heat transfer and maintain extremely low temperatures. When configured for liquid helium applications, a vacuum dewar enables temperatures as low as 1.6K, making it essential for superconducting research, quantum experiments, and advanced IR detector cooling. The vacuum dewar’s superior insulation properties, enhanced by radiation shields and aerospace-grade materials like 6061 aluminum and high-purity copper, allow liquid helium to maintain its ultra-low temperature with minimal boil-off rates.

Unlike standard liquid nitrogen dewars that operate at 77K, liquid helium vacuum dewars require specialized construction to handle the extreme temperature differential and preserve the costly liquid helium for extended experimental periods. IRLabs designs custom vacuum dewar systems that integrate liquid helium cooling with precision temperature control, making them ideal for applications requiring the ultimate in cryogenic performance.
