Infrared Metrology & Calibration Lab Solutions: Radiance Traceability and Temperature Curve Calibration

The core of an infrared metrology and calibration laboratory lies in establishing stable and traceable radiation references. Yingshengyuan's High-Precision Area Blackbody, High-Temperature Area Blackbody, and High-Precision Low-Temperature Blackbody cover a wide temperature range from low to high. Combined with the Comprehensive Infrared Thermal Imager Test System, they form a complete technical loop from radiation source to full-system testing. This solution helps users select the appropriate equipment based on application scenarios, ensuring accuracy and repeatability of temperature curve calibration.

01

Calibration Chain Overview

Radiance traceability is typically divided into three levels: Primary Standard Blackbody (fixed-point blackbody) as the national reference, Secondary Standard Blackbody (e.g., Yingshengyuan high-precision area blackbody) for laboratory transfer, and Working Blackbody (high/low temperature blackbody) directly serving production lines or field testing. Yingshengyuan's product line covers the latter two levels, enabling users to flexibly select based on the target temperature range and aperture of the device under test.
02

High-Precision Area Blackbody – Ambient Reference and Uniformity Correction

The IBBE Series High-Precision Area Blackbody offers multiple radiation surface sizes (e.g., 100 mm, 200 mm, 300 mm), suitable for FPA process testing, thermal imager key parameter evaluation when used with infrared targets and collimators, and uniformity correction for infrared imaging systems. This series is the preferred reference source for the ambient temperature range in laboratories.
Recommended selection: choose the corresponding radiation surface size based on the detector or thermal imager target size. For details, refer to IBBE-A Series product page.
03

High-Temperature Area Blackbody – High-Temperature Temperature Curve Calibration

The IBBE-H Series High-Temperature Area Blackbody is specifically designed for high-temperature temperature curve calibration of infrared imaging systems, featuring high stability and uniformity. Models cover 100H, 150H, 200H, 300H for different radiation surface sizes. Suitable for thermal imager test point calibration and uniformity correction.
Selection tip: high-temperature calibration requires matching the radiation surface size with the tested aperture. See IBBE-H Series product page for specific parameters.
04

High-Precision Low-Temperature Blackbody – Low-Temperature Radiometric Calibration

The IBBE-L Series High-Precision Low-Temperature Blackbody meets low-temperature infrared radiometric calibration and low-temperature target simulation needs. It features a fanless design to reduce convective disturbance and built-in low-temperature anti-condensation technology to ensure accurate radiation characteristics under low background. Ideal for low-temperature infrared detector calibration and environmental simulation testing.
Selection advice: choose based on the minimum target temperature and cavity size. For details, see IBBE-L Series product page.
05

Comprehensive Test System – Full-System Imaging Parameter Evaluation

The IRCM Series Comprehensive Infrared Thermal Imager Test System integrates testing capabilities for NETD, MRTD, MDTD, MTF, optical axis alignment, distortion, and radiometric response. It is specifically developed for MWIR, LWIR, and SWIR camera systems. When used with the above blackbody sources, it enables comprehensive evaluation from single-point temperature calibration to spatial frequency response.

Recommendations for Building a Calibration Traceability System

It is recommended that laboratories build calibration capabilities following this process:
1. Use a High-Precision Area Blackbody as the daily radiation transfer standard, and periodically calibrate it at a higher-level metrology institution (refer to Blackbody Calibration Traceability Topic).
2. Configure a High-Temperature Blackbody based on the highest test temperature for high-temperature calibration of thermal imagers.
3. If low-temperature detector calibration is involved, introduce a Low-Temperature Blackbody and ensure background radiation control.
4. Deploy a Comprehensive Test System for one-key imaging parameter testing.

FAQ

How is a blackbody radiation source traceable?
It is recommended to send Yingshengyuan blackbodies to a qualified third-party metrology institution periodically for comparison calibration using fixed-point blackbodies or standard radiation thermometers. For details, see Blackbody Calibration Traceability Topic.
How to choose different sizes of blackbody radiation surfaces?
Selection is primarily based on the optical aperture and test distance of the device under test. Typically, the blackbody radiation surface should fully cover the field of view under test. Yingshengyuan offers sizes from 100 mm to 300 mm. For specific selection, consult sales representative.
Can high-temperature and low-temperature blackbodies be used together?
Yes. The high-temperature blackbody handles high-temperature calibration, while the low-temperature blackbody handles low-temperature calibration. Together they cover the full temperature curve. Laboratories typically need two independently controlled blackbodies.
Does the comprehensive test system require a separate blackbody?
The IRCM series has an integrated radiation source interface, but users can also connect an external Yingshengyuan blackbody for multi-temperature point calibration. The system supports automatic temperature point switching for multi-point radiometric response testing.
