It is mainly used for EMVA1288 related parameter correction such as flat field correction, linearity correction, dark noise correction, dynamic range correction, etc. of various cameras. It is widely used in many industries:
Solid-state flat-field tunable light source, color temperature adjustable from 2800K to 7500K (Spectra-CT)
In recent years, with the rapid development of machine vision systems, more and more production lines use industrial camera-based systems for rapid measurement, guidance, detection and target recognition. One of the main applications is flat panel display inspection systems, especially after the large-scale use of OLED panels in consumer electronics, higher requirements have been placed on machine vision systems. A high-precision machine vision system requires high-performance light sources for correction.
Labsphere Spectra-CT LED integrating sphere uniform light source provides an ultra-uniform, high dynamic range area light source with finely adjustable brightness/color temperature. The integrating sphere light source is based on Labsphere's more than 40 years of optical system development experience, self-developed high reflectivity diffuse reflection materials, and ingenious integrating sphere structure design. It is an ideal solution for R&D testing, quality inspection and production testing in the industry. Program.
The Spectra-CT integrating sphere based uniform light source utilizes warm white and cool white LEDs controlled by a high precision programmable DC power supply. Built-in active cooling system maintains stable output in the brightness range up to 50,000 cd/m2.
The system software is simple and easy to operate, which can be conveniently set, adjusted, and output different levels of brightness and color temperature, and can monitor various indicators of the system in real time. For advanced applications, such as multi-system integration, software APIs can be used.
The Spectra-CT LED integrating sphere uniform light source provides the high-performance light source required to meet the international camera performance test standard EMVA-1288, and can perform flat field correction, linearity correction, dark noise evaluation, etc. for industrial cameras.
