Industry-specific solutions are the optimal solutions for starting quality tests tailored to the needs and requests of users.
Most medical imaging applications are designed to capture images at a microscopic (or small) scale. Therefore, the test charts must also be small. To uniformly illuminate the final image with the same light source, we recommend the CAL4 integrating sphere with a diameter of 30 cm, which comes with four types of connection adapters for various endoscope light sources. (Note: The CAL4 does not come equipped with light sources such as iQ-LED.) The opening of this integrating sphere features a 50x50 mm output window with a slot for a D35 size chart. For resolution measurement, a D35 size Siemens star TE253 9x (compliant with ISO standard 12233:2014) is recommended. For measuring OECF, dynamic range, noise, etc., a D35 size TE240 chart with 24 gray patches (compliant with ISO 21550) is recommended. For color evaluation, the transmissive Calibrite ColorChecker TE188 (D35 size) is recommended, and for visual assessment, the U.S. Air Force resolution chart TE250 for 35mm film (D35 size) is recommended.
