Ophthalmic endoscopes allow examination of intraocular structures when traditional surgical microscopic visualization is limited or impossible. Periodic evaluation of the optical precision of these instruments is essential to ensure optimal intraoperative performance. A test card has been developed to aid in the calibration of ophthalmic endoscopes. Its 5 test targets assess white balance and fiberoptic bundle integrity, focus and resolution, orientation, color fidelity, and angle of view.
当传统手术显微镜可视化受限或无法进行时，眼科内窥镜可用于检查眼内结构。定期评估这些仪器的光学精度对于确保最佳术中性能至关重要。现已开发出一种测试卡，以辅助眼科内窥镜的校准。其5个测试目标可评估白平衡和光纤束完整性、聚焦和分辨率、方向、色彩保真度以及视角。
