It stores the raw image data captured by the microscope's sensors, preserving the full dynamic range and fidelity of the acquired image. The .OIR format is proprietary to Olympus and is designed specifically for use with their FluoView software. This format ensures that the image data is maintained in its purest form, allowing for precise quantitative analysis and high-quality image processing. The .OIR format supports various imaging modes, including confocal, multiphoton, and time-lapse imaging, making it suitable for a wide range of biological applications. This file format is classified as Raster Image.
