The level of optical power (i.e. magnification) has been selected with attention in order to provide the best whole of optical performance and usability. Moreover, magnification is not an important parameter for digital optics (and microscopy); the most important parameters are resolution, i.e. the ability to distinguish tiny features, and field of view, i.e. the imaged area without scanning your device on the sample. With proper lighting BLIPS Micro can achieve a resolution <4microns, and its field of view is of about 5mm × 3mm. For BLIPS Macro they are about the double.
- Higher magnification needs very short deep of focus, significantly smaller field of view and very short working distance.
- Shorter deep of focus makes very difficult to get images in focus using hand-held devices
- Smaller field of view makes very difficult to find the sample you want to observe behind the smartphone.
- Very short working distance do not allow to film or shoot nature subjects like insects, to look inside flowers, or to check inside small 3D structures.
Higher optical magnification can be achieved with different systems where sample and optics are rigidly kept at a defined distance, but the fields of applications are partially different with respect to the targets of BLIPS
