Abstract: An optical design pattern/method was invented to control the total cost including the material and the manufacturing of IR imaging lenses. This optical design pattern/method comprises a molded lens and an aberration correction lens. This design pattern/method leads to cost-effective IR imaging lenses because the unit cost of the molded lens is low for a volume production and the unit cost of the aberration correction lens is low for its very small manufacturing. This optical design pattern/method comprises any imaging and spectral applications for any partial band of 1 to 14 micron, such as (but not limited to) SWIR, MWIR, and LWIR.

Abstract: Systems and methods for fluorescent microscopy are disclosed where fluorophores can be excited over an excitation band to emit light in a wide emission band. Simultaneous acquisition of multiple planes in the sample can be achieved using a modified form of confocal microscopy. In one implementation, an objective employs a lens having optics exhibiting a large degree of axial chromatic aberration, such that emissions from different axially spaced focal planes are encoded by wavelength. Advantageously, simultaneous acquisition of multiple focal planes encoded by color can be processed to obtain efficient and rapid three-dimensional imaging of a sample.

Abstract: The tri-axis close-loop feedback controlling module for electromagnetic lens driving device comprises a 6-pin Hall element. Two pins of the Hall element are coupled to an auto-focus module for providing a current to drive the auto-focus module to conduct auto-focusing operations along the Z-axis; while other four pins of the Hall element are coupled to a control unit. The control unit detects the X-Y axial positions of the auto-focus module relative to an OIS module and generates a control signal which is then sent to the Hall element. Therefore, the Hall element not only can provide its own feedback controlling function according to the Z-axial position of lens, but also can drive the auto-focus module based on the control signal corresponding to the X-Y axial positions of the auto-focus module, so as to achieve the goal of tri-axis close-loop feedback controlling for the electromagnetic lens driving device.
