摘要： A digital diagnostic system with interchangeable lenses includes a host and at least one optical lens module, wherein the host without any optical lens having curved surface includes a focus adjustment module which drives an image capture module to linearly move. Therefore, the optical system of the optical lens module can be designed independently, and no need to include focus adjustment mechanism, so that the optical design of the optical lens module can be greatly simplified, and the system allows a greater mechanism tolerance, thereby reducing manufacturing difficulty and manufacturing cost.

摘要： An image system adapted to a projection display apparatus includes a first lens group having a negative refractive power, a second lens group having a positive refractive power, an aspheric reflector, and a curved reflector. The second lens group includes an aspheric lens which is the nearest to the light valve in the second lens group. A material of the aspheric lens includes glass, the thermal-optical coefficient of the glass is between 1.0×10−6/K and 12.5×10−6/K, and the refractive index of the glass is between 1.482 and 1.847. The aspheric reflector is disposed front of the first lens group for reflecting the image beam passing through the first lens group and second lens group. The curved reflector is disposed above the first lens group for reflecting the image beam reflected by the aspheric reflector onto the screen. The image system has a good imaging quality.
