Next are "telephoto" lenses reaching up to 300mm, and finally "super telephoto" lenses covering focal lengths of 300mm and greater.a total of five groups.

For example, if a 35 mm lens casts a 1.2 cm image of a person, that image will remain 1.2 cm high regardless of your camera's sensor format. However, on a Micro ...

Opticalmeaningin Hindi

In this Letter, a low-cost refractive convex microlens array device based on infrared a polymer is fabricated by a nanoimprinting technique. The device integrates more than 4000 microlenslets within a footprint of 10  mm×10  mm. The surface quality, spectral transmittance, imaging resolution, and surface damage threshold of the device have been fully characterized. The IR imaging and parallel laser inscription experiments confirm the remarkable optical performance of the fabricated device. Owing to the merits of high optical quality, low fluence lose, and simple fabrication, this device is promising in cutting-edge IR applications, such as IR imaging, laser fabrication, and so on.
