Compound eye of a fly, SEM Featured Print

Compound eye of a fly, SEM

Compound eye. Coloured scanning electron micrograph (SEM) of the surface of a compound eye from a fruit fly (Drosophila busckii). The eye consists of many rounded lenses known as ommatidia. Each ommatidium is a simple eye that sends a signal to the fly's brain. All the signals are combined by the brain to form a mosaic view of the world. The image seen is not very sharp but good at detecting movements. Between the lenses are hair-like structures called interommatidial bristles. Magnification: x2500 when printed at 10 centimetres wide

Reflaction and Telescope Optics Featured Print

Reflaction and Telescope Optics

Plate from 18th century encyclopedia showing diagrams of telescope optics, and light raypaths through prisms and lenses to the eye. An eyepiece, or ocular lens, is a type of lens that is attached to a variety of optical devices such as telescopes and microscopes. It is so named because it is usually the lens that is closest to the eye when someone looks through the device. The objective lens or mirror collects light and brings it to focus creating an image. The eyepiece is placed near the focal point of the objective to magnify this image. The amount of magnification depends on the focal length of the eyepiece. Two drawings illustrate lightpaths through reflecting telescopes, one showing the rays reflected by an angled flat mirror through 90 degrees to an eyepiece, the other reflected back through a hole in the primary mirror
