Abstract
Disclosed is an LED arrangement for a microscopy instrument (200 FIG. 2) comprising a light emitting area (112), and a part-spherical solid and light transmissive cap (120), in light communication with the light emitting area, the cap having a hemispherical surface (126) including a portion (124) at which light from the light emitting area is reflected and a portion (128) at which light from the emitter can exit the cap, in order to provide a usable light cone L which includes light recycled from the more divergent emitted light, and is thereby more intense.
