In order to clearly see specimens, a microscope will need to light or illuminate them. The most common type of illumination for biological microscopes is bottom illumination, or a light that shines up from below the stage. Bottom illuminators are most commonly bright-field illuminators. In this type of system, a beam of highly directional and intense light is projected upwards. Light is aimed from below the stage through a condenser lens, through the specimen and then through the optics of the microscope to your eye. Most of the time, this is the best way to see the most detail in a slide or similarly prepared or mounted specimen.If the object is small, glare from the illuminator can be a problem. To avoid this, dark-field illumination can be used to increase visibility. This system uses an opaque disk to block the central light from the condenser, only allowing marginal rays to illuminate the specimen. The result is a bright image against a dark background.Since little light actually falls on the specimen, dark-field illumination shows less detail overall than bright-field illumination. It should only be used in circumstances where bright-field illumination overwhelms your view of any of the specimen’s details.

Unlimited possibilities also apply to the technical lighting features: light colours, colour rendition, opal diffusers and microprismatic optics for glare-free use in offices are freely configurable. Direct and indirect light can be switched separately, and a wide variety of colours and surfaces promote perfect architectural adaptation.

For years, architecture was characterised by cubism - functionalism and clear lines were in the foreground. Through new building technologies, the forms of architecture became increasingly organic and expressive, characterised by flowing lines and new combinations. This architectural development in combination with LED technology, which makes almost any form technically feasible, enabled us to think much more freely in terms of design and forms. This was the birth of the Liquid Line. Lightnet was the first manufacturer on the market with a flexible light line for flowing shapes and to this day we are the only supplier who can implement all radii horizontally and vertically.
