Relay Optic
Relay optics are optical systems used to transfer an image or a light beam from one position to another without changing the optical properties of the original image. It typically consists of one or more lenses or mirrors that are carefully arranged to create such a "relay" system.

Telecentric Lens
Bi-Telecentric Lens In a bi-telecentric lens the chief rays of both the object and the image space are parallel. This results in constant magnification independant of the object or image distance.

Maskless Lithography
Maskless lithography is a type of lithography common in printed circuit boards (PCB) and other precision manufacturing applications. It uses DLP® technology to project UV or LED light onto photoresist films and other photosensitive materials, including silicon wafers. Unlike traditional lithography, however, maskless projects the light directly onto the material without the need for a custom mask layer to selectively limit and disperse the light appropriately.

Biofabrication
Biofabrication is the production of biological products. These products can be made from materials such as biomaterials, matrices, and living cells. Biofabrication offers the opportunity to reconstruct the structural and functional complexity of human tissues. This rapidly developing technology has been encouraged by the development of Additive Manufacturing Technologies.
