Diffractive Optical Elements (DOE) -Evaluation Samples

Diffractive optical element (DOE) samples can be very helpful for industry and research in feasibility studies where a proof of concept has to be given. Ideas and theoretical concepts are abstract, thus difficult to understand, and therefore incorporate a higher investment risk. An optical set-up using standard DOEs can help to improve understanding, confirm the feasibility of a concept and therefore increase trust and readiness for investment support.

We provide a set of DOE evaluation samples that are intended for the purpose of feasibility studies or demonstration purposes. The DOE structures are replicated (embossed) into a thin film of UV-Acrylat, silicone or other polymers, depending on the desired wavelenght. The evaluation samples are delivered as acrylate on rectangular standard microscope slides (75mm x 25mm x 1 mm) used as substrate or on circular glass substrate (D=25 mm), mounted in black anodized aluminium mount with M4 thread (see picture above).
