STANDARD DOE (GLASS)
Standard Diffractive optical element 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.
The DOE structures are replicated (embossed) into a thin film of UV-Acrylat, silicone or other polymers, depending on the desired wavelength. We offer this line of Standard Diffractive Optics in 2 different substrate configurations:
Acrylate on circular glass substrate Ø 18 mm
Acrylate on circular glass substrate Ø 18 mm, mounted in black anodized Ø 25mm aluminium mount with M4 thread
Please note: The images of the patterns in the tables below are schematic drawings. In a real setup, higher diffraction orders can be visible, and the undiffracted order can appear as a bright spot in the center.
