Standard DOE

Digigram offers various kinds of standard Diffractive Optical Elements( DOEs).  These standard products can help product developers lower the barriers to entry, speed up DOE product development, and increase product added value. The standard DOE includes Random Dots, Circle Dots, Parallel Lines, Cross, ViewFinder, Squares, Concentric Pattern, Rectangle, Line, Regular dots etc.. Particularly, the pseudo-random infrared dots pattern is very suitable for structured light stereoscopic imaging or 3D sensing. If you need diffractive diffuser, diffractive beam splitter or diffractive beam shaping products, please contact us.


The DOE structures are replicated onto the substrate like PET or PMMA. The standard substrate is PET with standard size of 5 mm in diameter or 5mm x 5mm and 0.188mm in thickness. PMMA with 1mm in thickness is available for some products. Customized dimension is also possible. Please ask before ordering. If the applied wavelength is different from the designed one, the zero order will be stronger and the diffraction pattern will be distorted.

All the standard DOE can be sold with our EEL laser modules. Please refer to the list below for the available TO-CAN laser modules.

Products whose F= ∞ are suitable for collimated laser beam.
