Diffractive Optical Element, Diffractive Optics, Diffractive Lens

Digigram offers various kinds of standard Diffractive Optical Elements( DOEs). These standard DOE products 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 laser random dot pattern is very suitable for structured light module/ projector. If you need diffractive diffuser, diffractive optics, diffractive beam splitter or laser beam shaping optics, beam shaper, diffractive lens, doe laser, diffractive grating please feel free to 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.

We also offer Laser pattern generator products like line or circle Laser module. All the standard DOE can be integrated 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.
