Plastic diffractive optical elements can save costs

If diffractive optical elements are used at low and medium laser power, it is not always necessary to use expensive fused silica elements because plastic elements may be sufficient. Holo/OR offers plastic DOEs in different materials: polycarbonate, PMMA, Zeonex, and Zoner, produced in large quantities using an injection moulding process.

Plastic DOEs are advantageous in systems that are mass produced. As most customers will require bespoke optics, Holo/OR offers inexpensive tooling and low production costs.

Do you already have a DOE design manufactured on a fused silica element?  As long as it is physically possible, this design can be adapted to a plastic DOE design.

Multi-spot DOEs and homogenisers are currently available as standard elements for wavelengths of 850nm and 532nm.

For evaluation purposes, Holo/OR uses software developed in house, to obtain a data file for the DOE with the quotation. This file can then be integrated into your own software (Zemax or Lighttrans) for further simulations.
