General Optics
DOE Flat Lenses and Lenslet Arrays
Focus or collimate light without the limitations and aberrations of refractive optics, using lenses that can perform multiple phase transformations in a single surface.
These versatile optics are mass-produced using digital surface relief (lithographic) patterning. They are ideal for optical engines and pattern generators in 3D sensing (consumer devices, autonomous vehicles). Also perfect as micro-optic lenses and arrays for transceivers.
Lenses and Lenslet Arrays – Customizable Performance
Use these lightweight lenses even in harsh conditions, including high optical power and temperatures up to 500 °C. All physical dimensions (WxH) are custom-specified.
