OPTICAL DESIGN & SIMULATION

We develop powerful ray-optical and wave-optical designs to reach your most demanding specifications.

Utilizing all modes of light manipulation.
We design complex systems leveraging refraction. diffraction, reflection, absorption, polarization, or any combination of them in hybrid optical systems.

Using the appropriate methods for the problem.
• Sequential or non-sequential raytracing
• Angular spectrum propagation
• Scalar 3D wave propagation
• Rigorous simulation (FDTD, FEM)

Examples:
• TIR concentrator
• Tilted view endoscope lens
• Flat lens / metalens
• Reflective-refractive hybrid lens
• 3D full wave simulation through lens doublet
• Fresnel-TIR hybrid lens

PTX90-f42 Micro Camera Objective

The PTX90-f42 is a micro camera objective with a 90° FOV that is meant to be glued directly onto the cover glass of an imaging sensor. It's encased in a metal casing for mechanical and optical protection and sealed against the environment.
