These are examples of the kinds of optical designs I typically create in Zemax:
Macro Attachment Lenses
This video was filmed using a set of cinematic macro lenses I designed for Lindsey Optics in 2017.
Double Telecentric Zoom
I designed this 2-4x aspheric zoom to have a fixed total track. It’s telecentric in both object and image space.
Pancake Lens for VR
I was inspired to create this polarization-based “pancake lens” design by a 2018 Oculus VR patent. Light from a display is converted from p to circular polarization by a quarter waveplate oriented 45 deg relative to the polarization axis. The light is then transmitted through a partially reflective, curved mirror. A second quarter waveplate converts it from circular to s polarization, which is reflected by a curved polarizer. The light then passes through the waveplate two more times, rotating the polarization to p, which is then transmitted to the eye. The folded design allows for a longer focal length in a smaller package.
Semi-transparent Mangin Mirror Lens
I designed this F/7 compact lens with external pupil to be diffraction-limited over a 20-deg FOV in the visible. It has two “Mangin” type lenses with an air space in between. Straylight could potentially be reduced with polarizers, as in the pancake lens.
Off-axis Reflective Imager
This F/5 off-axis reflective imager is nearly diffraction-limited over a 10-deg FOV. I used two conic sections and one biconic section for the mirrors.
Acrylic Freeform Version of Off-axis Reflective Imager
Same design as above, reoptimized as a solid acrylic optic. It’s still nearly diffraction-limited for a single wavelength, but as expected, this version has chromatic aberrations.
LED Array Collimator
I designed this LED collimator for an Osram SoleriQ P9 LED array. It’s solid plastic with a cylindrical recess where the LED is inserted. The rays are either focused by a small lens at the end of the recess or totally internally reflected by the outer boundary.
Lenslet Array Beam Combiner
I designed this hexagonal lenslet array and lens to combine an array of sources.
