An optical filter may include a set of optical filter layers disposed onto a substrate. The set of optical filter layers may include a first subset of optical filter layers comprising a first material with a first refractive index. The first material may comprise at least silicon and hydrogen. The set of optical filter layers may include a second subset of optical filter layers comprising a second material with a second refractive index. The second material is different from the first material and the second refractive index is less than the first refractive index. The set of optical filter layers may include a third subset of optical filter layers comprising a third material different from the first material and the second material.

Optical filter

A sensor window may include a substrate and a set of layers disposed onto the substrate. The set of layers may include a first subset of layers of a first refractive index and a second set of layers of a second refractive index different from the first refractive index. The set of layers may be associated with a threshold transmissivity in a sensing spectral range. The set of layers may be configured to a particular color in a visible spectral range and may be associated with a threshold opacity in the visible spectral range.

Optical filter comprising a sensor window to provide a transmissivity of less than 5% between approximately 400 nm and approximately 780 nm and a blocker to block transmission at less than approximately 1000 nm

Sensor window

A light shaping optic may include a substrate. The light shaping optic may include a structure disposed on the substrate, wherein the structure is configured to receive one or more input beams of light with a uniform intensity field and less than a threshold total intensity, and wherein the structure is configured to shape the one or more input beams of light to form one or more output beams of light with a non-uniform intensity field and less than the threshold total intensity.

Sensor window configured to pass near-infrared light and to reflect colors of light different from a color of a surface adjacent to the window

Sensor window comprising a plurality of sets of layers to reflect one or more colors of light that match a surface adjacent to the sensor window

Sensor window to provide different opacity and transmissivity at different spectral ranges

Sensor window with a set of layers configured to a particular color and associated with a threshold opacity in a visible spectral range wherein the color is a color-matched to a surface adjacent to the sensor window

An optical filter may include a substrate. The optical filter may include a set of alternating high refractive index layers and low refractive index layers disposed onto the substrate to polarization beam split incident light. The set of alternating high refractive index layers and low refractive index may layers may be disposed such that a first polarization of the incident light with a spectral range of less than approximately 800 nanometers (nm) is reflected by the optical filter and a second polarization of the incident light with a spectral range of greater than approximately 800 nm is passed through by the optical filter. The high refractive index layers may be hydrogenated silicon (Si:H). The low refractive index layers may be silicon dioxide (SiO).
