There is no opposite of optical. If there was it would something like "that which does not deal with optics," which is more like an opposing definition, but still an indefinite opposite as there are a lot of things that do not deal with optics (disregarding things that can be seen or cases in which "optical" refers to a type of machine, technology, etc).

Optical illusion.
A mirage is an optical phenomenon that creates the illusion of water. I can't imagine an opposite of seeing an illusion.
Optical inversion refers to a phenomenon where a chiral molecule rotates plane-polarized light in the opposite direction from its enantiomer. This occurs due to the molecular structure causing different interactions with polarized light. It is a key concept in understanding the behavior of chiral compounds in optical activity.
The opposite of binoculars would be a monocular, which is a single lens optical instrument used for viewing distant objects with one eye.
The visual and optical opposite of transparent is "opaque."Metaphorically, the description of motives as transparentwould have the opposites unclear or hidden.
This phenomenon, known as the wagon-wheel effect, occurs when the frame rate of a camera is synchronized with the rotational speed of the wheel. It creates an optical illusion where the wheel appears to rotate in the opposite direction due to aliasing effects.
Optical isolation refers to a technique used to prevent unwanted feedback or interference in optical systems, ensuring that light travels in one direction without reflection back into the source. This is commonly achieved using optical isolators or isolator components, which allow light to pass in a designated direction while blocking any light that attempts to travel in the opposite direction. Optical isolation is crucial in applications like laser systems, where back reflections can destabilize the laser operation.
Generally speaking, the opposite of brown is blue or bluish-grey. The complements of brown differ greatly based on the exact color as it is common for browns to be tinted with red, yellow and greens. The following colors are optical complements of browns.
Definition: Inverted Optics (IO):This Optics is called "Inverted", Not because the Light would travel in the opposite direction, but because some important optical Components have exchanged/inverted there place on the Optical-Workbench, compared to the "Standard" Optics. This Definition holds not only for Spectrometers, it holds also for Microscopes, where Observer (Your Eye) and the Light-Source (Lamp) have inverted there place on the Optical-Workbench, and so You are viewing the Bottom of the Object and not its Top anymore (You have always to take care for that!).This means, that in case for Microscopes also the Light is traveling in the opposite Direction.
