A glueless optical device includes a housing having a first optical portal and a second optical portal opposite the first optical portal. A first optical component is within the housing adjacent to the first optical portal, and a second optical component is within the housing adjacent to the second optical portal. A central optical component is positioned within the housing between the first optical component and the second optical component. A first holder is configured to mount the first optical component to the housing via a first plate spring, and a second holder is configured to mount the second optical component to the housing via a second plate spring. A construct having a coil spring at least partially wrapped around a cylindrical crystal is configured to pass through a bore hole in the central optical component and mount the central optical component between the first holder and the second holder.
