Abstract
The present disclosure relates to optical systems for fluorescence-based imaging. An example optical system includes an image sensor. The image sensor is sensitive to at least a first wavelength of light and a second wavelength of light. The optical system also includes a light guiding layer optically coupled to the image sensor and a light source positioned to emit light into a side surface of the light guiding layer. The emitted light includes light at the first wavelength and the emitted light is transmitted in an in-plane direction in the light guiding layer. The optical system further includes a thin film filter and an output coupler optically coupled to the light guiding layer. At least a portion of the emitted light transmitted in an in-plane direction in the light guiding layer is coupled out of the light guiding layer in an out-of-plane direction via the output coupler.
