Abstract
An optical filter may include a monolithic substrate. The optical filter may include a first component filter disposed onto a first region of the monolithic substrate. The first component filter may be a near infrared (NIR) bandpass filter. The optical filter may include a second component filter disposed onto a second region of the monolithic substrate. The second component filter may include a red-green-blue (RGB) bandpass filter. A separation between the first component filter and the second component filter may be less than approximately 50 micrometers (μm).
