The Yale Exoplanet Laboratory is under contract to design, build, and deliver a high-resolution (R = 60,000) echelle spectrograph for the Moletai Astronomical Observatory 1.65-meter telescope at the Vilnius University. We present a fiber-fed, white-pupil architecture that will operate from 400 to 880nm. The optomechanical design implements a modular approach for stability and ease of alignment that can be reproduced for other telescopes. It will utilize highperformance off-the-shelf optical components with a custom designed refractive camera for high throughput and good image quality.
