PlaneWave Instruments designs and manufactures high-end telescopes intended to deliver pinpoint star images across large fields. Its CDK design aims to provide a flat, coma-free, and astigmatism-free field, addressing off-axis aberrations that limit performance in many telescope systems. The instruments are suitable for both visual observation and CCD imaging, emphasizing consistent optical quality across the field. The company is based in Adrian, Michigan, after relocating its main campus from Los Angeles in 2018, and operates within the Appliances, Electrical, and Electronics Manufacturing sector.

Customers include astronomers and imaging specialists who require precise optics for wide-field views. In 2025, PlaneWave merged with OurSky to form Observable Space, a broader software and hardware company that extends its reach beyond standalone telescopes.
