PlaneWave IRDK24 F/6.5 OTA

PlaneWave IRDK24 – 24-Inch Infrared-Optimized Dall-Kirkham Telescope System

Engineered for peak performance in the infrared spectrum, the IRDK24 is a precision observatory-class instrument tailored for advanced research and imaging.

The PlaneWave IRDK24 telescope system is built around a 24-inch (610mm) aperture and gold-coated mirrors that are optimized for infrared reflectivity. With a rigid carbon fiber OTA and fused silica optics, the IRDK24 delivers exceptional thermal stability and optical clarity—making it a premier choice for infrared astronomy and scientific applications requiring high-contrast data in non-visible wavelengths.
