IRDK24 f/6.5

The IRDK24 features a 610 mm aperture with an f/6.5 focal ratio, ideal for detailed infrared observations and long-exposure imaging with superb light-gathering capabilities. This Dall-Kirkham optical design uses only reflective components with no refractive lenses, with coatings optimized to transmit in infrared wavelengths. Constructed with a carbon fiber optical tube, it offers durability and stability with minimal thermal expansion, ensuring consistent performance across temperature variations suitable for intensive scientific applications. Protected gold reflective coatings are optimized for infrared astronomy and LIDAR, while integrated cooling fans enable rapid thermal equilibrium to minimize air turbulence and image distortion.
