The IRDK14 from PlaneWave Instruments is a precisely engineered optical system designed for high performance in infrared wavelengths. It is an excellent tool for advanced astronomical research and remote sensing applications, offering superior performance for infrared imaging.
IRDK14’s Key Features
Large Aperture and Optimized Focal Ratio
The IRDK14 features a 356 mm aperture and an f/7.2 focal ratio, enhancing its capacity to gather infrared light effectively. This setup is ideal for detailed infrared observations and long-exposure imaging, providing exceptional light-gathering capabilities.
Specialized Optical Design for Infrared
The Dall-Kirkham optical design of the IRDK14 is optimized for infrared wavelengths. There are no refractive lenses, only reflective fused silica mirrors. The reflective coatings are a protected gold with better than 98% reflectivity from .65 microns (650nm) to 5 microns (5000nm), making it well-suited for infrared astronomy or LIDAR applications. UV-optimized coatings can also be provided, and potential customers are encouraged to contact our technical sales team to discuss UV optimization.
Robust Mechanical Structure
Constructed using carbon fiber, the optical tube of the IRDK14 offers durability and stability with minimal thermal expansion. This design ensures consistent performance under various environmental conditions, making it suitable for intensive scientific applications.
Advanced Thermal Management
The IRDK14 includes cooling fans and a system prepared for Delta-T applications, promoting rapid thermal equilibrium. This feature is critical for minimizing air turbulence within the tube, thus reducing potential image distortion and enhancing overall imaging quality.
Integrated Dew Control
Infrared observations are prone to condensation, but the IRDK14 tackles this with advanced dew prevention technology. Heater pads, controlled via PlaneWave’s software, ensure the optical surfaces stay clear from dew, maintaining consistent and clear imaging performance.
Application-Specific Benefits
Infrared Astronomy
The IRDK14 excels in infrared astronomy, where its significant aperture and infrared-optimized optics allow for precise observation of celestial objects in infrared light. This capability is essential for studying astrophysical phenomena invisible to the naked eye or standard optical wavelengths.
Advanced Research and LIDAR Applications
With its specialized design and infrared optimization, the IRDK14 is a robust platform for advanced scientific research, including LIDAR and other remote sensing applications.
