Successful integration of a cryocooler to an IR detector and an EO\IR system assembly depends on more than steady state input power or cooling capacity. Mission profiles, duty cycle, ambient conditions, system interfaces, and verification requirements jointly determine whether a cryocooler will meet performance, reliability, and lifetime targets.
A growing trend in cryogenically cooled infrared detectors is the shift toward higher operating temperatures, which relaxes cooling requirements while at the same time increasing the demand for smaller, lighter, and less expensive cryogenic solutions
The challenges of designing cooled IR detector systems have continued to grow in recent years, driving the development of more compact, high-resolution systems with improved performance. The demand for longer operational lifetimes, particularly for 24/7 applications and space missions has directly influenced cryocooler requirements.
This article reviews the development and performance of the Extended Linear (ELI) cryocooler models K589 and K591. The focus of this article is the SPRINT development cycle, which emphasizes simulation, risk reduction, and the creation of lean prototypes.
In line with growing trend of moving to HOT detectors, more than 8,250 Ricor’s SWaP-C Cryocoolers were successfully delivered to our customers for various projects in recent years. During this period, we launched R&D improvement programs to bring more capabilities from the current models.
In recent years, the trend of moving IR detectors to operate from standard 77K to the High Operating Temperature (HOT) of 150K, drives RICOR’s onward development focusing on SWaP-C, a new family of miniature cryocoolers, alongside continuing to make improvements to existing cryocooler models.
The modern needs of the electro optical market for small low-power and light-weight IR systems are impelling development of High Operating Temperature (HOT) IR detectors, requiring dedicated cryocoolers design.
The growing demand for EO applications that work around the clock 24hr/7days a week, such as in border surveillance systems, emphasizes the need for a highly reliable cryocooler having increased operational availability and optimized system’s Integrated Logistic Support (ILS). In order to meet this need, RICOR developed linear and rotary cryocoolers which achieved successfully this goal.
The modern needs of the electro-optical market for small low-power and light-weight IR systems are impelling research and development of High Operating Temperature (HOT) IR detectors, requiring development of dedicated “HOT” cryocoolers.
