K508N Highly Reliable Integral Stirling 1/2W MicroCooler

The K508N is a new member of RICOR‘s microcoolers family. This model was developed as a high reliability K508 derivative with a goal of increasing cooler reliability above 20,000 operating hours. K508N is ideal for systems‘ life cycle cost improvement especially for applications operating 24/7 in border surveillance IR systems. The K508N is fully interchangeable with the standard K508 cryocooler and designed to be integrated with all types of K508 cold fingers/DDAs.

The cooler is designed to withstand harsh environmental conditions and excels in low vibration export and low acoustic noise level.
