Products

Composite Tailors develops and manufactures CFRP space optical telescopes that can be a "Game Changer of Space Optics."
By replacing all glass and low-thermal-expansion metal components of conventional space telescopes with CFRP, we achieve dramatic improvements in both weight and productivity.

Features of CFRP Space Optical Telescopes

Ultra-Lightweight

Achieves a 1/2 to 1/3 weight reduction compared to conventional glass-mirror telescopes. This expands design possibilities for small satellites with strict mass budgets.

Quick Delivery & Mass Production

Mirror fabrication that previously required months with glass can now be completed in days, enabling significantly shorter lead times and high-volume production.

Low CTE & Athermal Optics

Achieves a CTE on the order of 10^-7 /K. This enables athermal optical designs because the mirror and structure are all made of CFRP.

Business Development of CFRP Space Optical Telescopes

CFRP telescopes serve as mission payloads for low-Earth-orbit optical Earth observation constellations, contributing to land management, disaster monitoring, and environmental conservation.
As optical systems for free-space optical communication terminals, they are also expected to play a broad role — from inter-satellite links and HAPS to Earth-to-lunar communication.
