FTO - FYRLYT Thermal Optics

Welcome to the debut of FYRLYT's first thermal rifle scope, the FTO-640 50. This is a natural progression from our spotlighting and thermal camera systems and also in response to working closely with our customer base. 


FYRLYT FTO-640 50 redefines the price point of performance & value

We predict many will believe we have made a pricing mistake as it being impossible to sell a thermal scope of such a high specification for this price. This is a 640x512 12μm sensor with a 50mmm f1.0 lens that atypically has been in the price range of $6000 AUD+.​
