Product Overview

Description


  ZnSe CO2 Laser Focus Lens D25.4mm for die board laser cutting machine 


 



Product Description


 




SPT manufacturing CO2 laser lens all adopt the U.S.A. imported CVD ZnSe. Imported CVD ZnSe


 has double -sided semipermeable films, which its main function is to decrease or eliminate the


 reflective light from lens, prisms, etc. and thus to increase these component transmittance level 


and decline or eliminate stray light.


 


Our CO2 laser lens have advantages over than those of others, such as low material absorption rate


 enduring high power density, firm surface membrane and resistant to wipe. 


In CO2 laser industry working band 10.6 um, our lenses are commonly used through rate of 99.8%. 


 


As a most economical transmission focus components, lens are widely used in some industries, 


such as laser heat treatment, welding, cutting and infrared radiation collection, in order to obtain


 satisfactory performance and achieve the purpose that the surface of the lens should be towards


 the direction of imputed light beam towards the conjugate distance the longer end.
