*All EFLs are calculated for wavelength 300 µm. EFL deviations related with refraction index dispersion at the edges of THz range (30-3000 µm) and within visible range are negligible in comparison with EFL tolerances manufactured.

 

Please check Optics stock.

Alternate sizes (max thickness 30 mm) and custom design are manufactured upon request.
