Description

  • Epaisseur ultra-fine, 0,20 mm
  • Substrat de précision en N-BK7
  • Extrêmement légères

Les Fenêtres Ultra-Minces en N-BK7 TECHSPEC® sont les fenêtres les plus minces que nous ayons, avec une épaisseur minimale de 1/10e par rapport à nos fenêtres N-BK7 traditionnelles. Leur concept extrêmement fin les rend parfaites pour des applications sensibles au poids et à la taille. Par ailleurs, leur concept haute-tolérance produit une distorsion et une dispersion du rayon minimes. Les Fenêtres Ultra-Minces en N-BK7 TECHSPEC® sont disponibles sans traitement ou avec un traitement MgF2 antireflet. Pour des dimensions sur mesure ou des options de traitement, veuillez contacter notre support commercial.

Remarque : Les Fenêtres Ultra-Minces en N-BK7 sont très fragiles. Manipuler ces fenêtres avec soin.
