CVI PCB‑25.4‑12.9‑C‑670‑1064 Plano-Concave Lens

CVI PCB‑25.4‑12.9‑C‑670‑1064 Plano-Concave Lens

• “25.4” → typically refers to 25.4 mm diameter (1 inch) optics, common in laser optics catalogs.

• “C” → often means the substrate material N‑BK7 (optical glass) or a specific coating type.

• “1064” → almost certainly refers to the laser wavelength (1064 nm, Nd:YAG fundamental).

• “670” → possibly a center wavelength or coating specification or a catalog sequence number.

• PCB → could be a Plano‑Concave optical element
