BI-BCC-12-18-U: 12mm Bi-Concave lens, Uncoated, FL=-18mm.
Bi-concave lenses have two inward-curved surfaces and a negative focal length. They diverge light, and are used to expand beams and to shorten the focal length needed in a system.

Center Thickness: 2.00 ± 0.05 mm
Edge Thickness: 3.76 mm
Focal Length (EFL): -18 mm
Back Focal Length (BFL): -18.65 mm
Surface Quality: 40-20 (scratch-dig)
Flatness / Irregularity: λ/4 P-V @ 632.8 nm
Coating: Uncoated (transmission 350–2200 nm)
