BI-BCC-25-50-U: 25mm Bi-Concave lens, Uncoated, FL=-50mm.
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.

Material: N-BK7
Center Thickness: 2.50 ± 0.10 mm
Edge Thickness: 5.4 mm
Focal Length (EFL): -50 mm
Back Focal Length (BFL): -50.82 mm
Surface Quality: 40-20 (scratch-dig)
Flatness / Irregularity: λ/4 P-V @ 632.8 nm
Coating: Uncoated (transmission 350–2200 nm)
