Lens is a kind of optical component used for transmission or refraction light, converging, or diverging the beam. PHYO OPTICS provide many different types of lens fitting for the optical systems. Size can be Dia2.5mm to 400mm as requested. Including customized coating applied on surface. Normally lens material are chosen from CDGM or Schott if specially requested. Meanwhile, we have stocked lens parts for your reference some of them we can provide as free samples for quality evaluation.
Double Concave, in similar cased, still known as bi-concave lens. The same optical property with the Plano-concave lens. PHYO OPTICS supply double concave lens by N-BK7, Fused Silica, CaF2, SF11,H-BaK4,H-BaK7,etc, used as 190-2100nm based on different optical material and coating
