Please find below a short description of our PHYO High Quality -BK7, Fused Silica, CaF2, SF11, H-BaK4,H-BaK7 Achromatic Lens
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.
Achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. The most common type of achromat is the achromatic doublet, which is composed of two individual lenses made from different optical glasses with different refraction value. Typically, one negative lens with high dispersion material glued together with a positive lens with a lower dispersion material. Such as F2 negative lens glued with a BK7 positive lens to create an achromatic.
PHYO OPTICS still supply the apochromatic lens, which has better correction of chromatic and spherical aberration than the common achromat lens.
