Reasonable Biconvex Lens BK7 30mm Diameter 41.3mm Focal Length 633 - 1064nm

S-SLB-30B-40PIR1

This lower cost product offering of Biconvex Lenses has only minimal reduction in quality and is perfect for most applications. It can be used in an optical systems such as observation or lighting applications when the higher surface quality Biconvex Lens (SLB-B-P) is not required.
◦It has the same specification of Biconvex Lens (SLB-N-P) except the surface quality and is ideal for experiments and applications where high-precision is not required.
◦There are two types of lens offer, a Plano convex lens with low spherical aberration and a biconvex lens that is used to shorten the focal length.
◦In addition to uncoated products, there are three types of anti-reflection coating for visible, near-infrared, and infrared.

Attention
  • Biconvex lens have a chromatic aberration, and the focal length will vary depending on the wavelength.
  • Please check the “wavelength characteristic of the focal length data” on “Technical Data” of Biconvex lenses (SLB-B-P) for the focal lengths of each wavelength.
  • WEB Reference Catalog Code/W3055-1
  • Transmissions losses due to reflection off the front and rear surfaces of the lens can be minimized by coating the surfaces. Consult our Sales Division for anti-reflection coatings suitable for your application.
