Product Description
Features
Ø1" Positive Meniscus Lenses Fabricated from N-BK7 Glass
Available Uncoated or with One of Three AR Coatings:
Uncoated: 350 nm to 2.0 µm
A Coated: 350 - 700 nm
B Coated: 650 - 1050 nm
C Coated: 1050 - 1700 nm
Focal Lengths Available from -100.0 to -1000.0 mm
Spherical Surface Power: 3 Fringes
Spherical Surface Irregularity: λ/4
These Positive Meniscus Lenses are fabricated from RoHS-compliant BK7 glass (N-BK7) and are available uncoated or with one of our three broadband antireflection coatings: -A (350-700 nm), -B (650-1050 nm), or -C (1050-1700 nm). These coatings greatly reduce the 4% loss per surface incurred when using an uncoated lens.
Positive meniscus (convex-concave) lenses are designed to minimize spherical aberration. When used in combination with another lens, a positive meniscus lens will shorten the focal length and increase the numerical aperture (NA) of the system without introducing significant spherical aberration. When used to focus a collimated beam, the convex side of the lens should face the source to minimze spherical aberration.
