Description:
A Plano Concave Cylindrical Lens is a special kind of plano-concave optical lens component in columnar shape, with one plane side and one concave side. As a plano-concave lens, a plano-concave cylindrical lens has an inward bent curve, contributing to a negative effective focal length (EFL), and both of them perform best at infinite absolute conjugate ratios, and becomes not advantageous when below 5:1. The distinguishment is that the former diverges lights in two dimensions, the later expands light beam along a one-dimensional single axis. One of the critical functions of a Plano-concave cylindrical lens is transforming two-dimensional light beams into one-dimensional lines.Another application of Plano-concave cylindrical lenses is to correct for astigmatism and the elliptical shape of the laser beam.
N-BK7 or its equivalent known as H-K9L is a ROHS-compliant borosilicate crown glass with superior optical excellence and the glass is fine annealed and polished to tight tolerances to meet the demanding tolerances. The most attractive advantages of N-BK7 are its high optical homogeneities and high transmission to VIS and NIR spectra. Besides, the hardness, chemical and thermal resilience of N-BK7 are also remarkable, it contains low levels of inclusions and bubbles, therefore N-BK7 is excellent for making high-precision optical lenses.
This page features Hangzhou Shalom EO’s stocked N-BK7 Plano-Concave Cylindrical Lenses. The various focal lengths range from -3.9mm to -700mm, while the dimensions also come in diversities to accommodate your requirements. Standard coating options include Uncoated, 350-650nm, 650-1050 nm, and 1050-1580nm anti-reflection coatings to elevate the transmission of the lens substrate, while custom coating bandwidths could be tailored through inquiries. With unceasing devotion and engineering intelligence, Shalom EO has earned credits among researchers and clients around the globe. Before shipment, the cylindrical lenses will undergo a stringent in-house inspection in our clean room using Zygo interferometers and other equipment to secure your interest.
